Combining different detectors
The detector setting in the More Ratios menu affects the ratio of a numerator and a denominator wave
quantity. This does not place any restriction on the measurement functionality of the analyzer, because
ratios can be formed by calculating the numerator and denominator individually and using the trace
functions. A possible application is the comparison of different detector settings for a particular trace.
Remote control:
CALCulate<Ch>:PARameter:MEASure "<Trace_Name>", "<Par>"
CALCulate<Ch>:PARameter:SDEFine "<Trace_Name>", "<Par>"
(the parameter name <Par> also contains the detector)

Wave Quantities
The Wave Quantities submenu selects a wave quantity to be measured and displayed.
•
a1 Src Port 1, b1 Src Port 1, b2 Src Port 1, a2 Src Port 2, b1 Src Port 2 and b2 Src Port 2
select the standard 2-port wave quantities a
1
, b
1
, a
2
, and b
2
, to be measured in forward or
reverse direction with port 1 or 2 providing the stimulus signal.
•
More Wave Quantities opens a dialog to define and select arbitrary wave quantities for different
detectors and source ports or more than 2 ports.
In contrast to S-parameters, wave quantities are not system error corrected. A power calibration can be
applied to wave quantities; see Data Flow in the System Overview chapter.
