Solartron 1250 - Stopping and Re-Starting the Sweep; End of Sweep Conditions; Further Sweeps; Stopping and Re-Staring the Sweep

The Sweep Facility 1250 Frequency Response Analyzer
6-4 CHFR/1250/2
6.7 END OF SWEEP CONDITIONS
On the completion of a sweep, the Status of the Analyzers and Sweep controls will have
reverted to STOP, but the Generator will keep running at the last frequency
commanded.
6.8 FURTHER SWEEPS
To repeat the sweep described in Sections 4 and 5 above, the same procedure could be
repeated. A simpler way to repeat, or reverse, an already set-up sweep is to:
a. Press SWEEP START/CONTINUE, followed by the relevant soft key, as
explained in Section 4 step 5.
b. Press ANALYZER SINGLE or RECYCLE as before, but in this case, as the
Generator is already running, the Analyzer key now acts as the Sweep Start
Control.
To carry out further sweeps, using markedly different settings, it is advisable to repeat
Sections 4 and 5 sequence entirely.
6.9 STOPPING AND RE-STARTING THE SWEEP
6.9.1 INTRODUCTION
There are several ways of stopping a sweep, which can be grouped in two main
categories:
a. Those which produce the SWEEP STOP status. The sweep cannot now be
continued from the frequency at which it stopped but reverts to the relevant start
frequency and begins again from there. The START/CONTINUE key is used to
re-start the sweep.
b. Those which produce the SWEEP IDLE or HOLD status. The sweep can be
continued from the frequency at which it stopped. The sweep parameters can
also be changed before continuing.
6.9.2 COMMANDS WHICH PRODUCE "SWEEP STOP" STATUS
a. SWEEP STOP. The Analyzers will complete the reading at the current
Generator frequency, then continue to take readings at this frequency on
RECYCLE.
b. BREAK. The Generator continues running at the current frequency, but the
Analyzers and Sweep stop immediately. The Display will continue to show the
last reading taken before BREAK was pressed.
c. INIT. Whilst this command produces the SWEEP STOP condition, it also
returns all other settings to their default values, as described in Chapter 3.
d. RESET. As for INIT, but Learnt Programs and Files are not cleared.
e. Note that a normal continuous sweep, i.e. one where the Analyzers are set to
RECYCLE, stops automatically after taking a reading at the terminating
frequency. This also sets the SWEEP STOP status.
