S terminals of the rear panel terminal block to monitor the output at the load, or between OUT
MON and COM MON to monitor the BOP output at the BOP (see Figure 2-1).
3.5.7.5 USING SEGMENTS TO BUILD A WAVEFORM
The following steps provide detailed instructions to show how a complex waveform, illustrated in
Figure 3-7, may be created by building segments. Refer to PAR. 3.7.3.3 additional information
of the use of LIST commands.
1. Send the following commands to create the trigger pulse and leading 0 volt level of the sam-
ple waveform (see Figure 3-7).
LIST:CLE Clears the list. Lists are not automatically deleted, but cannot
be saved for power-up.
LIST:VOLT:APPL LEV,.001,1.5 Sets the first segment at 1.5 volts for 1 millisecond.
LIST:VOLT:APPL LEV,.002,0 Sets the zero segment for 2 milliseconds.

SETTING CHOICES FUNCTION
Type Square
Pos Ramp
Neg Ram
Triangle
Sine
Level
Square - Square wave (constant 50% duty cycle), bipolar, starts with positive excursion
(see Note).
Pos Ramp - Increasing ramp, bipolar (see Note).
Neg Ramp - Decreasing ramp, bipolar (see Note).
Triangle - bipolar, starts with positive excursion, start/stop angle may be user controlled
(see Note).
Sine - - bipolar, starts with positive excursion, start/stop angle may be user controlled
(see Note).
Level - value determined by offset., duration determined by Period.
Frequency (Hz) or
Period (Sec) for Level
only xxxx.xxx (Hz) or
xx.xxxx (Seconds)
Square wave: 0.02 to 1000 Hz
Ramp: 0.02 to 532 Hz
Sine or Triangle:0.01 to 443 Hz
Level: Period (duration) in seconds. 0.0005 to 5.0000 seconds
Amplitude (P to P) xxx.xxx
(Volts or Amperes)
Peak to peak amplitude of segment. Volts or Amperes determined by mode selected
for waveform. Value within model rating acceptable (e.g., for BOP 100-10GL, maxi-
mum amplitude is 200V). Values that exceed the maximum or minimum software limits
(see PAR. 3.3.6) are neither accepted nor executed.
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 100-10GL,
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 100-10GL, 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. 3.3.5.1). Values that exceed the maximum or minimum
software limits (see PAR. 3.3.6) are neither accepted 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.
Initial - Segment is executed only on the first count and skipped for all subsequent
counts. Useful for preconditioning applications or establishing an initial delay.
All segments except the last may be set to Initial or Repeating. The last segment is
always Repeating
NOTE:
All waveforms except Level are centered on the offset. E.g. for a BOP 100-10GL, 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.
