2CH AC Millivolt Meter Troneer TVT-322

2CH AC Millivolt Meter Troneer TVT-322The TVT-322 is a 2 CH AC millvoltmeter, 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 separately according to the setting of a push button mode switch.The TVT-322 employs BNC input connectors,eliminating influence by extence induction during low level measurments .This instruments can be used as a levelmeter with both the dB*0dB=1Vrms) and dBm (0dBm=1mW/600) scales,either AC output terminals are provided for each CH on the rear panel ,so the CH1 and CH2 signals can be observed on oscilloscope and the TVT-322 can operate as a preamplifier.Features: Wide band range : 5Hz-1MHz Testing Range: 300uV-100V Three scales, mV/dB/dBm for reading easily High stability and high reliabilitySpecification Voltage Range: 300uV-100uV (full scale) in 12 range dB range :-70dB to 40dB in ranges(0dB = 1Vrms) Accuracy: +/-3% of fullscale (at 1KHz or 400Hz)Input Impedance :10MHz for each range 40pF or less Bandwidth: +/- 3% 20Hz-200KHz +/- 5% 10Hz -500KHz +/-10% 10Hz-1MHzNoise:Within 2% of full scale by shortening inputMaximun input (DC + ACp-p): 300V (300uV-1V range) 500V (3V-100V range)Amplifier Output: 0.1Vrms +/- 10% at open loadOutput Impedance: 600ohm[ +/-10%Power Supply : AC 110V/220V/50/60Hz approx.Postnet or Courier Guy @ R 120
