The notation for ratios follows the usual scheme of the vector network analyzer:
●
The a-waves are the outgoing/transmitted waves at the analyzer's test ports.
●
The b-waves are the incoming/measured waves.
●
The source port for the stimulus signal must be specified in addition.
●
The port number range covers all test ports of the analyzer.
Numerator
Selects the type (left pull-down list) and the port number assignment (right pull-down
list) of the wave that forms the numerator of the ratio.
Remote command:
CALCulate<Ch>:PARameter:MEASure "<Trace_Name>", "B2/A1" | ...
CALCulate<Ch>:PARameter:SDEFine "<Trace_Name>", "B2/A1" | ...
Denominator
Selects the type (left pull-down list) and the port number assignment (right pull-down
list) of the wave that forms the denominator of the ratio.
Remote command:
CALCulate<Ch>:PARameter:MEASure "<Trace_Name>", "B2/A1" | ...
CALCulate<Ch>:PARameter:SDEFine "<Trace_Name>", "B2/A1" | ...
Use Generator as Source
If selected, the "Port" control lists the external generators. Otherwise it lists the ana-
lyzer ports.
External generators must be configured explicitly in the "External Generators" dialog
before they appear in the list. See also Chapter 4.7.39, "External generators",
on page 290.
