Audio Precision system one THD vs Power (W)

[2N6658]

Hello,

I have a system one with DSP, Analogic Generator and Analyzer : SYS-222, runing with APWin and PCMCIA card. Selftest is OK.

- Is it possible to make a sweep : THD (or SINAD) vs Power (W) ? I can't find anyway to do that...
- What means a white "R" on the top of a graph, sometime on all the graph, some time just in part of it ?

Thanks.

The attached test "pwr.txt" rename to "pwr.at1"
Load the attached renamed test. it is in GENMON mode and you need to select LOAD Z, and GEN AMP.

Hello Duke,

I have a pb : when I try to load your test, I have the message :
"Error (9091) : Can only import version 2.10 or 2.00 S1.EXE test files"

Thanks for help.

Well I assumed you were using ApWin 2.24 Not DOS. You can Download ApWin, install it and run it is DEMO MODE. Load the test and copy the panels settings (Screen capture) then open AP DOS and set the DOS PANELS to match.

Or switch over to ApWin instead of S1 right away.
It is a free download from ap.com if you register.

I use ApWin 2.24, but I've done a mistake : I go in "File", then "import", and there is only "S1.EXE Test", that's why I have an "Error message".

So how can I load the test file Duke send (pwr.at1) under ApWin ?

I don't know very well AP sys one with ApWin, I have it juste two weeks ago...

Thank for your help.

Hello,

In fact it's quite easy : on sweep panel you must choose "data 3 on x asis" as data 3 is the level in Watt, and it works fine ! 🙂
