Stupid MSO4104 Question
« on: November 14, 2022, 07:08:44 pm »
I might being dumb, but I cannot find the answer in the manuals:
When I remote control the MSO4104 with my software, some command is disabling the front panel controls and only some of the buttons work.

It there a button to hold to regain local control?  Right now, I have to power it off and back on to get the front panel controls to work again.

I have to carefully trace through my program as one errant command may be corrupting the scope, but that's going to be a pain in the butt, but I am starting.  I was wondering if anyone knows a button to be held in to regain menu control.

If anyone is interested with the programming of the Tek scopes, silly things like this:

For the Tek TDS3000 series and TDS5404:
strProg = "TRIG:A:EDG:SLO RIS" is the command to set the trigger to Channel two Rising edge.

It also sends the MSO4104 in to lala land.  The MSO4104 wants:
strProg = "TRIG:A:EDGE:SLO RIS"

That f'ing missing "E" causes it problems.   Just about every other command from the TDS3000 series workes fine.

I love this MSO4104 but it can be aggravating as hell at times.  It's almost as it wasn't quite finished, marketed and sold and they never went back to fully clean up its code.

I did not try that, but thank you.

Any front panel buttons to get out of a lock state?  I'm not sure the front panel was locked but in some lala state.  Some controls worked (knobs) but none of the buttons.  I held everyone several seconds trying to regains control.  I had to power cycle the scope to regain control.

I think I found the command that was doing it and after adding that extra "E" the issue did not re-occur.  For the future, I think I will add and LED control (great fokes on the Visual Basic forum wrote a wonderful new control for that) to my various programs just to add an indication of the panel lock. 

With some instruments, like the Agilent E3632A Power Supply, I have to Assert Remote control for full control to work.  With the Tek Scopes, I do not do that and they work well.  In fact, I don't think the assert remote command even works with them (I would have to review).

The other tek scopes, if you send a bad command to them, they respond in kind, stating a bad command was sent.  The MSO4104 does also, unless the command is damn close, then it just goes in to lala land - lol.  Its brain locks as (as does mine when this happens).
