Agilent / HP / Keysight 3581C
3581C Selective Level Meter
Description
This unit is a used selective voltmeter that covers the frequency range of 15Hz to 50KHz.
It has wide application in testing special service circuits in both inside and outside plant maintenance.
It can do spectrum analysis, measure non-linear distortion and locate and measure unwanted spurious and induced tones.
