●
"Ports on right": skip the ports on the right (according to the selected port
sequence)
●
"Manually set ports": use
to define the ports to be skipped
Remote command:
Ports to Skip (manual) ← DUT With Fixture
If
is set to "Manually set ports" this allows you to define the ports to be
skipped. Enter the port numbers, separated by blanks (e.g. '1 3 4').
Remote command:
CALCulate:FMODel:ISD<Ph_pt>:PORT:SKIP
Calculations
Some additional parameters that define how the ISD tool calculates its output.
Enforce Passitivity ← Calculations
If checked (default), the ISD tool enforces passivity and reciprocity for the test coupons
and the test fixture.
Remote command:
CALCulate:FMODel:ISD<Ph_pt>:PASSivity
Trace Coupling ← Calculations
Tells the ISD tool about coupling among lead-in traces
●
"None": no coupling.
The ISD tool optimizes odd- and single-ended insertion losses.
●
"Weak": coupling is extracted even if there are 2 ports enabled on the test coupon
●
"Strong" (default): if the test coupon is a 4-port file, and there are two ports to be
extracted, the ISD tool optimizes odd- and even-mode insertion losses.
The ISD tool automatically reverts to "Weak" if these conditions are not met.
Remote command:
CALCulate:FMODel:ISD<Ph_pt>:TRACe:COUPling
Operation (fast/acc) ← Calculations
Influences the speed of execution and accuracy of the ISD tool.
●
"Accurate" (default): normal execution mode
●
"Fast": reduces the execution time to ~50%
Often this mode can be enabled with only little loss of accuracy.
Remote command:
CALCulate:FMODel:ISD<Ph_pt>:OPERation
Max Freq to Deembed ← Calculations
When the test coupon’s return loss is not less than the insertion loss, the maximum fre-
quency to deembed together with the proper
setting gives the best accu-
racy.
By default, the maximum frequency is set to the maximum frequency the VNA can use.
