Re: HP-8753E Option Key Installation Failure
Rich, There is nothing wrong with just reading the contents of the EEPROM. Then store the original safely and program another one for a test. I¡¯ve done that a couple of time for spectrum analyers.

Re: HP-8753E Option Key Installation Failure
Leon: That is good information. In a little while, I am going to test my S400 Jumper to make sure when I toggle #8 on the dip switch, I am getting continuity. The idea of having to pull the EEPROM and

Re: HP-8753E Option Key Installation Failure
Hi Rich, I've done an option upgrade 14 days ago on my 8753D (with the CPU 000 board, which is probably also in your VNA). I've got the same error, because I did not flip the jumper (there is no A9

Re: Help E4402B 1DR Option not working
Funny you should raise this as I was just yesterday trying to get my E4401 with the same option to less than 1KHz to try and have a look at the spectral purity of a 8640B.?It would not go below 1KHz

Hi Andrew: Yes, I am not sure what is going on. I was told this usually is a pretty straight forward process. The analyzer is not failing any of the self test. I think tomorrow I am going to measure

Re: 11710B Down converter
you may be able to cross it over to a PN2218A.?? Some 2N numbers in a T0 style can cross over to an epoxy package by replacing the 2N with a PN. Harvey

Re: HP-8753E Option Key Installation Failure
If the serial numbers match, and you still get the fail message, I wonder if that indicates there's actually a hardware problem with your analyser and it can't complete the self-cal properly. These

Help E4402B 1DR Option not working
I have an E4402B that shows options 1DR installed, but it doesn't seem to work as no BW smaller than 1 kHz can be selected. See picture. What can I do to address this issue? Thank you and Best,

Re: 8566 5.2V supply
A bit of a late reply, but I hope it is still of value. The 1854-0441 was used as Q4 on the A17 boards for instruments with serial number prefixes in the range 2410A to 2532A. It is a general purpose

Re: HP-8753E Option Key Installation Failure
I believe there's a jumper or a dip switch that has to be set correctly to allow the eeprom to be written. The instructions are in the service manual. [email protected]> wrote:

Re: [HP-Agilent-KI eysight-equipment] FM Tuner alignment generator?..
The 8640 can deviate 10.7 if you mix it down with e.g. the 11710 Down Converter. Or even any generator and a mixer; there¡¯s an app note for that, AN171-2. Dave Wise Sent: Thursday, February 10, 2022

To do a comprehensive job of aligning FM tuners you really want a generator designed for that job - especially if you want to verify or align FM stereo multiplex decoders. One example of a relatively
