Rate type
A rate type determines the time base of the waveform. Three types of rate
expressions (keywords) are supported.
• FREQUENCY (Hz, cps)
• TIME (msec, sec, minutes, and so on)
• RATE (units per time; for example, kips/sec)
A constant rate type of TIME= 2.5 sec assigns 2.5 seconds to each row of
segment data. When a constant is defined, the related column (Frequency/Rate/
Time) is not allowed. A variable rate type identifies a column of time values,
where each row can have a different time base.

Frequency, Time,
or Rate
*
* Rate is not supported by phase profiles.
Undetermined This entry is required. Only one of these three
can be specified. Rate must reflect the rate of
change of the Level dimension.
Count Greater than 0 This optional entry specifies the number of
repeats. The units can be segments or cycles,
and the value must be greater than 0. If this
option is omitted, the command will run once.
Shape Ramp, Sine, Square, TrueSine,
SquareTapered, RampTapered,
SineTapered, or
TrueSineTapered This entry is optional. When not assigned as a
constant, each segment can have a different
shape. The default is Sine.
Level1 Undetermined This entry is required.
Level2 Undetermined This entry is required for more than one
segment.
Phase Lag †
† Phase lag is not supported by block-arbitrary profiles.
0–360° This optional entry specifies the phase lag for
phase profiles. The default is 0.
