Example
The current single measurement of sensor 2 which is assigned to trace 2 is used as
reference trace.
1. Select "Trace 2" with "Indication 2" = NRP-Zx.
2. Select "Save To Ref".
3. Select "Trace 1" and "Indication Ref.".
4. Select "Diagram".
The R&S SMA100B indicates two identical traces.
5. Select "Start single".
Triggers a new measurement cycle with sensor 2. You can compare the resulting
measurement trace with the former measurement, which is displayed as reference
trace.
Traces Settings
Indication - Power Analysis
Selects the source for the trace data.
The selection is indicated on the trace button in the measurement diagram.
"Off"
No source is selected, the trace is not indicated.
"2 - NRP-Zxx"
The current measurement results of the selected power sensor are
the source for the trace data. The index at the beginning of the sen-
sor name indicates the used connector, for example "2" indicates that
the sensor is connected via a USB interface. The data is either con-
tinuously updated (continuous measurement) or represents a single
measurement cycle (single measurement).
"Ref"
Selects the reference trace. The reference trace is a static trace that
was stored in a file and can be recalled.
It is possible to store one reference trace at a time.
"Hold"
Freezes the current trace data. The hold trace is a temporary trace
that is available until the power analysis is finished. Freezing the
trace of a sensor in one trace and displaying the measurement values
of the same sensor in another trace allows fast comparison between
measurements.
