Great video. I just received an 8093B this week. I ran through the operational checks in the manual, and it appears to be fully functional. These are amazing instruments. I’ll have to check out the software.
Hello there, Very informative video! Can you tell me how do you phisically connect the feed from the dummy load into the 8903? Do you float the input on the analyzer? Do you use both conductors of the BCN cable or disconnect the shield? Thanks!
The connection from the dummy load into the 8903 is direct wire. The shield goes to the negative (outside) side of the BNC connector and the center wire goes to the hot side of the dummy load. It is important to observe this connection because nowadays most everything has its negative side, including the 8903, connected together thru the safety ground of the AC power plug. It is probably best not to float the equipment from the safety ground. I don't remember the max voltage input to the 8903 but it is pretty high as I have measured the output of 1300 watts across 8 ohms (102 volts RMS) and it is within the voltage margins of the 8903.
It will work for bridged output assuming the output stage of the amplifier permits bridging. I am sure you know that some transformerless transistor amplifiers can not be bridged.
Sorry for being late to the party, but could you please explain the connection of the output of an amp under test to the 8903 a little bit more in detail? I can't get my head around the correct way to connect an output from an DUT to the 8903B. It would be absolutely terrific if you could help a novice with your knowledge. Thank you. And, of course, thank you for all of your effort to produce very good and informative videos.
If you have a full Adobe publishing software, you can set that as your default printer and when you select print from Pete's software, it will generate the graph in a PDF format. There are also freeware PDF programs that will do the same if you don't have full Adobe software. Otherwise, like David said, Print Screen into your software of choice.
Hi - did you have some other vids up of the P.Millett & HP8903? I'm sure you had one that helped me finally figure how to configure things, but can't seem to find it now.. was it deleted?
Nothing has been deleted. I have three or four posted. The easy way to get a catalog of all my videos is go to www.elpasotubeamps.com and you will see them all listed. They were posted a year or so ago. I am glad they have helped you.
I don't know. If it has that same adapter, then it might work as I assume Pete's software is written to communicate with the HPIB adapter also known as the GPIB adapter - they are the same thing - maybe you can ask Pete Millett.
It can be a challenge to get it to work but it is worth the effort. I don't know of any particular stumbling block except to don't forget to save the settings. That bit me for a couple of days... I have other videos on this installation and configuration that might help. Good luck - I am sure you will figure it out. Here are two more links that might help. ua-cam.com/video/4KngW_wAVZ8/v-deo.html ua-cam.com/video/_FtJh3N4FK0/v-deo.html
John, just guessing, but did you name the Instrument (the 8903) "Audio Analyzer" (without the quote marks, of course) in the VEE Instrument Manager? Or can't you see the 82357A in the Instrument Manager? If "Find" doesn't work, just add it manually with Name: "Audio Analyzer", the VISA Address GPIB0::28::INSTR and you should be good.
it is called HP (or Agilent) 82357B. Here is a link to one on Ebay for reference. www.ebay.com/itm/Agilent-82357B-USB-to-GPIB-HPIB-Interface-Adapter-For-8163A-8163B-8164A-86100A/112054450762?hash=item1a16f73a4a:g:UqQAAOSw8cNUR04W:rk:2:pf:0
It is called a GPIB or HPIB (same difference) to USB interface. The model number is 82357B and can usually be found on Ebay.

Hi David great video its nice to know how Pete Millett software works thanks for the posting.

Thanks for your reply. So this would work for both - standard output configuration and BTL outputs?

CAN THIS SOFTWARE BE USED FOR THE PANASONIC VP-7722A ?
I don't know. If it has that same adapter, then it might work as I assume Pete's software is written to communicate with the HPIB adapter also known as the GPIB adapter - they are the same thing - maybe you can ask Pete Millett.
@@ElPasoTubeAmps Thanks
I have an 82357A interface and Runtime 9.3 installed, cant seem to get it configured correctly, getting the question mark

What type of GPIB did you use? I saw the usb but I was under the impression that it only worked with pci and isa.

Hi What interface are you using with the 8903? You mentioned it was USB. ?Thank You

dont let the city inspector see your high voltage sign, it it was me city would make me pay kinda like the Taxman(beatles)
