Stop Hold
Stop Hold is the duration that the output signal still outputs with the “Stop
Frequency” after the generator has swept from the “Start Frequency” to the “Stop
Frequency”.
When Sweep is enabled, press Stop Hold and use the numeric keyboard or
direction keys and knob to change the stop hold. The default value is 0s and the
available range is from 0s to 500s.
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 source. When Sweep is enabled, press Trigger  Source to select “Int”,
“Ext” or “Manual”. The default is “Int”.
1. Internal Trigger
The generator outputs continuous sweep waveform when internal trigger is
selected. The trigger period is determined by the specified sweep time, return
time, start hold and stop hold times.
Press TrigOut to select “Leading” or “Trailing” and the [CH1/Sync/Ext
Mod/Trig/FSK] connector at the rear panel will output trigger signal with
specified edge.
2. External Trigger
The generator accepts the trigger signal inputted from the [CH1/Sync/Ext
Mod/Trig/FSK] connector at the rear panel when external trigger is selected.
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”.
