Measurement

SCPI.CALCulate(Ch).PARameter(Tr).DEFine

Attribute	Detail
Object Type	Property (read/write)
Data Type	String
Target	Trace Tr of channel Ch, Ch: channel number 1–16 (see Table 1 on page 25) Tr: trace number 1–16 (see Table 3 on page 33)
Description	The measurement parameter of the trace.
Allowable Values	"S11" : S11 parameter "S21" : S21 parameter "S12" : S12 parameter "S22" : S22 parameter "A" : Receiver A "B" : Receiver B "R1" : Receiver R1 "R2" : Receiver R2
Out of Range	An error occurs. Error code: 208.
Preset Value	Depends on the trace number. Tr 1, Tr 5, Tr 9, Tr 13: "S11" Tr 2, Tr 6, Tr 10, Tr 14: "S21" Tr 3, Tr 7, Tr 11, Tr 15: "S12" Tr 4, Tr 8, Tr 12, Tr 16: "S22"
Syntax	Dim Meas As String Meas = app.SCPI.CALCulate(Ch).PARameter(Tr).DEFine app.SCPI.CALCulate(Ch).PARameter(Tr).DEFine = "S11"
Equivalent Softkeys	Measurement > Measurement > S11 / S21 / S12 / S22 Measurement > Measurement > Absolute > { A(1) / B(1) / R1(1) / A(2) / B(2) / R2(2) }
Table 3. Tr: Trace Number
Data Type	Long
Description	Trace number
Range	from 1 to 16
Out of Range	An error occurs. Error code: 202.
Notes	If the trace number is not specified, it is taken as equal to 1.
