CALCulate:FMODel:ISD<Ph_pt>:COUPon[:STATe] <Boolean>
For a fixture modeling with the ISD tool, this command allows to specify the ports to
which the test coupon is connected.
This has to be defined before measuring the test coupon (using CALCulate:FMODel:
ISD<Ph_pt>:COUPon:MEASure or CALCulate:FMODel:ISD<Ph_pt>:COUPon:
MEASure:OPEN and CALCulate:FMODel:ISD<Ph_pt>:COUPon:MEASure:SHORt
).
Suffix:
<Ph_pt>
.
Physical port number
Parameters:
<Boolean> 1 (ON, true) if the test coupon is connected to port <Ph_pt>, 0
(OFF, false) otherwise
Example: See Chapter 8.2.8, "Fixture modeling", on page 1628
Manual operation: See "Active" on page 677
CALCulate:FMODel:ISD<Ph_pt>:DCEXtrapolat <Boolean>
Defines whether the de-/embedding file generated by the ISD tool contains (extrapola-
ted) DC data.
Can only be set to ON, if a recent version of the ISD tool (from 2019-12 or later) is
used. ON correspons to add_dc=1 in the tool's batch mode.
Suffix:
<Ph_pt>
.
This suffix is ignored.
Parameters:
<Boolean> OFF (0)
No DC data added, i.e. the touchstone data reach down to the
start frequency of the instrument sweep.
ON (1)
The ISD tool adds (extrapolated) S-parameter data for f = 0.
*RST: OFF (0)
Manual operation: See "DC Extrapolation" on page 685
CALCulate:FMODel:ISD<Ph_pt>:DUT:MEASure
For a fixture modeling with the ISD tool, this command allows to measure DUT + Fix-
ture at the active ports (see CALCulate:FMODel:ISD<Ph_pt>:DUT[:STATe])
Suffix:
<Ph_pt>
.
This suffix is ignored.
Example: See Chapter 8.2.8, "Fixture modeling", on page 1628
Usage: Event
Manual operation: See "Measure" on page 678
