Agilent 53132A Counter Repair (FIXED and Upgraded)
<< < (6/29) > >>
HighVoltage:
The "upgrade" parts arrived from Poland and got installed today.
After turning on the instrument it gave the message "Not Calibrated", so it detected the 10 MHz OCXO alright.
The 3 GHz Pre-Scaler also seems to work.

Here are some pictures of the installed upgrades.
Next is to calibrate and check all specifications.

Hi,

I have replaced the noisy fan of my HP53181A with the following:  Sunon A40201V4 (Super Silence Series  :))
http://www.digikey.com/product-search/en?mpart=HA40201V4-000U-999&vendor=259

The fan is very quiet by itself  (12.8dB-A), but when installed, due to airflow & high rotation speed, it is still noticeable in a quiet environment.

Michel.

Thanks for the Digikey link to the fan.
I found a similar fan in Germany and installed it.
It is very quiet and in the lab I do not hear the noise of this instrument.

Calibration was too easy with a good 10 MHz source.
Instrument is finish now.

All done now.
Thanks to all that helped me with this one.

Is that fan strong enough, 5.5 cfm is not much.
