The HP 8665B RF Signal Generator is for high-performance applications up to 6.0 GHz, particularly radar, telemetry and spurious testing of UHF receivers. FM rates of up to 2 MHz and deviations to 20 MHz peak are suitable for many applications such as higher-rate digital communications. An optional pulse modulator with on/off ratio of > 80 dB and rise/fall times of < 5 ns is available. Pulse width and delay can be internally adjusted between 50 ns and 999 ms, eliminating the need for an external pulse generator. Specifications. Frequency Range: 0.1 to 6000 MHz. Resolution: 0.01 Hz. Accuracy: Timebase stability x fc. Switching speed (typical): < 100 ms (Option 004). SSB phase noise @ 1 GHz (20 kHz offset): –117 dBc/Hz, –134 dBc/Hz (Option 004). Output LevelRange: + 13 to –139.9 dBm, + 9 dBm (Option 008). Resolution: 0.1 dB. Absolute accuracy: ± 1 dB, output >= –119.9 dBm 1 to 1000 MHz; ± 1.5 dB, output >= –119.9 dBm, 1000 to 3000 MHz. Interface: GPIB (IEEE 488.2-1987). Options. 001, High-Stability Timebase. 002, 2 GHz Doubled Output. 004, Low-Noise Option. 005, Electronic Attenuator (N/A with Option 002). 008, Pulse Modulation. 009, Specified VOR/ILS2. 011, 2 GHz Internal Frequency Counter. 003, Rear-Panel Input/Output. 010, Reduced-Leakage Configuration.
