Datasheet Accessory Kit
The Anritsu 68037B Synthesized CW Generator features 2 to 20 GHz frequency coverage. CW or step sweep, low SSB phase noise and spurious signals, output levels to +17 dBm, and optional 0.1 Hz resolution combine to make these sources ideal for local oscillator replacement applications. To meet requirements that expand over time, economical upgrades are available to any higher performing model. For the most demanding CW requirements, the 68037B provides the ultimate in performance.


  • Ultra-low SSB phase noise; –83 dBc at 10 kHz offset from 10 GHz
  • 2 to 20 GHz frequency coverage in a single coaxial output
  • Waveguide extensions to 110 GHz
  • Economical upgrades
  • +17 dBm maximum power, –125 dBm minimum power
  • User down-loaded complex modulation


CW mode Output Twenty independent, presettable CW frequencies (F0 to F9 and M0 to M9)
Accuracy Same as internal or external 10 MHz time base
Internal time base stability With aging: <2 x 10–8/day (<5 x 10–10/day with Option 16)
stability With temperature: <2 x 10–8/°C over 0°C(<2 x 10–10/°C with Option 16)
Resolution 1 kHz (0.1 Hz with Option 11)
Switching time <40 ms to be within 1 kHz of final frequency (typical maximum)
CW power sweep Range Sweeps between any two power levels at a single CW frequency
Resolution 0.01 dB/step
Accuracy Same as CW power accuracy
Step size User-controlled, 0.01 dB to the full power range of the instrument
Step dwell time Variable from 1 ms to 99 seconds. If the sweep crosses a step attenuator setting, there will be a sweep dwell of approximately 20 ms to allow setting of the step attenuator.
