output
Ramp up/down period Settable 100 µs to 30 seconds
Optional end delay 0 to 60 seconds ± 31 µs
Trigger out delay 0 to 60 seconds from start of dip/swell event
Trigger out TTL falling edge co-incident with end of trigger out delay,
remaining low for 10 µs to 31 µs

4-47. Setting Up Dips/Swells
The top level Dip/Swell softkeys are shown in Figure 4-25. The Waveshape softkey
opens the lower level softkeys for the various parameters that control the shape of the
Dip/Swell. Under Trigger various Dip/Swell trigger options can be set. Dip/Swell
Repetitions determines how many Dip/Swell events will occur when a trigger occurs in
External Trigger (One Shot) mode. Copy and Paste allow transfer of the current
settings to another 6100B phase. Use the Enable/Disable Waveshape softkey to turn
Dip/Swell on or off.
