NOTES
1. All waveforms except Level are centered on the offset. E.g. for a BOP 100-10MG, a positive ramp of 100V p-p amplitude, 10V
offset, will start at -40V and increase to +60V over the time period (T) determined by the frequency (F): T = 1/F.
2. When starting a new waveform, the first segment is always a repeating segment. One or more initial segments can be inserted
before the first repeating segment. Segments inserted before an initial segment are automatically set to initial; segments
inserted after a repeating segment are automatically set to repeating. It is recommended that the repeating segments be created
first. E.g. For a waveform with five segments, 1 and 2 designated Initial and 3, 4, and 5 designated Repeating, If the count was
set to 10, the first waveform would be comprised of segments 1 through 5, but the next nine waveforms would only have seg-
ments 3, 4, and 5. This feature can be useful for establishing an initial delay or preconditioning the load prior to running the
repeating waveform.
3. If the internal memory space used to process a waveform segment is exceeded, *** is displayed to the left of the segment(s) in
error. This can be corrected by 1) increasing the frequency (the lower the frequency, the more memory is used), 2) reducing the
number of segments.

CHOICES
Square Square - Square wave, bipolar, starts with positive excursion (see Note 1).
Pos Ramp Pos Ramp - Increasing ramp, bipolar (see Note 1).
Neg Ram Neg Ramp - Decreasing ramp, bipolar (see Note 1).
Triangle Triangle - bipolar, starts with positive excursion, start/stop angle may be user controlled
Sine (see Note 1).
Level Sine - - bipolar, starts with positive excursion, start/stop angle may be user controlled
(see Note 1).
Level - value determined by offset., duration determined by Period.
Square wave: 0.02 to 1000 Hz
Ramp: 0.02 to 532 Hz
Sine or Triangle:0.01 to 443 Hz
Level: Period in seconds. 0.005 to 5.0000 seconds
xxx.xxx Peak to peak amplitude of segment. Volts or Amperes determined by mode selected
for waveform. Value within model rating acceptable (e.g., for BOP 100-10MG, maxi-
mum amplitude is 200V). Values that exceed the maximum or minimum software limits
(see PAR. 3.3.4.2) are neither accepted nor executed.
xxx.xxx DC level on which the waveform (centered) will ride or Amplitude for Level segments.
Volts or Amperes determined by mode selected for waveform. E.g. for BOP 100-10MG,
to specify a positive ramp that goes from +30V to +80V, set amplitude to +50V and off-
set to +55V. Since p-p amplitude of segment is centered on offset, it is possible for the
waveform to exceed the model ratings (e.g., for the BHK 100-10MG, if the amplitude is
set to 150V and the offset is -50V, the negative portion of the segment will exceed the -
100V maximum of the model). In this case the output is clamped to the max/min soft-
ware limit in effect (see PAR. 3.3.4.1). Values that exceed the maximum or minimum
software limits (see PAR. 3.3.4.2) are neither accepted nor executed.
xxx x The point at which the sine or triangle waveform segment starts. Values from 0.0° to
(degrees) 360.0° are acceptable. Default is 0.0°.
xxx x The point at which the sine or triangle waveform segment stops. Values from 0.0° to
(degrees) 360.0° acceptable. Default is 0.0° (functions the same as 360°).
Repeating Repeating - Segment is executed for each cycle specified by the Count (see Note 2).
Initial Initial - Segment is executed only on the first count and skipped for all subsequent
counts. Useful for preconditioning applications (see Note 2).
All segments except the last may be set to Initial or Repeating. The last segment is
always Repeating
