To delete a segment, highlight the segment at the Waveform Settings screen (Figure 3-10), the
press
# , to permanently erase the segment. This change is saved immediately and can not be
undone.
To add a segment, at the Waveform Settings screen (Figure 3-10) highlight the segment follow-
ing the one to be added (e.g., if there are three existing segments (1, 2, 3), to add a segment
between 2 and 3, highlight 3. To add a segment following 3, highlight
End of Segments . After
highlighting the segment, press
@
to insert a new segment. The parameters applicable to the
waveform type selected (see Table 3-11 for details) can then be modified as desired.
3.3.9.8 CREATING A NEW WAVEFORM
1. After observing the precautions of PAR. 3.3.9.1, press @ from the power-up screen to enter
the Saved Waveforms screen (Figure 3-9), highlight one of the waveforms designated
Empty , then press @ . The Waveform Settings screen (Figure 3-10) opens.
Offset xxx.xxx
(Volts or Amperes)
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 offset 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 software 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 acepted nor executed.
Start Angle
(Sine or Triangle only) xxx x
(degrees)
The point at which the sine or triangle waveform segment starts. Values from 0.0° to
360.0° are acceptable. Default is 0.0°.
Stop Angle
(Sine or Triangle only) xxx x
(degrees)
The point at which the sine or triangle waveform segment stops. Values from 0.0° to
360.0° acceptable. Default is 0.0° (functions the same as 360°)..
Initial/ Repeat Repeating
Initial
Repeating - Segment is executed for each cycle specified by the Count (see Note 2).
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
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.
