Test radar, electronic warfare (EW), and communication receivers with confidence from 10 MHz through 20 GHz. Excellent spectral purity, high output power, and sophisticated modulation are combined in an affordable, lightweight, easy-to-use signal generator.
Choose the HP 83731A, 1 to 20 GHz, or the HP 83732A 10 MHz to 20 GHz, for your receiver and system test applications. You can count on the HP 83731/32A for excellent spectral purity. Fundamental oscillators and switched low pass filters deliver < - 55 dBc harmonics, eliminate subharmonics, and supress spurious to < - 60 dBc. Not only does the HP 83731/32A provide plenty of output power (typically > +14 dBm), but spectral purity is maintained even at these high power levels. Typical output power at frequencies below 1 GHz is + 20 dBm. Level resolution is 0.01dB with typical accuracy of +/- 1.0dB at any frequency or power level. User Level Correction simplifies generating accurate, leveled power at distant test ports.
Sophisticated modulation lets you simulate real-world signals. Test state-of-the-art radar and EW receivers with high-fidelity pulse modulation, < 10 ns pulse rise/fall times, < 25 ns pulse width, and> 80 dB pulse on/off ratio give you the performance you need to verify modern receivers. A built-in multimode pulse generator adds the flexibility to generate triggered, doublet, and gated burst pulse modes.
In addition, logarithmic AM is a standard feature in the HP 83731/32A. Use the> 60 dB depth log AM and the fast pulse modulatlon simultaneously (scan modulation) for accurate simulation of antenna scanning patterns, or sweep power linearly and accurately to test power-sensitive devices.
The HP 83731/32A offer unmatched performance for testing satellite communications and telemetry receivers. 10 MHz peak FM deviations, combined with the highest modulation index available (> 300), simplify simulation of these difficult-to-generate signals. The HP 83731/32A remain fully synthesized even at high modulation indices, eliminating the troublesome frequency drift of other sources.
Real-world signals often combine two or more modulations. HP 83731/32A let you use all three modulations simultaneously without any degradation in performance. When your applications require high performance modulation, excellent spectral purity, and output power, the HP 83731/32A offer unparalleled capability.
For applications at frequencies below 1GHz, the HP 83732A offers several unique advantages. Digital dividers and switched filters minimize harmonics (< - 55 dBc) and spurious signals even at power levels approaching + 20 dBm. Now you can test receivers at their IF with the same high performance modulation you need at microwave. Phase noise and spurious supression improves by 6 dB/octave as frequency is reduced, making the HP 83732A a versatile solution both microwave and in-channel RF receiver tests. Broadband noise is improved greatly compared to older designs. The HP 83731/32A are recommended local oscillators for HP 8970B noise figure meter. Low broadband noise minimizes errors in measurements of low gain devices. Use the HP 83731/2Awith HP 83550 Series millimeter wave modules to generate signals to 110GHz. All front panel functions are completely HP-lB programmable and SCPI compatible.
