Mike, I believe that is the same HP training video that is presented John Higham. It is available on YouTube as a four part series titled "HP 8920A 8920B RF Communications Test Set - 1 of 4"

Is there any way to link the posted files to the discussion in which they were associated? Thanks, Mike

Greetings to all, I recently acquired an HP8920A and was looking for an Epson HP 11807A,E Option 001 card. After searching the internet I am not finding anything. Are these cards still available anywhere? Andy

I would LOVE a copy of this... -------- Original message -------- From: W6KX <w6kx@...> Date: 2/7/24 8:02 PM (GMT-06:00) I have an HP produced demonstration video which includes usage of the11807A NA FM tests.

Here it is - https://fasma.org ? wp-content ? uploads ? TIA-603-E-1.pdf

The automated test routines that you can run are useful. If you don't have the software, or you want to learn how to do it yourself, the standard "TIA 603-D-2010" will tell you more than you wanted to know. That document is difficult to obtain. Here is a simplified document that walks you through the tests. Harris makes this freely available, and even gives you a hard copy when you take the class.

I'm hoping someone with knowledge about using the 11807A NA_FM tests Option 001 card can provide some advice. Several of the TX tests; namely; Test 4 TX Modulation limiting, Test 5, TX Audio response and Test 6 TX Audio distortion all fail with a message "Deviation would not set to 3 kHz" Looking through lots of documentation I can't find any reference to this fault message.

Hi all... This is a weird one... I have been servicing HP8920's / 8922's for years for a radio shop but this one is above all... HP8920, option 011... When connected to a 25W or less transmitter, the rf power display is excellent (particularly for a test set of this age!), but as soon as I use a radio above 25-30 watts, the display goes completely out of this world. Power levels of about 1500000 watts, 92 dBm, or 9000 rf volts!!! All scales seem to correlate with each other but with an incomprehensible +47 dB offset!!!! Suddenly, when RF drive rises from 25 watts to 30 watts, no glitch, no warning, from 30 to 1500000 watts! Outside of that offset, everything else is ok. Rock solid OCXO, generate levels, audio... Only this rf power offset!!! In [BLUE] [CONFIG], all rf offsets are at 0 dB. Has anyone ever seen such a behavior? One thing sure: HP engineers had real fun designing a radio comm test set able to display over 1 megawatt!!!! 73 de Normand VE2UM

Greetings all, It looks like the power supply in my 8924C has died. The green light does not even come on. The fuse is ok. Any ideas? Is there anyone out there repairing them as I cannot find any info on the supply. Any help is greatly appreciated. Thanks, Mike, WA9FDO

These are duplicates that I don't need. I haven't tried every one of the programs in my HP8920B, but the ones that I did seem to work fine. It looks like the EDACS tools also does conventional channels. NOT FOR HP8920A - DIFFERENT TYPE OF CARDS. The Flash card is a SMART 4 MB that contains these HP tools: HP 11807: Opt 001 - NA FM Tools, Opt 003 - AM Tools, Opt 011 - EDACS Tools, Opt 100 - RF Tools The card is formatted to about 2MB, as when formatted to 4 MB, my HP8920B didn't recognize it. If I remember, years ago when this was hosted on Yahoo, someone posted a few minor mods to make some of these programs work on the HP8924. That's for you to figure out. The SRAM card is a SMART 256KB with internal rechargeable battery. Not sure how long it will hold a charge, as it is used. Stick it in your HP to charge it once in a while. An SRAM card is useful to store your programs and data. You can't (easily) write to the Flash card. $50 for both cards, including USPS Priority Mail shipping.

Hi all, I am looking for the A5 Serial I/O PCB No. 08920-69129, and the A7 Controller PCB No. 08920-69107. My AF-Diags tell me they are faulty. All else seems OK. Any comment or assistance would be appreciated. Regards Bill M. VK6IC

Happy Holidays to all group members I am a proud new owner of an HP8920A. My main use will be for various amateur radio applications. I have been reading as much documentation as I can find on the internet. I am amazed by the capabilities of this instrument. The IBasic compiler offers some intriguing and creative possibilities. Has anyone developed useful IBasic programs for the 8920A?

Hi , I have a spectrum analyzer HP8920a and during the self test RF DIAG I have the message "VCO 1Ghz Not locked". I checked at the board A15 and I have made some measurements. The output of the divider by 50 (signal 10_PLL10 pin 11 U10 and pin2 U27) is not working; there is no signal. At the entry of the divider by 50 the 500MHz signal is correct. The problem is the schematic in the user manual is different from the board. In the user manual the divider uses U27 MC1201 and U18 MC1038, and on the board there are U27 74AC191 and U18 "1820 8762". I try to find some datasheet about this circuit 1820 8762 I don't find anything on the web. For the 74AC191 no problem; I have the datasheet. To test the board I just put the power supply voltages +12V, -12V, +5V on the P2. In that manner it's possible to easily test the board A15. So my PLL is out of lock because it's missing the signal "10_PLL10" pin 11 of U10. Has anyone ever encountered this problem? If someone has the datasheet of U18 "1820 8762" and the schematic of this divider by 50, it would be nice. Thank you for your help. F4EYM.

Due to a combination of several posts needing either editing and/or me emailing the poster to establish clarity, there has been more than a day to get them posted. I've been very busy with several high priority projects so haven't been able to email the posters in question individually, but with this notification they will know now what's going on. Hank

Hi James, Lots of clever things in these instruments. One I found very useful in fault finding is the TEST Button. That opens a screen to select the ROM part of the memory where the test programs reside. There are the choices of AF-Diag RF-diag MS-diag. Once you have selected which type of diagnostic test you wish the run, use the control knob to select, Cursor Up / Down, and Select, to select the test required. Then move the cursor to Run, which actually loads the little program in the unit, from that you cursor down to select which test to run. Push the control knob to make the test start. If you select the "All test", it will run all the list one after the other until it gets to the end, where you should see "NO Failures". Do each test either one at a time or step by step until you get no failures. Carefully read the screen and follow any setup instructions like connecting the Audio out at the back to the Audio in at the front, etc. You cannot destroy any data, so don't be worried about that. Play with these tests and try each choice; some allow you to do step by step and to pause on error. This is great for locating the section that has a problem. Make sure you exit the tests and return to main screen before you turn off the power. I make notes so if I get interrupted (by the missus or the phone), I can get back to where I left off. I think the Spec Analyzer is one of the plug in modules at the back near the power supply. Check if you have any OOL leds on (Out of Lock) that are in those modules. That could be a clue as to where the problem is. Be very careful in plugging in the boards and modules. It can be easy to bend the pins on the mother board. Have fun James. Bill M.

Hi Bill, Thanks for reply. I didn't change that battery and I measured it and it was 2.9 V. It's very weird that everything goes normal except Spec Ana. That error message only pops out when accessing the Spec Ana. Regards, James
