End Hold
End Hold is the duration that the output signal outputs with the “End Frequency”
after the generator has swept from the “Start Frequency” to the “End Frequency”.
When Sweep is enabled, use to open the 2/2 menu page, then press End
Hold and use the numeric keyboard or knob to change the End Hold. The default
value is 0s and the available range is from 0s to 300s.
The generator will renewedly sweep and output from the specified “start
frequency” once the End Hold is changed.
Sweep Trigger Source
The Sweep trigger source could be internal, external or manual. The generator will
generate a sweep output when a trigger signal is received and then wait for the
next trigger.
When Sweep is enabled, use to open the 2/2 menu page and press Source
to select “Int”, “Ext” or “Manual”. The default is “Int”.
1. Internal Trigger
The generator outputs continuous sweep waveform. The trigger period is
determined by the specified sweep time, return time, start hold and end hold
times.
2. External Trigger
The generator accepts the trigger signal input from the [Mod/FSK/Trig]
connector at the rear panel. A sweep will be generated once the connector
gets a TTL pulse with specified polarity. To set the TTL pulse polarity, press
SlopeIn to select “Leading” or “Trailing”. The default is “Leading”.
Note that in “Int” and “Manual” trigger modes, the corresponding menu is
TrigOut. The [Mod/FSK/Trig] connector at the rear panel is used as the
output terminal of trigger signal.
