Selects single or continuous bargraph measurements.
Continuous bargraph measurements continuously evaluate the signal level at the
receiver frequency.
A single bargraph measurement evaluates the signal level at the receiver frequency
once and then stops.

5.1.7.4 Scan Control
At the start of a scan, the R&S ESR opens a softkey menu to control the measure-
ment.
Interrupting a scan
The R&S ESR allows to interrupt a scan any time. If you interrupt it, the scan stops
immediately. The scan stops at the frequency at which it was interrupted until it is con-
tinued. While the scan is stopped, the receiver settings can be changed, e.g. for a
detailed analysis of the recorded trace. You have two options to continue the scan or
you can abort it.
●
Continue at a set receiver frequency - "Continue at Rec Frequency".
The receiver frequency can be set to a frequency that was already measured. As
soon as the "Continue at Rec Frequency" softkey is pressed, the scan restarts at
this frequency. This function can be used repeat part of the measurement.
●
Continue at the hold frequency - "Continue at Hold"
Resumes the scan at the frequency it has been interrupted.
●
Continue at a spectrogram frame - "Continue at Frame"
Resumes the scan at a spectrogram frame that was already recorded.
●
Stop the scan - "Abort Scan"
Aborts the scan.
