Continuous Sweep
Sets the continuous sweep mode: the sweep takes place continuously according to the
trigger settings. This is the default setting.
The trace averaging is determined by the sweep count value (see the "Sweep Count"
softkey, "Sweep Count" on page 372).
Remote command:
INITiate<n>:CONTinuous on page 641
Single Sweep
Sets the single sweep mode: after triggering, starts the number of sweeps that are
defined by using the Sweep Count softkey. The measurement stops after the defined
number of sweeps has been performed.
Remote command:
INITiate<n>:CONTinuous on page 641
Continue Single Sweep
Repeats the number of sweeps set by using the Sweep Count softkey, without deleting
the trace of the last measurement.
This is particularly of interest when using the trace configurations "Average" or "Max
Hold" to take previously recorded measurements into account for averaging/maximum
search.
For details on trace configuration refer to Chapter 6.3.1, "Trace Configuration",
on page 387.
Remote command:
INITiate<n>:CONMeas on page 833
Sweeptime Manual
Opens an edit dialog box to enter the sweep time.
Sweep time
absolute max. sweep time value: 16000 s
absolute min. sweep time value: zero span: 1 μs
span > 0: depends on device model (refer to data sheet)
Allowed values depend on the ratio of span to RBW and RBW to VBW. For details
refer to the data sheet.
Numeric input is always rounded to the nearest possible sweep time. For rotary knob
or UPARROW/DNARROW key inputs, the sweep time is adjusted in steps either down-
wards or upwards.
The manual input mode of the sweep time is indicated by a green bullet next to the
"SWT" display in the channel bar. If the selected sweep time is too short for the
selected bandwidth and span, level measurement errors will occur due to a too short
settling time for the resolution or video filters. In this case, the R&S ESR displays the
error message "UNCAL" and marks the indicated sweep time with a red bullet.
When measuring Spurious Emissions, using this softkey automatically opens the
"Sweep List" dialog, see "Sweep List dialog box" on page 289.
