If in the following procedure the HP 3400A appears to be non-linear, it could be caused by ground loops. If this is noted, isolate the HP 3400A from the ac power line by using an isolation transformer between the ac power line and the Mode! 3400A. CHANGE NO. 4. Applies to Serial Numbers 2415A31801 and Above

Introduced in the 1963 general catalog, the HP 3400A is an rms-Responding Voltmeter with high crest factor rating. This rating is the measure of the voltmeter's ability to read the rms value of waveforms that have a high peak-to-rms ratio such as low-duty-cycle pulse trains, electrical or acoustic noise, and voltages of undetermined waveform.

2019年11月17日 · The 3400A is a true RMS responding AC meter using a pair of internal thermocouples. Voltage range is 1mV to 300V and frequency response is 5Hz to 10MHz. Accuracy is specified as 1% over most of the frequency range. Meter movement is calibrated to better than 0.5% at the factory during manufacture.

2025年3月13日 · The 3400A is a 10 Hz to 10 MHz True RMS Voltmeter, with 1 mV to 300 V full scale, 1 mV sensitivity, 10 MOhm input impedance, -72 to +52 dBm, Accuracy: 1% full scale. HP 3400A Meters > Voltmeters

The HP 3400A has 10 Mhz bandwidth and True-RMS readings via a thermocoupling bridge which measure the heating component of the voltage. This makes it superior to conventional analog and digital voltmeters where regular analog meters top out …
