The HP 83731A 20 GHz synthesized signal generator's fundamental oscillators and switched low-pass filters deliver < -55 dBc harmonics, eliminate subharmonics, and suppress spurious to < -60 dBc. These signal sources provide plenty of output power (typically> + 14 dBm), while spectral purity is maintained even at high power levels (typical output power at frequencies below 1 GHz is + 20 dBm). These signal sources deliver > 100 dB dynamic range. Level resolution is 0.01 dB with typical accuracy of ± 1.0 dB at any frequency or power level. User Level Correction simplifies generating accurate, leveled power at distant test ports. Test 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 receivers. A built-in multimode pulse generator adds the flexibility to generate triggered, doublet, and gated burst pulse modes. Specifications. Frequency Range: 1.0 to 20 GHz. Frequency Resolution: 1 kHz, 1 Hz with Opt 1E8. Output power (with Opt 1E1): +13 dBm (0.01 to 1 GHz), +10 dBm (1 to 18 GHz), +8 dBm (18 to 20 GHz ). Resolution: 0.01 dB. Harmonics: < -55 dBc (at levels < +6 dBm). Sub-Harmonics: None. Non-Harmonic Spurious ( > 3 kHz): -60 dBc. Pulse Modulation On/Off Ratio: > 80 dB. Rise/Fall Times: < 10 ns. Minimum Pulse Width: <25 ns, 1 to 20 GHz. Frequency Modulation Rates: 1 kHz to > 1 MHz. Options. 1E1, Add 90 dB Output Step Attenuator. 1E5, Add High·Stability Timebase. 1E8, Add 1 Hz Frequency Resolution. 1E9, 3.5 mm RF Output Connector.
