Description
The Model MV-3100A is a single band Millivolt Meter for measuring AC voltages from 0.3mV to 100V in 12 ranges with bandwidth of 5Hz to 1MHz. Each range shares 10 dB. The effective sensitivity at 0.3mV range is 30 u V. This voltmeter is equipped with three color scales for easy visual distinction, namely Volt, dB and dBm. As the result of employing FET in the inner circuit of this instrument, the input impedance is 10M W.
