The TVT-322 is a 2 Channels AC Millivoltmeter, providing an AC voltage measurement range of 300uV to 100V full scale with a bandwidth of 10Hz - 1MHz for both CH1 and Ch2. Two different input signals can be measured simultaneously or seperately according to the setting of a push button mode switch. The TVT-322 employs BNC input connectors, eliminating influence by extend induction during low level measurements.

This instrument can be used as a level meter with both the dB(0db=1Vrms) and dBm (0dBm=1mW/600!)scales, either AC output terminals are provided for each channel on the rear panel, so the CH1 and Ch2 signals can be observed on oscillscope and the TVT-322 can operate as a preamplifier.
