Test Coupons > Insertion Loss
Tells the ISD tool about the linearity of the 2xThru test coupon:
●
"Linear": Linear insertion loss
●
"Non-Linear" (default): Non-linear insertion loss
●
"Resonant": The 2x Thru test coupon is split and used directly for deembedding
This option can be more accurate if the fixture and the 2x Thru have the same
impedance at every location.
Remote command:
CALCulate:FMODel:ISD:ATTenuation:BEHavior
Lead Ins
Defines how the ISD tool interprets the lead-in data.
Scaling for attenuation ← Lead Ins
Scales the test coupon's attenuation.
Default is 1.
Remote command:
CALCulate:FMODel:ISD:SCALe:ATTenuation
Scaling for flight time ← Lead Ins
Overrides the lead-in's flight time (i.e. its delay) in case the through-trace test coupon
is a bit too short or too long.
Default is 1.
Remote command:
CALCulate:FMODel:ISD:SCALe:FTIMe
Auto. flight time for DUT + lead-Ins ← Lead Ins
If checked (default) the flight time for DUT + lead-ins is calculated automatically. Other-
wise it can be specified manually (see
Remote command:
CALCulate:FMODel:ISD:FTIMe:OVERride
DUT + lead-ins flight time ← Lead Ins
Allows you to set the flight time for DUT + lead-ins manually, if
+ lead-Ins
Set the value manually, if the "DUT + Test Fixture" does not have a Through response
and the total flight time exceeds 10ns.
Remote command:
CALCulate:FMODel:ISD:FTIMe:DUT
DUT With Fixture
Defines how the ISD tool interprets the "DUT + Test Fixture" data.
Port Sequence ← DUT With Fixture
Tells the ISD tool about the arrangement of "DUT + Fixture" ports:
●
"1 to N on left": Ports 1 to N are on the left and ports N+1 to 2*N are on the right.
