• I
f the sweep range is defined by means of the Start an
d Stop variables, both the Stop value and
the Number of Points can vary as the Stimulus Step Size is changed. The Stop value is changed
as little as possible so that the condition Stimulus Step Size = (Stop – Start) / (Number of Points –
1) can be fulfilled. Changing the Start and Stop values modifies the Stimulus Step Size.
• If the sweep range is defined by means of the Center and Span variables, both the Span value
and the Number of Points can vary as the Stimulus Step Size is changed. The Span is reduced as
little as possible so that the condition Stimulus Step Size = (Stop – Start) / (Number of Points – 1)
can be fulfilled. Changing the Span modifies the Stimulus Step Size.
This setting is valid for linear frequency sweeps only. It does not apply to logarithmic and segmented
sweeps. Increasing the Frequency Step Size generally increases the measurement time.
Remote control:
Meas Delay
Sets a delay time before the start of each partial measurement. This setting is not available on R&S
ZVL13 network analyzers.
A measurement delay time increases the accuracy, in particular in measurements on DUTs with long
settling times (e.g. quartzes, SAW filters).
Remote control:
Restart
Stops the current measurement and restarts a measurement sequence. In Single sweep mode a new
single sweep sequence is started.
Remote control:
INITiate<Ch>[:IMMediate]
Single (All Chans)
Toggles between single sweep and continuous sweep mode.
• In continuous mode (Single (All Chans) not selected), the analyzer measures continuously,
repeating the current sweep.
• In single sweep mode, the measurement is stopped after the number of sweeps selected in the
Define Restart dialog.
Press Single to activate the single sweep mode and start a single sweep sequence. To start further
sweep sequences press Restart.
Remote control:
INITiate<Ch>:CONTinuous ON | OFF
