83752A Agilent RF Generator


The 83752A is a 20 GHz RF Generator from Agilent. An RF generator is a tool engineers use to generate sinusoidal outputs while testing electronic equipment. The output will automatically have its frequency varied or swept between frequencies. A “sweep” is one complete cycle of a frequency variation. Engineers use RF signal generators as test equipment, mostly to measure responses of filters, amplifiers, and electrical components.

Additional Features:

  • Frequency Range: 10 MHz to 20 GHz
  • Fully phase locked analog sweep for accuracy and speed
  • Flat and accurate output power to characterize the linear response of the test device
  • Offset frequency sweep for mixer test
  • Agilent 8350 programming mode for backwards compatibility
  • Standard 10 MHz time base: ±10 ppm
  • High stability time base (Option IE5): accuracy = calibration ± aging rate ± temperature effects ± line voltage effects
  • Aging rate: 5 x 10-10/day, 1 x 10-7/year
  • With temperature: 1 x 10-10/°C
  • With line voltage: 5 x 10-10 for 10% change

CW mode

  • Resolution: 1 Hz
  • Accuracy: same as time base
  • Switching time: 70 ms max

Stepped sweep mode

  • Resolution: settable 1 Hz, display 1 kHz
  • Accuracy: same as timebase
  • Minimum step size: same as resolution
  • Number of points: 2 to 1601
  • Switching time/point: 7 ms + 8 ms/GHz step
  • Dwell time/point: 1 ms to 1 s

Ramp (analog, phase locked) sweep mode

  • Resolution: 1 kHz
  • Accuracy (25 ±5 °C):
  • For 100 ms sweeps the greater of: ±.01% of span ±time
  • base or ±75 kHz ±time base
  • At other sweep speeds: [±.001% of span]/[sweep time (s)] ±time base


  • 10 independent continuously variable markers
  • Display modes: z-axis intensity or RF amplitude pulse

Sweep functions

  • Start/stop, center frequency/span, marker, ramp,
  • stepped, manual, alternate and power sweep
  • Marker sweep: sweeps between markers one and two
  • Alternate sweep: alternates successive sweeps between current front panel setting and stored setup

RF output

  • Maximum leveled power (25 ±5 °C): +10 dBm
  • With option 1E1 (step attenuator): reduce by 1 dB
  • Minimum settable power: -15 dBm
  • With option 1E1: -85 dBm


  • Settable: 0.01 dB
  • Display: 0.1 dB

The Agilent 83752A sweeper brings outstanding synthesized performance to the component-test marketplace. It delivers the best performance for the price in general purpose benchtop, swept test or scalar applications. This sweeper provides superior accuracy and stability while maintaining the speed of an analog source. Fully synthesized CW, stepped and ramp sweep modes are available in broadband and narrowband operation.

The synthesis capability is particularly useful for the characterization of narrowband devices, in which the frequency instabilities of open-loop sources become most apparent. Excellent output power flatness and accuracy can be translated to the input port of the device under test with the power flatness correction feature of this source.
