High-Precision Analyser for AM/FM Radio Technology

The Model 8201 AM/FM Modulation Meter offers a unique combination of measurements including AM, FM and PM, Carrier level and frequency, Signal, noise and distortion power (SINAD), thus eliminating the need for different discrete items of test equipment. With a carrier level resolution of 0.01dB, a frequency resolution of 10Hz and an accuracy of 1% AM and FM modulation measurements, the 8201 is well suited for the most demanding requirements.

Modulation is detected using peak, while residuals are measured using RMS and referenced to a specific level. These values are displayed in %, dB or quasi-peak, and the highest values are stored using the peak-hold function. Signal frequency and level can be acquired automatically or input via the keyboard or remote command. The 8201 is a cost-effective measurement tool for an ATE system, signal generator calibration or mobile radio production testing.
