R&S FSL Setting Traces – TRACE Key
1300.2519.12 4.43 E-11
If the TV trigger is active, only the auto peak and the sample detector are available.
The result obtained from the selected detector within a measurement point is displayed as the power
value at this measurement point.
All detectors work in parallel in the background, which means that the measurement speed is
i
ndependent of the detector combination used for different traces.
Note: During a frequency sweep, R&S FSL increments the 1st local oscillator in steps that are smaller
than approximately 1/10 of the bandwidth. This makes sure that the oscillator step speed is
conforming to the hardware settling times and does not affect the precision of the measured
power.
The number of measured values taken during a sweep is independent of the number of
oscillator steps. It is always selected as a multiple or a fraction of 501 (= default number of trace
points displayed on the screen). Choosing less then 501 measured values (e.g. 125 or 251) will
lead to an interpolated measurement curve, choosing more than 501 points (e.g. 1001, 2001 ...)
will result in several measured values being overlaid at the same frequency position.
Softkeys of the trace menu
The following table shows all softkeys available in the trace menu. It is possible that your instrument
configuration does not provide all softkeys. If a softkey is only available with a special option, model or
(measurement) mode, this information is delivered in the corresponding softkey description.
