- Full S-Parameter measurements
- 30kHz to 3 or 6GHz frequency range
- Integrated 1Hz resolution synthesized source
- Up to 110 dB dynamic range
- Built-in accuracy enhancement
An integrated, synthesized source provides >100 mW of output power, 1 Hz frequency resolution, and linear, log, list, power, and CW sweep types. Three tuned receivers allow independent power measurements or simultaneous ratio measurements over a wide dynamic range of 105 dB at 6 GHz (with Option 006 frequency extension) or 110 dB at 3 GHz (standard). The integrated test set allows you to measure transmission and reflection characteristics of a device to 6 GHz without a frequency doubler.
TRL/LRM calibration has been added for convenient, accurate measurements in non-coaxial environments. A high-stability frequency reference, Option 1D5, improves the frequency accuracy of measurements on high-Q devices such as SAW resonators or dielectric resonance filters. For configuration flexibility, Option 011 deletes the built-in test set so that you can select your own. The HP 8753D Option 011 works with the HP 85046A/B, 85047A, and other test sets.
A test-sequence function allows rapid, repeated execution of complex tasks with a single keystroke. In sequencing mode, you make a measurement once from the front panel, and the analyzer stores the keystrokes so that no additional programming is required. You can also use a test sequence to control external devices through the parallel port.
Other productivity enhancements include a built-in disk drive supporting LIF and DOS formats, a faster CPU clock rate, non-volatile memory of 512 KB, serial and parallel interfaces, a DIN keyboard interface, and a real-time clock for time-stamping of printouts and files. Limit testing, arbitrary frequency testing, and marker tracking functions are included. Segmented calibration and interpolative error correction allow you to apply vector accuracy enhancement over a subset of the analyzer’s calibrated frequency range.
For nonlinear device characterization, Option 002 adds harmonic measurement capability. Swept second- and third-harmonic levels of an amplifier can be displayed directly or in dBc. With the press of a button, you can measure harmonics down to –40 dBc. Power meter calibration provides leveled absolute power to devices that are sensitive to absolute input or output levels. The HP 8753D automatically controls an HP 436A, 437B, or 438A power meter to set the power anywhere in the test configuration with power meter accuracy. The analyzer also performs mixer tracking and conversion loss measurements. Both fixed and swept IF measurements can be made.
With Option 010, you can view responses in the time domain. The analyzer computes the inverse FFT of the frequency-domain data to display the reflection or transmission coefficient versus time. Two time-domain analysis modes enable you to view the step or impulse response of your device, or to remove unwanted responses such as connector mismatch using gating.
