Agilent 8722ES Option 400 - Switch Terms

Hi,

I’m developing a driver for the older Agilent 8722ES for VNA Tools (http://www.metas.ch/vnatools) . And I’ve one question regarding switch terms.

I want to measure R1/A (a1/b1) when port 2 drives and R2/B (a2/b2) when port 1 drives. I use the following commands:

CHAN1;AR;CONV1DS;TSTPP2;AUXCOFF;CHAN2;BR;CONV1DS;TSTPP1;AUXCOFF;DUACON;SPLID2

But this measures R2/A when port 2 drives and R1/B when port 1 drives. I can’t find any command to select which R receiver (independent of the source position) I want to measure.

Or in other words I can't find a way to switch the ‘TRL CAL’ switch, see http://literature.cdn.keysight.com/litweb/pdf/08720-90397.pdf page 164, A9 Source Control Board.

Thanks in anticipation

Regards
Michael
