射频毫伏表

此款射频毫伏表具体参数如下：
Voltage Range 200 μV to 10 V in eight ranges

divider) indications to 50 μV
Voltage Display 1 mV to 300 V fs
Decibel Range (> 90 dB in eight ranges, 0.001 dB resolution)
dBmV, 0dB = 1 mV
dBV, 0dB = 1V
dBW, 0dB = 1W
dBm, 0dB =1mW
(Calculated from voltage drop across a selectable Z
Reference 5 to 2000Ω)
dBr, 0dB = any reference level
(Reference level can be selected at front panel to 0.001 dB resolution
if display range of +/-99.99 dB is not exceeded)
Frequency Range
