Hi Experts,

I am unable to get data from trace A/R1 in matlab. I set up two traces and aquire data as mentioned below:


I create trace A/R1 and B/R1 from Network Ananlyzer and than confirms the name of traces using CALC: CAT? command, which returns the name of traces and than I uses below commands from Matalb using those names returned from Network Analyzer.

Trace Setup

'CALC: PAR: SEL ''CH1_A/R1_1"'

'CALC: PAR: SEL ''CH1_B/R1_1"'

Store Data

'MMEM:STOR:TRAC:FOR:SNP AUTO'

Read Data

'CALC:DATA:SNP ? 1'

All this is done in using Matlab.

Now, what i get in matla is as below:

It contains only three data which is :

1. time or frequency information
2. Magnitued for first trace A/R1
3. Phase for first trace A/R1

No information is available for B/R1, i need magnitude of both A/R1 and B/R1.

Please help me.

Thank You.
