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. |
