Note: Pressing the [RUN CONT] key again interrupts the scan (see Chapter 9.3.3.2,
"Interrupting a Scan", on page 115) and does not stop it.
Continuous measurements are the default measurement mode.
Remote command:
Selection: INITiate<n>:CONTinuous on page 441
Initialization: INITiate<mt>[:IMMediate] on page 442
Performing single measurements
When you run a single measurement, the measurement is performed once and then
stopped. The duration of the measurement depends on the measurement time.
Note that a single measurement does not necessarily consist of a single measurement.
A single measurement can consist of several measurements, whose number you can
define with the Scan Count. In that case, the measurement stops when all measure-
ments defined by the scan count or bargraph count are done.
The R&S ESW allows you to select the measurement mode for the bargraph and the
scan separately. When you select a single bargraph measurement, IF analysis also
stops when the bargraph measurement stops. Note, however, that the time defined for
a single bargraph measurement can result in more than one update of the IF analysis
trace (including the IF spectrogram). When you select a single scan, the spectrogram
update also stops when the scan stops, but it can consist of several new lines in the
spectrogram, depending on the configuration.
▶ To start a single scan, press either the [RUN SINGLE] key on the front panel or the
"Single Scan" softkey in the "Sweep" menu.
▶ To start a single bargraph measurement, press the "Single Bargraph" softkey in the
"Sweep" menu.
Note: Pressing the [RUN SINGLE] key again interrupts the scan (see Chapter 9.3.3.2,
"Interrupting a Scan", on page 115) and does not stop it.
Note on performing continuous sequenced measurements:
When you are using the sequencer, you can select the measurement mode for each
measurement channel that is part of the sequence.
Thus, the "Single Scan" and "Single Bargraph" softkeys only control the measurement
mode for the currently selected measurement channel (for a channel defined
sequence). In addition, the [RUN SINGLE] key in that case controls the sequencer, not
a particular channel.
Remote command:
Selection: INITiate<n>:CONTinuous on page 441
Single scan or bargraph: INITiate<mt>[:IMMediate] on page 442
Single final measurement: INITiate<mt>:FMEasurement on page 442
Single test sequence: INITiate<mt>:EMITest on page 442
Performing sequenced measurements
When you run a sequenced measurement, you can combine measurements of several
applications into a sequence of measurements. This sequence of measurements is
either performed once (single sequence), indefinitely (continuous sequence) or a mix-
ture of both (channel defined sequence).
