Manual HP 5302A Frequency Counter
Gerard Tel
Does anybody have a user manual for the Hewlett Packard
5302A Frequency Counter?
Does anybody know when this unit was sold or what the
specified accuracy is?

The 5302A was still for sale in 1983 (my catalog date). Basic Specs:
5300A and 5300B Measurement System Mainframe
===================================
Time Base
Standard Crystal Frequency: 10 MHz
Stability
Aging rate: <3 parts in 10**7/mo
Temperature: < +- 1 part in 10**6, 0 deg to 50 deg C
Typically: <+- 2 parts in 10**6, 15 deg to 40 deg C
Line Voltage:
5302A 50 MHz Universal Counter Module
===================================
Range : Channel A 10 Hz to 50 MHz; Channel B 10 Hz to 10 MHz
Sensitivity (Min): 25 mV rms sine wave 50 Hz to 1 MHz, 50 mV rms sine wave
10 Hz to 10 MHz. 100 mV rms sine wave at at 50 MHz. 150 mV p-p pulse at
minimum pulse widith, 50 ns.
Trigger level: selectable positive, negative, or zero volts.
Hope this helps,

I have a manual for this, but it is not for sale. If you have specific
questions I can probably answer them.
After calibration, these are usually within 0.4 ppm after 30 minutes
warmup. The accuracy is a function of the crystal clock in the 5300A/B
display and these displays drift up (age) 0.1-0.2 ppm/year, making
their readings go low at about that rate. These are rather old now, so
the aging rate has significantly slowed down. They are nice counters.
I have several of this series (5300-5312) for sale.
I believe they were sold from the early 70s to the early 80s.
