3406A RF VOLTMETER
This RF Voltmeter has an extremely wide 10KHz to 1.2GHz bandwidth with high impedance.
p>Other features of the used HP Voltmeter include a DC recorder output, sample hold output for connection to oscilloscopes (>200Kohms load with <1000pF output is 0.316 V full scale), and peak or true RMS voltmeters if other absolute average measurements are required.
Full scale accuracy is within 3% over the greatest part of the band, and within 5 to 13% from 10KHz to 100KHz and 100MHz to 1.2GHz.
p>Maximum input is 100V DC, 30V peak to peak and meter response time is <3S.
Signals as small as 50µV can be resolved on the Voltmeter's linear scale
Full Scale sensitivity from 1mV to 3V is selected in eight 10dB steps and may be read directly from -62dBm to +23dBm for power measurements
Full scale accuracy is within 3% over the greatest part of the band, and within 5 to 13% from 10KHz to 100KHz and 100MHz to 1.2GHz
