Hewlett Packard HP 400 AC Voltmeters:

The HP-400 series are the standard for good quality
voltmeters with a wide frequency response (20 Hz to
4 MHz). These meters have an amplified output
terminal that can be used as a preamp for a digital
scope, a chart recorder, etc.

The HP 400 meters are all RMS reading AC voltmeters
with a large mirrored meter. I have two different
units -- an E and a GL model. Both work fine and
have calibration stickers.

400 GL
This unit is extremely sensitive with a 100 microvolt
mirrored scale and ranges from .1mV to 1000V full
scale (-80 to +60dBm), with a log scale. It also has
a switchable 100 kHz low pass filter.
This one works like it should, and includes paper
work for $125.

400 E
This unit has ranges from 1 mv to 300 volts full scale
(-60 to +50 dbm), with a linear mirrored scale. No low
pass filter.
This one works fine and has paper work for $75.

HP 5306 A, Precision DMM and Counter:

The HP 5306 A is a precision 4 1/2 digit digital multi
meter and counter combination unit. This is a lab
quality precision instrument. It is not a very high
precision, $10,000 unit, but is right below that category.
It is much better than the standard "bench" meter. It
measures DC and AC voltages to 1000 V (AC frequency
response from 40 Hz up to 100 KHz), and resistance to
10 Megs. Input impedance is 10 Meg, with extremely
high (over 80 db) Common Mode Rejection Ratio.

It also has a built in frequency counter, as an added
bonus.
It is in a metal, shielded, enclosure, and is powered by
120 V AC.

This one works 100% with really great accuracy. It looks
extremely nice.
Paper work is included for only $200.

HP 3476 A Digital Multi Meter:

The HP model 3476A is a 3½-digit instrument that
measures dc and ac volts, dc and ac current, and
resistance. It has autoranging and autopolarity
selection but it also has a range-hold function that
retains a range regardless of input changes. Note that
it measures AC currents, which many do not measure.

Full-scale ranges are from ±0.110V to ±1000V dc and
ac, ±0.110 to 1.10A dc and ac, and 1.10kΩ to 11,000kΩ.
The frequency range for ac voltage and current
measurements is 45Hz to 5kHz.

This is a very high quality DMM for the bench.
It has a calibration sticker on it (that is out
of date), which shows the quality of this meter.

This particular unit works as it should, although
there is a segment of the LED readout that is out,
but this does not detract from its accuracy and
usefullness. It is in very nice cosmetic condition.

With paper work for $120.

I also have many other accessories available such as many
different types of microphones, HTs, VHF and UHF rigs, HF
and VHF/UHF antennas, connectors, miscellaneous accessories,
etc.
Just too many to list here. Please e-mail your requests.

Prices do not include shipping from Florida.

Thanks.
