Do you maintain a list with an overview of all known hardware and software problems?

In this list you can each time add new problems and also indicate which problems that are solved.

You can give each problem a title, and classify it as a hardware problem, a software problem or a combination of both.

You can indicate in which hardware revision, and/or software revision the problem has been solved.

When customers order a product on your webstore, you can indicate which hardware revision and which software revision they will get. This avoids discussions later on, as the customer will know upfront what he will get.

Good luck in fixing all your hardware and software problems! :)

thank you so much for your advice , it is good idea.
but we did not make a record . because those problem is small problem, don't affect normally using , so we did not record those .
thank you again
now we have update all those small problem.

Hi, everybody.
Probably this is some kindof side topic but important.

I would like to make my own program to control JDS6600 (surely specific and simpler than standard), where I can find commands description for JDS? Pls. help.

Another question (JDS is new for me) for sweep frequency mode: is there any syncro signal when JDS starts  change frequensy, how to get it?

Thank you in advance

Hi tritutik,

I found a PDF of the command protocol on the included CD. It's in Chinese, so you may have to use Google Translate if you can't read it.

(I tried to copy the filename here, but the Chinese characters didn't come through. If you look in the Chinese folder, you'll see a subfolder with some PDFs in it. The comm protocol PDF is the smallest one, about 288kB.)

Hello,

I have a fairly newb question here. I am using the JDS6600 for lab experiments in the Art of Electronics Student Manual (Hayes/Horowitz). For Lab 2 (Low-pass Filter), the manual suggests,


--- Quote ---As you measure phase shift, use the function generator's SYNC or TTL output to drive the scope's External Trigger. That will define the input phase cleanly.
--- End quote ---

I am assuming this means that a function generator with SYNC/TTL output generates a pulse at the very beginning (0 degrees) of a waveform, which in turn could be used to trigger the sweep on the scope.

Does the JDS6600 have such a feature? I see a reference to the "TTL extension interface" in the manual, with signals TTL1 and TTL2, but no explanation of their function or usage. Are these signals equivalent to a "SYNC" output?

Thank you,
caned
