The HP/Agilent 83640A is a synthesized sweeper delivering precision signal generation from 10 MHz to 40 GHz for aerospace, defense, and communications test environments. It combines the frequency accuracy of a synthesized source with the sweep speed and versatility of a dedicated oscillator, supporting simultaneous pulse, amplitude, and frequency modulation with output power levels from +20 dBm to −110 dBm (with Option 001). The instrument provides three sweep modes—step, list, and ramp—with switching times as fast as 5 ms for steps ≤100 MHz within a band, making it suitable for component test, receiver characterization, and frequency conversion applications.
