Keysight (Agilent) 83650B Options:
- 83650B - 001 - Adds step attenuator (minimum settable output power –110 dBm; maximum leveled output power reduced by 1.5 dB to 20 GHz, 2 dB above 20 GHz, and 2.5 dB above 40 GHz)
- 83650B - 002 - Adds internal modulation generator (digitally synthesized modulation waveform source; 8360B only, not available on 8360L)
- 83650B - 004 - Rear panel RF output (moves RF output, external ALC input, pulse input/output, AM input, and FM input connectors to the rear panel)
- 83650B - 006 - Fast pulse modulation (improves pulse rise/fall time to 10 ns; also improves harmonic performance; 8360B only, not available on 8360L)
- 83650B - 008 - 1 Hz frequency resolution
- 83650B - 700 - MATE system compatibility (provides CIIL programming commands)
