Sweep Trigger Source
In the sweep mode, the function generator outputs a single sweep when a
trigger signal is received. After one sweep from the start frequency to the
stop frequency, the function generator waits for the next trigger while
outputting the start frequency.
• Sweep trigger source:
Internal
, External, or Manual. The default
is Internal.
• When the Internal (immediate) source is selected, the function
generator outputs a continuous sweep at a rate determined by the
sweep time specified.
• When an External source is selected, the function generator will
accept a hardware trigger applied to the rear panel Trig In connector.
The function generator initiates one sweep each time Trig In receives
a TTL pulse with the specified polarity.
• The trigger period must be greater than or equal to the specified
sweep time
plus
1 ms.
• When the Manual source is selected, the function generator outputs
one sweep each time the front-panel key is pressed.
• Front-Panel Operation: Press the
Trigger Setup
softkey and then
select the desired source by pressing the
Source
softkey.
To specify whether the function generator triggers on the rising or
falling edge of the Trig In connector, press the
Trigger Setup
softkey.
Then select the desired edge by pressing the
Slope
softkey.
• Remote Interface Operation:
TRIGger:SOURce {IMMediate|EXTernal|BUS}
Use the following command to specify whether the function generator
triggers on the rising or falling edge of the signal on the Trig In
connector.
TRIGger:SLOPe (POSitive|NEGative}
