Agilent / HP / Keysight 400E
400E AC VOLTMETER
This unit is an AC voltmeter from 10Hz to 300V fs in 12 ranges, and it's input impedance is 10MOhm.
Voltage range is 1mV to 300V full scale.
dB range is -72dBm to +52dBm.
Meter calibration responds to the absolute average value of the applied signal, calibrated in RMS volts from 10Hz to 10MHz.
Accuracy as a % of reading is: ±4% (10 to 20Hz), ±2% (20 to 40Hz), ±1% (40Hz to 2MHz), ±2% (2 to 4MHz), ±4% (4 to 10MHz).
Input impedance is 10Mohms.
AC amplifier output is 150mV rms open circuit for full scale meter indication.
Voltage range: 1mV to 300V F.S. 12 ranges
Frequency range: 10Hz - 10MHz
p>Input impedance: 10 MO on all ranges <25pF to <12pF depending on ranges
