After enabling sweeps, press 〖Hold Time〗 softkey. Then use the knob or numeric keypad to enter
the desired sweep time. The hold time specifies the number of seconds to remain at the stop
frequency. This allows the stop frequency to be sustained for a set time.
5.10.7 Return Time
After enabling sweeps, press 〖Return Time〗 softkey. Then use the knob or numeric keypad to enter
the desired sweep time. The return time specifies the number of seconds to return from the stop
frequency to the start frequency. No matter sweep mode is Linear or log, linear sweep will be the only
mode on return sweep.
5.10.8 Sweep Trigger Source
Press 〖Trig Imm/Ext〗softkey. When the Immediate (Internal) source is selected, the waveform
generator outputs a continuous sweep at a rate determined by the total of the hold time, sweep time
and return time.
When the External source is selected, the waveform generator outputs one sweep each time you
press 〖Manual Trig〗 softkey. Or the waveform generator initiates one sweep each time
input TTL level trigger signal from Trig In connector on the rear panel. The trigger period must be
greater than the total of the hold time, sweep time and return time.
