One more thing - depending on the microwave counter used, and it's signal kickout, it may add some spurs to the displayed signal. There's not much isolation on the 1LO port. If anything looks

Hi Chuck, Are you saying that you can clean the switches with IPA without taking the keyboard apart or removing it from the instrument? Do you just spray it in along side of the keys? I have an HP

You can measure the first LO YTO frequency - hook up to the LO output on the front panel. It runs from about 2-4 GHz. By keeping track of the 1LO, n - the harmonic used, and the first IF - 2050 or 550

By source, I mean an online respository such as the HP/Agilent Test Equipment Group Files or similar were I (or others) could access them to use them with a used E2423A that doesn't include the disk.

Hi, I have had experience with the SimmConn Labs CRT to LCD Replacement kit. I put the 6.5 inch LCD into my HP 8566B. It is an AWESOME DISPLAY. Different Color Schemes, everything is better, weighs

By "source" do you mean the contents of the floppy or the source code that created it? I had the floppy (but I've misplaced it). However I have the files in a directory on a 16500B hard drive. I don't

I agree. I have replaced the CFL’s in my 8753E and 8720D, and it was pretty easy. They’re not very expensive on *Bay either. I’m also considering doing an LED conversion next time around. Daun

Regarding the HP E2423A SCSI Bus Preprocessor Interface: Does anyone know a source for the files on the disk that came with the E2423A that has the seven Inverse Assemblers? (ISCSIDIR, ISSISEQ,

If the display is dim, there's a good chance the CFL lamps in the display are at EOL. If a new display is not available, there's not a big deal for a handy man to replace the CFL lamps with

Hello All, I am looking for the battery adapter for the E4411 spectrum analyzer. This is a small part that screws to the back of the spectrum analyzer and makes contact with the battery. The part

Joe, interesting, the reason I found this problem was that I was implementing a more modern version of AN 286-2: http://www.hpmemoryproject.org/an/pdf/an_286-2.pdf The 61.0 function resets the listen

Dear Dr. David: The original LCD for 8753E are SHARP LQ9D340H , it is still available somewhere ? RegardTony CheungFEB 25 2016 To: hp_agilent_equipment@... Sent: Thursday, February 25,

Mu metal performance is similar to that of ferrites on higher frequencies and powdered iron above that into the VHF region. They all contain the field due to the magnetic properties of the material

Thomas, Yes, the GPIB is fully functional on my 8902A. I use it for testing of various signal generators, including the 8642B. This specific generator has built-in GPIB intelligence for controlling

I have both an 8720D and an 8753ES. Both are LCD, but the displays are rather dim. I see a VNA in eBay which was advertised as having a brighter replacement LCD. Does anyone have any experience of

Thanks, David - great advice! I'll start planning by making a drawing of the A9 board changes and then acquire the necessary parts. I'll let you know how things progress. Best regards, Joe, KN5U

I have advocated washing the assembled keyboards with 91 or 99% IPA before on this board. It changes the character of the keys from something that feels like you are going to do damage, to something

This is most interesting, thank you for the help! 2 of 3 instruments does not respond according to the manual. John and Joe, have you tried your instruments with GPIB? I suppose there could be a error

I do not think the reconstruction has to be that comprehensive. The MAR type devices have the same pinout except for one lead which is power on the stock amplifier and ground on the MAR amplifier.
