33120A Pulse Mode

[spider]

I am trying to configure pulse mode on Agilent 33120A using RS-232. I finally figured that the relevant vis on instrument driver does NOT support 33120A!!!

Have anyone got any ideas?

Does the instrument support pulse generation? It's not listed on the data sheet like it is for the 33210, etc..

I think the OP means "burst" or a PWM square wave.  33120A is a full featured AWG.  I've gotten tons of "pulses" out of 'em

I'm using it to generate a single pulse by using the square wave function in burst mode. Here are the commands that I send:

*RST; *WAI;*ESE 0; *SRE 0; *CLS; *WAI;
*PSC 0; *ESE 188; *SRE 32;VOLT:OFFS 0;
VOLT MIN;OUTP:LOAD INF;VOLT:UNIT VPP;
FUNC:SHAP SQUARE;TRIG:SOUR BUS;
BM:PHAS 0;BM:NCYC 1;BM:SOUR INT;
BM:STATE ON;PULS:DCYC 50;FREQ 6.25;

I then send a software trigger.

As Jeff said you can also use the ARB function (you then have to create the waveform shape that you want.

Yes, 33120A supports it. But, the vis in the 33xxx driver specifically mention that they can NOT be used with 33120A.

I need to configure the device as follows.

Freq = 1000 Hz

Amp = 1.5 V

Offset = 750 mV

Burst CNT = 5 cycles

Burst Rate = 100

Burst Phase = 0

Burst Source = Internal

Don't know why some smileys were inserted in the text.

 So here is a screenshot (sorry the the large size).

Don't worry.  Right now you cannot unescape smilies on the editor.  Laura F. is still working on forum upgrades.  How are they doing Laura?

the 33120A ishas been "Obsoleted" for about 5 years by Agilient.  Therefore newer agilient drivers will not "support" them.  Yet,  the 33120A is fully SCPI compliant so any AWG driver that uses SCPI MLM's will need only minor tweeks to support the 33120A command set.  Esentially you need to tweek range checking and the model name.

It should be pretty straightforward to add the burst function to the driver. No driver is 100% complete and as the download page states, it was tested with the 33210 and 33220.

If you modify the driver, you can post the changes to the IDN and hopefully they will get added to the next release.
