HElP: SCPI commands not supported by instrument

[huskerli]

Hello all,

I am actually writing my own drivers right now. I want to use PULSE to do some measurement,but I just found out this SCPI command I am using

":SOURce[1]:FUNCtion:SHAPe <DC|PULSe>" is not supported by the instrument. 

What should I do?

Thanks

Use a command supported by the instrument or use a instrument that does support the command.

I have no idea what instrument you are trying to use or where you got the command. Both of those are important details.

The instrument has the ultimate say. If the command is not supported, it is not supported. I don't know what you expect we can do about that.

I am using Agilent B2901A and I get the command from the Agilent B2900 Series SCPI command reference page 325.

I just do not get it since the instrument has that functionality and I been manually tested successfully why there is no SCPI command for that?

I think I must missed something really important and wanna someone who know this can points out me

Do some basic troubleshooting. Open a test panel in MAX. Go into the pulse mode manually. In the test panel, query the shape function. Write that down. Manually change back to DC. In MAX, send the command you think should work. Look at the instrument to see if it changed. If not, do an ERR? query in MAX. Write those results down. Post back with the results.

Looking at the docs you provided, this command is listed under Conventional commands not supported by B2900. So I guess this function is not supported.  If an equivalent command exists, you will have to find it in the docs you provided.  You may have to experiment a little.
