The Rohde-Schwarz FSP7 is a member of the FSP range of spectrum analyzers, which are outstanding for their innovative measurements and a host of standard functions.
Instead of a wide choice of options, the FSP offers as standard all the functions and interfaces expected from a state-of-the-art spectrum analyzer: - Largest colour display in its class - Resolution bandwidths from 1 Hz to 10 MHz - Highly selective digital filters and FFT - Quasi-peak detector and EMI bandwidths - ACP and multicarrier ACP measurements - Convenient documentation of results as a hardcopy or file in PC-compatible formats - Interfaces: GPIB, Centronics, RS-232-C, LAN (option), USB - Automatic test routines for measuring TOI, OBW, phase noise and ACP(R) - Split screen with separate settings and up to 3 traces per screen - Editable limit lines including PASS/FAIL indication - Fast measurements in the time domain: minimum sweep time 1 s - Gated sweep for measurements on TDMA signals.
In addition, the FSP features the following unique attributes as standard: - RMS detector for fast and reproducible power measurements on digitally modulated signals in frequency and time domain - Statistical measurement functions for determining crest factor and CCDF (complementary cumulative distribution function).
Featuring such a wealth of functions, the FSP offers state-of-the-art spectrum analysis at an extremely attractive price/ performance ratio.
Time is a finite resource so high measurement speed is indispensable for competitiveness and cost-effective testing. Here, too, the new FSP offers characteristics that make it top of the class: - Up to 55 measurements/s on GPIB interface including trace transfer of 501 binary data - 80 measurements/s on GPIB interface in zero span mode including trace transfer of 501 binary data - Minimum sweep time of 2.5 ms 1 s time domain measurements - Unique fast ACP mode for high-speed ACPR measurements in time domain using the standard-compliant test filters - List mode for fast, selective power measurements.
With 100 measurements/s in manual operation and digital filters with a sweep time 2.5 times faster than comparable analog filters, the FSP will also prove beneficial in the day-to-day tasks of product development.
Modern communication systems should provide optimum spectral efficiency at high data rates. For the 3rd generation of CDMA mobile radio systems currently under development, this is achieved through functions such as among other things, by high-precision power control.
The FSP is the ideal partner in development and production, featuring low uncertainty in level measurement, as well as excellent RF characteristics: 0.5 dB total measurement uncertainty allows higher tolerances for the DUT, thus increasing production yield - 0.07 dB linearity uncertainty (1 s) is ideal for precise measurements, for example of gain control and ACPR - RMS detector with >100 dB dynamic range measures power fast and accurately irrespective of the signal shape almost like a thermal power sensor - The displayed average noise level of typ. 155 dBm (1 Hz) is attained without the use of preamplifiers and thus without any reduction in dynamic range - Typ. 145 dBc (1 Hz) phase noise at 10 MHz offset offers optimum conditions for ACPR measurements on WCDMA systems.
Resolution bandwidths of up to 100 kHz are fully digital and provide in addition to high selectivity an ideal basis for accurate (adjacent-) channel power measurements owing to a maximum bandwidth deviation of 3%.
Top-class performance as offered by the FSP essentially depends on the extensive use of digital signal processing and large-scale integration of components. For these demanding tasks, Rohde + Schwarz has developed ASICs tailored to the requirements of signal analysis. Key functions such as - RMS detection - Digital IF filtering - Logarithmation - CCDF measurement are cast in silicon and are thus faster than conventional solutions.
The RMS detector a unique feature in all current Rohde+Schwarz spectrum analyzers quickly yields stable and reproducible results even for complex signals such as CDMA. By performing a very large number of linear single measurements, followed by power integration, the detector avoids the measurement error inherent in conventional analyzers that arises from the averaging of the log video signal. The RMS detector of the FSP measures all modern communication signals with unparalleled accuracy and speed.
The FSP comes equipped with digital resolution filters between 10 Hz and 100 kHz featuring high selectivity and very low bandwidth deviation. The filters have an extremely low logarithmic level deviation of <0.2 dB in the range 0 dB to 70 dB. As they are implemented as ASIC functions, their great precision is attained without any reduction in measurement speed.
The complementary cumulative distribution function (CCDF) describes the probability of a signal power exceeding a specific (usually the average) power. CCDF analysis is indispensable for determining the optimal transmitting power for CDMA signals, assuming that clipping over known, short intervals is tolerable. The FSP with its dedicated CCDF measurement routine furnishes 106 single values in only 250 ms, thus enabling extremely accurate statistical analysis even of rarely occurring signal peaks.
This analysis function, which is becoming more and more important, has been implemented for the first time in the Spectrum Analyzer FSP as a fast and cost-effective solution based on ASICs.
Excellent specifications such as those of the FSP require a high-grade and service-friendly platform. All the modules are optimally shielded and easy to exchange, and are accommodated in a lightweight but stable frame. A powerful low-noise fan in conjunction with low power consumption of 70 VA to 150 VA (depending on model) makes for high reliability. A 2-year calibration interval (excluding the reference frequency) is offered with the FSP.
Owing to its modular design, the FSP is optimally equipped to handle all present and future tasks. The design takes into account both hardware and firmware extensions to safeguard your investment far into the future. Thus, you can also rely on your FSP to meet all requirements that will arise in the years to come.
The FSP sets the ergonomic standard in this class of analyzers. The 21 cm (8.4) colour display is the largest and most brilliant in its category. Vertical and horizontal rows of softkeys allow even complex measurement tasks to be performed easily. Parameters such as frequency and amplitude are entered by means of dedicated hardkeys and unit keys.
Featuring the lowest displayed average noise level in its class (DANL <-145 dBm at 10 Hz RBW), the FSP measures even small signals accurately without using preamplifiers that reduce dynamic range. Together with the high intercept point, this yields an intermodulation-free range of typ. 100 dB yet another record among medium-class analyzers.
In the vital frequency range below 3 GHz, the FSP is outstanding for its ultralow measurement uncertainty. The total measurement uncertainty is less than 0.5 dB. Due to this excellent value, the use of power meters in routine lab applications very often becomes superfluous and may greater tolerances are possible for DUTs.
The unique RMS detector measures modern, noise-like communication signals with optimal repeatability and stability. As there are neither correction factors nor the typical errors caused by averaging of logarithmic trace data, the correct average power is displayed with high stability for all signal types almost like in measurements with a thermal power meter.
Owing to its excellent display linearity, the FSP is also ideal for noise figure measurements. Software FS-K30 enhances the FSP to form a noise measurement system offering analyzer-specific advantages.
The low phase noise of the FSP makes it suitable for demanding measurement tasks both in the vicinity of the carrier (typ. 113 dBc (1 Hz) at 10 kHz) and far from the carrier (typ. 125 dBc (1 Hz) at 1 MHz). The FSP is thus optimally equipped for performing spectral analysis and ACPR measurements on narrowband systems such as IS136 or PDC as well as on wideband systems such as IS95 or WCDMA. Phase Noise Measurement Software FS-K4 enhances the Spectrum Analyzer.
The FSP is the first spectrum analyzer to offer statistical analysis of signals by means of the complementary cumulative distribution function (CCDF) as standard and at an impressively high speed. The FSP furnishes in only 250 ms the exact CCDF characteristic, average and peak power as well as the crest factor covering 1 million measured values.
Adjacent-channel power ratio (ACPR) measurements, which many mobile radio standards stipulate for components and devices, are implemented in the FSP by means of automatic test routines.
All settings, measurements and filters required for a selected standard are activated at a keystroke. In addition to a large number of preprogrammed standards, the channel width and channel spacing can be individually selected.
Owing to the excellent dynamic range, lowest phase noise in its class and the
RMS detector, the FSP sets the standard in the medium class also for ACPR measurements.
With 100 measurements/s in manual operation, a minimum sweep time of 2.5 ms and 1 s zero span as standard, the FSP is ideal for time-critical applications. The highly selective, fastsweep digital filters featuring analog response allow measurements on pulsed signals as well as the use of the built-in frequency counter.
The FSP comes standard with different filter types for digital resolution bandwidths up to 100 kHz such as Gaussian filter, raised root cosine (RRC) filter and steep-sided channel filters. Up to a resolution bandwidth of 30 kHz, fast Fourier transform (FFT) is available in addition.
In the analyzer mode, the Gaussian filters have the advantage of high sweep speed plus excellent resolution. At high span/RBW ratios, measurements using FFT can be as much as 300 times faster than measurements with digital filters.
Some mobile radio standards such as TETRA and IS136 require RRC filters for power measurement, a type of filter already included in the FSP. In addition, the FSP provides channel filters for other analog and digital methods, e.g. cdmaOne, AM/FM radio and ETS 300 113. Adjacent-channel power due to switching can also be measured using the channel filters. For the common mobile radio standards, the FSP is equipped with test routines (fast ACP) that allow the adjacent-channel power in the time domain to be determined, which reduces measurement time and increases reproducibility. 55 measurements per second on GPIB interface.
The high-speed GPIB interface enables up to 55 measurements/s including trace data transfer of 501 test points with the display switched off. In the zero span mode, 80 measurements/s are possible. This characteristic makes the FSP by far the fastest spectrum analyzer on the GPIB interface. Valuable time can be saved in production, boosting throughput enormously. The FSP thus supports you in getting your products more costeffective on the market. 0.2 dB maximum linearity uncertainty.
All modern mobile radio systems achieve high spectral efficiency through precise control of transmitter output power or other means. The correct functioning of gain control, which may be as much as 70 dB depending on the system, is checked against the nominal value in a large number of individual measurements.
Featuring a maximum linearity uncertainty of only 0.2 dB and fast power measurement routines especially for digitally modulated signals, the FSP is the ideal choice wherever the reduction of the test time and the number of rejects is of primary importance.
Measurement uncertainty can be split into the part from the instrument and that introduced by the test setup. With lower uncertainty of the spectrum analyzer, greater tolerances can be allowed for the test setup. If the lower uncertainty of the analyzer is utilized to allow for higher DUT tolerances, the result will be a marked reduction of manufacturing rejects an advantage that pays off immediately. With a total measurement uncertainty of 0.5 dB, the FSP undisputedly ranks at the top, way ahead of other mediumclass analyzers.
The FSP offers fast routines for a multitude of typical measurement tasks, which make result postprocessing superfluous by supplying the desired data directly: - Determination of TOI - Occupied bandwidth (OBW) - Burst power with peak, average and RMS indication as well as standard deviation - Modulation depth of AM signals - Phase noise - Bandwidth marker. Of course these functions can also be used via the fast GPIB interface.
In the List mode, the user only has to enter a few IEC/IEEE bus commands to perform measurements on up to 100 frequencies with different instrument setups in each case. A single command configures the list, and frequency, bandwidths, measurement time, reference level and RF attenuation can be set independently of each other. The SENSE:LIST:POWER:RESULT- query, for example, simultaneously transfers all measurement results to the process controller after the list has been processed. This feature reduces the time required for transfer via the IEC/IEEE bus. In conjunction with the very high measurement speed of the FSP, it also allows the generation of time-saving test routines in production applications. The optional Trigger Port FSP-B28 allows idle times between the different settings to be minimized.
The optional Electronic Attenuator FSP-B25 supplements the standard mechanical attenuator and provides a wear-and-tear-free setting range of 30 dB in 5 dB steps. The option does away with frequent switching of the mechanical attenuator as required for high throughput in production and so increases the availability and reliability of the measurement equipment. For example, the limit of 107 switching operations, which is typical of mechanical attenuators, already means a breakdown after approx. 6 months at 1.5 switching operations/s whereas the Electronic Attenuator FSP-B25 can be switched any number of times without impairing the specifications.
The integrated switchable 20 dB preamplifier allows high-sensitivity measurements in the useful frequency range from 10 MHz to 7000 MHz.
With the aid of the optional LAN Interface FSP-B16, the FSP can be connected to common networks such as 100Base-T so that functions such as file logging on network drives or documentation of measurement results via a network printer are available. In addition, the FSP can be remote-controlled via LAN), which is especially easy with the WindowsXP Remote Desktop function. This yields a clear speed advantage over the IEC/IEEE bus, in particular for the transmission of large data blocks.
In many applications, existing test software is to be used in automatic test systems alongside new devices. For this reason, the FSP comes standard with an IEC/IEEE bus command set that is compatible not only with the FSEx/FSIQ family but also with the spectrum analyzers of the 859x/8566 series. Thus importance was placed on maximum compatibility in order to minimize the necessity for changes. - Approx. 175 commands in IEEE488-2 format (incl. CF, AT, ST) - The most important commands in IEEE 488-1 format (8566A, for exclusive use only) - Selectable presets - Selectable trace format 8560E to 8565E, 8566A/B, 8568A/B and 8594E are supported. The IEC/IEEE bus commands in IEEE488-2 format can be used together with the FSP command set, making it possible to enhance and complete available software by using the innovative instrument functions of the FSP (such as list mode, channel filters) without having to redesign the test software.
