Keysight 83712A Synthesized CW generator, 0.01 to 20 GHz


(From Used-Line T&M Specifications )
Status Discontinued
Alternative E8257D PSG Analog Signal Generator

The HP 83712A synthesized CW generator has a carrier frequency range of 10 MHz to 20 GHz.

  • Frequency
    • Range: 0.01 to 20.0 GHz
    • Resolution: 1 kHz, 1 Hz with option
    • Aging rate: <1.0 x 10-8/day after 72 hours, <1.5 x 10-9/day after 24 hour warmup - with option
    • Frequency switching time: <50 ms to within 1 kHz
  • RF output
    • Maximum leveled output power: +13 dBm at 0.01 - 1 GHz, +11 dBm at 1-20 GHz (+10 dBm with option)
    • Minimum leveled output power: 0 dBm, -90 dBm with option
    • Display resolution: 0.01 dB
    • Flatness: ±0.5 dB for power ≥-90 dBm, ±0.7 dB for power <-90 dBm (The use of Type-N RF connectors above 18.0 GHz degrades specification typically by 0.2 dB)
    • Level switching time: <17 ms (without step attenuator range change)
    • Output SWR: <2.0:1 nominal
  • Harmonics: <-55 dBc at output levels <+6 dBm, 0.01 to 1 GHz; <-50 dBc at output levels <+6 dBm, 1 to 20 GHz
  • Non-harmonic spurious: <-60 dBc (≥3 kHz), <-50 dBc (<3 kHz)
  • Residual FM: At 1 GHz, <15 Hz in 50 Hz to 15 kHz bandwidth. Residual FM decreases 6 dB per octave below 1 GHz
  • AM noise floor: (at 0 dBm and offsets greater than 5 MHz from carrier) <-150 dBm/Hz, 1-20 GHz; <-140 dBm/Hz, 0.01-1 GHz
  • Front panel connectors
    • RF Output: The standard front panel RF Output connector is a Type-N precision connector. When Option 1E9 is installed, this front panel connector is a 3.5 mm precision connector. The nominal source impedance is 50 Ω
    • ALC In: This front panel BNC connector allows the synthesizer to be externally leveled. It is used with external power meter leveling or external diode leveling. The leveling signal at this input must be in the ±1 V range. The nominal input impdeance is 150 Ω. The damage level is ≥+12 V or ≤-12 V
  • Rear panel connectors
    • 10 MHz Input: Accepts a 10 MHz ±100 Hz, 0 to +10 dBm, external reference signal for operation from an external high stability timebase. Nominal input impedance is 50 Ω
    • 10 MHz Output: Outputs the 10 MHz reference signal, nominally at +3 dBm, for use as an external reference signal. Nominal source impedance is 50 Ω
    • 0.5 V/GHz Output: Supplies a voltage proportional to output frequency for use with mm-wave frequency multipliers, including the 83550 Series Millimeter Wave Source Modules
  • Options
    • 1E1: Output Step Attenuator
    • 1E2: Internal AM and FM/ΦM sources
    • 1E5: High stability timebase
    • 1E8: 1 Hz frequency resolution
    • 1E9: 3.5 mm RF output connector (male APC-3.5)
