F3: DELAY - This parameter is used in two instances. The first is to set the delay of the
pulse in the single pulse mode. The delay governs the time from the SYNC
signal to the start of the pulse. The second instance is the double pulse mode.
Here the delay governs the time from the SYNC pulse to the second pulse. The
minimum and maximum values of the delay are dependent on the values of the
period, width and leading and trailing edge times. The delay range is 0 to
9.80000s.

F5: SINGLE/DOUBLE - The unit can be set to generate either a SINGLE pulse or a DOUBLE pulse. In
the double pulse mode, the first pulse is generated without delay from the start
and the second pulse in generated after a delay, from the start of the period, as
determined by the DELAY parameter. Thus, in order to generate a double pulse,
the delay must first be set, and then the double pulse may be set on. The double
pulse mode state is toggled using either the F5 key. The minimum and
maximum values of the delay are determined by the values of the period, width,
delay and transition parameters.

3.6.2 OUTPUT Menu
The Output menu enables the pulse high and low levels to be set. The levels are limited by four
factors:
- The absolute limits are ±10V.
- The high level must be greater than the low level.
- The pulse amplitude must be between 0.1V and 10V p-p, into 50 ohms.
- The levels cannot exceed the limits as set in the OUTPUT LIMITS menu.
