be generated. A minimum of one and a maximum of 10 segments is allowed.
Sweep mode
The [Sweep Mode] key can be used to set the sweep to be externally or internally
triggered and to be in continuous or single shot mode.
This is identical to the trigger system used in the other sweep modes.
Starting to sweep
To start a sweep press the [Start Sweep] key on the Sweep Sequence selection menu
(Fig. B-12). The signal generator will start sweeping and display the current frequency,
RF level, step time and the segment number it is currently in. If the sweep has been set to
go through a number of segments at different levels the display is updated to show the
change of setting.
Before the start of a sweep the RF or LF settings of the generator can be inspected by pressing the
[RF Info
.] or
[LF Info
.] keys.
When a sweep is in progress the sweep can be stopped at any point using the
[Stop Sweep
] key
and a display similar to Fig. B-14 will be shown. The carrier frequency and RF level can be
varied by using the rotary control.
