I have downloaded the Driver of Agilent 4155B from NI website. However, when I used the sub-vi “Op-Download Trace.vi” in the library, I found only limited kinds of traces can be read from 4155B.
I use REAl 64-bit length data transfer format. When the trace is successfully read, the “read buffer” of” VISA read” function is like Figure 1.
HOWEVER, all the other kinds of trace cannot be read. When I send query command to get other data variable values, the “read buffer” of” VISA read” function is like Figure2.
Can some kind people help me to get the values of other kinds of traces?
Thank you for reading and answering.
Best regards from Liverpool.

In the Programmer's Guide of Agilent 4155B Analyzer, it only shows the instruction as the screenshot below.
It does not talk about which traces can be read and which traces cannot. However, in the example it gives, the trace read is the current of primary source (VAR1) which is one of the limited traces can be read from the Agilent 4155B as my post.

Thanks for your information. But I cannot find what you said in the User Manual. Could you tell me which section it is (which page it is)? Because I need mention it in my Thesis.
Thank you so much.
