Agilent / HP / Keysight 400FL
400FL AC VOLTMETER
Description
This AC Voltmeter is primarily intended as a dB Meter, however it can indicate both V and dB.
The meter has a linear dB scale with a logarithmic AC scale below.
The voltage range is 100µV to 300V full scale.
Meter calibration responds to the absolute average value of the applied signal, calibrated in RMS Volts from 20Hz to 4MHz.
