Boonton 8701 VXI Modulation Meter

  • Carrier Frequency Range, 100 kHz to 2.5 GHz
  • Measures AM/FM/ØM
  • Provides Versatile Audio Filters
  • Peak RMS Detector
  • Measures Carrier Frequency and Level
  • Internal Calibrators (AM/FM/ØM) Standard


The Boonton 8701 VXI Modulation Meter offers a unique combination of measurement capabilities. Not only does it measure AM/FM/ØM with unprecedented accuracy, it also measures carrier frequency and level. This combination can eliminate the need for several additional pieces of test equipment by integrating them in one convenient package, at the price of a modulation meter alone.

The 8701 measures AM and FM to 1% of reading and phase modulation to 3%, carrier frequencies with 10 Hz resolution and levels to 0.01 dB and selects from 4 low-pass filters, Butterworth or Bessel, 4 high-pass filters, and 4 de-emphasis networks.

Modulation measurements are made with true peak detectors (plus, minus, or peak-to-peak divided by 2), residuals are measured with true RMS detection and displayed as a ratio to a selected reference level in either percent or dB. A peak HOLD function allows a running display of the highest measurement.

Operation can be completely automatic with internal frequency and level acquisition, or the carrier frequency and level can be entered remotely over the bus.

The 8701 is especially useful for ATE applications because of its high measurement speed.

The 8701 is a cost effective measurement tool that can be used for signal generator calibration or mobile radio production testing.

Product Family: 8701, 87O1
