RUN SCAN
4.5.5.6 Running a Scan
The RUN SCAN softkey starts the frequency scan with the selected settings. The
HOLD SCAN submenu is displayed instead of the menu shown before the scan is
started.
At the beginning of the scan, R&S ESU sets up the diagram as specified in the scan
table and starts the scan in the selected mode (
SINGLE or CONTINUOUS ). With
SINGLE selected, R&S ESU performs a single scan and stops at the end frequency.
With CONTINUOUS selected, the scan is performed continuously until it is deliber-
ately stopped.
The measurement can be interrupted with HOLD SCAN or stopped with STOP
SCAN . The two softkeys are displayed instead of the menu shown before the scan
is started.
If a transducer set is defined with points of changeover, the scan automatically stops
at the frequencies of the new subrange of the transducer set and the user may
exchange the transducer.
The following message informs the user that the limit has been reached:
TDS Range # reached, CONTINUE / BREAK
He can continue the scan at the point of change over by confirming the message
(
CONTINUE ) or he can switch off the transducer ( BREAK ).
Remote command:
INIT2
HOLD SCAN The HOLD SCAN softkey interrupts the scan.
The scan stops at the frequency at which it was interrupted until it is continued with
the
CONT AT REC FREQ or CONTINUE AT HOLD softkeys.
While the scan is stopped, the receiver settings can be changed, e.g. for a detailed
analysis of the recorded trace.
Remote command:
:HOLD
CONT AT REC
FREQ
With the CONT AT REC FREQ softkey the scan is continued at the current receiver
frequency when the receiver frequency is lower than the frequency at which the
scan was interrupted. Otherwise the scan continues at the frequency at which it was
interrupted.
The scan is always continued with the settings in the scan table.
