Measurement
source is not Internal trigger, you must trigger the instrument after issuing the command.
To define the OPEN and SHORT compensation standards using the commands described
so far, follow these steps:
If you use the same standards for both impedance and R
dc
measurements or you omit
R
dc
measurement:
Step 1. Connect the OPEN standard and then issue the :CORR2:COLL command, which
designates “STAN1” as the parameter. If the trigger source is not Internal trigger, you must
trigger the instrument after issuing the command. This applies to step 2 as well.
Step 2. Connect the SHORT standard and then issue the :CORR2:COLL command, which
designates “STAN2” as the parameter.
Step 3. Issue the :CORR2:COLL:SAVE command.
If you use different standards for impedance and R
dc
measurements:
Step 1. Connect the OPEN standard for impedance measurement and then issue the
:CORR2:COLL or :CORR2:COLL:RF command, which designates “STAN1” as the
parameter. If the trigger source is not Internal trigger, you must trigger the instrument after
issuing the command. This applies to steps 2 through 4 as well.
Step 2. Connect the SHORT standard for impedance measurement and then issue the
:CORR2:COLL or :CORR2:COLL:RF command, which designates “STAN2” as the
parameter.
Step 3. Connect the OPEN standard for R
dc
measurement and then issue the :CORR2:COLL:DC
command, which designates “STAN1” as the parameter.
Step 4. Connect the SHORT standard for R
dc
measurement and then issue the
:CORR2:COLL:DC command, which designates “STAN2” as the parameter.
Step 5. Issue the :CORR2:COLL:SAVE command.
