OWON XDS3102A SCPI LAN

[y33t]

Hi everyone,

I am trying to com with a scope over LAN that supports SCPI. Link is established I can ;

*RST *CLS

but I can't do ;

:MEASure:SOURce CH1

it returns zero. To be more clear ;

a = SCPI(host, timeout=0.5)
a.ask('SYST:ERR?');
a.write('*RST'); a.write('*CLS');
a.ask(":MEASure:SOURce CH1");

returns ;

>> SYST:ERR?
<< 
>> SYST:ERR?
<< 
>> :MEASure:SOURce CH1
<< 
>> SYST:ERR?
<< 

doing *IDN? retuns successfully.

Hi, I'm not familiar with Owon remote control but I have noticed two things:
-the  "a.ask(":MEASure:SOURce CH1");" should be write command, it is not going to return any value as it will setup the measurement source.
- inside brackets you used " and ' there is probably a huge difference in your programming language.
