Figure 3-e FREQUENCY SWEEP Tab
3.6.3 List Sweeps
List sweeps allow to set frequency, output power, dwell time and off time for each entry individually. To
start a list sweep, the following steps are required:
a) select sweep parameter
b) select indexing
c) upload list file from computer (CSV-file) or load sweep from instrument flash memory or edit
new list
d) select number of repetition
e) select ALC mode: on, hold or off. Generally ALC on is used. If very short dwell times (< 2 ms)
are needed, the ALC can be set to “hold”. This way the ALC loop is disabled during the
sweep. The ALC voltages are calibrated before the sweep to maintain high level accuracy
during the sweep
f) start sweep with on/off button
