Sweep & Hop Modes
This screen (
) allows you to set
power
or
frequency
sweeps of the output signal,
or to specify an arbitrary list of power & frequency settings (Hop Mode) for a single generator. For
synchronized sweeps of multiple generators see section
3.8 Multi Gen. Control.
3.6.1
Common functions:
A number of functions at the top and bottom of the screen remain the same, regardless of the specific
sweep mode selected, the common functions are:
Freq Sweep
– Sets the screen to Frequency Sweep mode (see section
).
Power Sweep
– Sets the screen to Power Sweep mode (see section
).
Hop Mode
– Sets the screen to Hop (arbitrary list) mode (see section
).
Generator Model
–
Displays the model
P/N
of the generator in use.
Serial Number
– Displays the
serial number
of the generator in use.
Icons
– The icons circled in
allow (from left to right): Clearing all settings of the sweep/list;
recalling a previously stored sweep or list; saving current settings. (see section
Dwell Time
– The duration of each point in the sweep. Check individual model datasheets for minimum
dwell time.
Trigger In
– Controls what trigger input is required. Options are:
Ignore: No trigger input, the generator will sweep continuously.
Before Each Point: A trigger input is required before switching to the next point in the sweep.
Before Cycle: A trigger input is required before commencing each sweep/restarting the list.
Trigger Out
– Controls when the generator will produce a trigger output. Options are:
Ignore: No trigger produced.
At Each Point: A trigger produced at the start of each point in the sweep.
At end of Cycle: No trigger produced for individual points in the sweep. However, a trigger will be
produced at the end of every cycle of the sweep pattern.
Direction
– Controls the sweep direction. Options are:
Forward(From start of list): Sweep goes from Start point to Stop point, then repeats from Start point.
Reverse(From end of list): Sweep goes from Stop point to Start point, then repeats from Stop point.
Bi-Directional: Sweep goes from Start point to Stop point, then Sweeps back to Start point before
repeating.
Off
– Stops the current sweep.
Run Sweep
– Starts the sweep with the specified parameters. Once started, additional changes in
parameters will have no effect until after the sweep is stopped.
PC Timing control
– Closes the sweep window and transfers to antiquated Sweep & Hop control screen
with the timing of each point controlled by the PC instead of the generator. This
method introduces additional communication delays between the PC and generator.
Notes:
1.
SSG models use a trigger of ‘1’.
2.
Any command sent to the generator during the Sweep/Hop will result in stopping the sequence.
