Press this softkey to change the hexadecimal value for the guard time
field. Guard time appears in the visual representation of the timeslot as
a 24.75-bit field. In the actual implementation, the guard time field in
timeslots 0 and 4 are 27 bits long and the remaining timeslots contain
24-bit fields. Use hexadecimal to enter the value; the signal generator
will convert it to binary.
The guard time field is always modulated (but not bursted), even when
the timeslot is off. If the guard time and
T2
symbols of the current
timeslot and the
T1
symbols of the next timeslot do not match, the burst
shape may not be smooth (even if the current timeslot is turned off).

Press this softkey to select Gated External Frame Trigger mode.
In Gated External Frame Trigger mode, the pattern waits at last bit
until the signal generator receives an inactive-to-active trigger
transition, at which time the pattern resets and runs to the end. At end
of pattern, if trigger level is still active, then the pattern repeats again.
Otherwise, pattern will stop and wait at the last bit until the trigger
signal transitions to active. After waiting at the last bit, upon receiving
an inactive-to-active trigger transition, the pattern resets and runs.
