cal.
Manual operation: See "Preset User Cal" on page 524
SYSTem:SETTings:UPDate <Activate>
Initiates an immediate update of the channel or trace settings.
The command has an effect if the analyzer operates in single sweep mode
(
INITiate<Ch>:CONTinuous OFF
). In this scenario, a change of the channel or
trace settings is usually not taken into account immediately. The analyzer waits until
the end of the current sweep sequence and changes all settings made during the last
sweep period when the next single sweep sequence is initiated. Several settings can
be made en bloc, which generally saves time.
