Definition/Description Data Type Units
Specifies the rate at which Positive Hz/sec n/a

Parameter
n/a
NOTE – A positive value
results in a sweep
leg end frequency
that is higher than
the rest frequency,
a negative value
results in a sweep
leg end frequency
that is lower than
the rest frequency,
and a zero value
results in the sweep
leg ending at the
rest frequency.
endHoldDuration
The duration for which the
sweep leg end frequency is
to be held constant
(although possibly Dopplercompensated,
if applied)
before the leg ends.
