HP 3400A RMS Voltmeter

Description

HP 3400A RMS Voltmeter s/n
2415A34344
Up for your consideration is a very nice Hewlett Packard model 3400A RMA Voltmeter.
General Description:
The model 3400A measures the actual RMS value of AC voltages between 100 microvolts and 300 volts. Full-scale measurements of non-sine waveforms with crest factors (i.e., ratio of peak voltage to rms voltage) can also be made. The frequency range of this meter is from 10 Hz to 10 MHz.
Basic Specifications
*
VOLTAGE RANGE:
1 mV to 300 V full scale, 12 stages
DB RANGE:
-72 to 52 dBm (0 dBm = 1 mW in 600Ω)
FREQUENCY RANGE:
10 Hz to 10 MHz
RESPONSE:
Responds to rms value (heating value) of input signal
MAX DC INPUT:
600 V on any range
* A more detailed specification list can be found in the operation manual.
Physical Condition:
This unit is in excellent condition as you can see from the photos.
It has its original feet, tilt bale and handle.
The side panels, top and bottom panels are nearly perfect.
There are light scratches on top front bezel from calibrate stickers. Front panel is excellent with no damage.
Internal circuitry is unmodified and
very
clean.
Electrical Operation:   Aligned and working.
Note I used an HP 10100C 50Ω feedthrough (not included) and my calibrated HP 8640B signal generator (also, not included) for my tests.
PLEASE NOTE:
The 3400A may show a zero offset with no voltage applied to the input (i.e., the meter may not rest on zero). This is normal.
This meter will include a .pdf version of the operating and service manual (which does pertain to this unit’s serial number prefix) and an AC cord.
The 50Ω feedthrough is not included.
