1.4 REMOTE CONTROL
The BOP Power Supply can be remotely controlled directly using either a) analog signal applied
to the Analog I/O Port (see PAR. 3.6 for details) or b) digital commands via either the IEEE
488.2 (GPIB) bus (see PARs. 3.6.3) or RS232C interface (see PAR.3.6.4) using IEEE 488 and
SCPI commands (see and Appendix A and B, respectively). The unit can be controlled with a
VISA (Virtual Instrumentation Software Architecture) driver to facilitate remote programming of
the BOP Power Supply (see PAR. 3.6.5). The VISA driver is an interface written in standard C
language which adds the proper SCPI syntax to commands sent to the BOP.
The BITBUS is used to allow communication between identical BOP units that are connected in
series or parallel to expand the voltage or current range (see PAR. 2.8).
1.5 FEATURES
1.5.1 DIGITAL CALIBRATION
The BOP Power Supply is digitally calibrated except for the zero and full scale settings of the
output voltage analog readback signal which are accessed through a cutout at the rear of the
top cover and are done manually. Digital calibration is done via the GPIB or RS 232 interface
using digital entries and a calibrated DVM, a precision d-c reference voltage source and preci-
sion shunt resistor. Previous calibration values are saved and can be restored if desired. The
original factory calibration values can also be restored. (Refer to Section 4.)
1.5.2 VOLTAGE/CURRENT PROTECTION
Positive and negative voltage or current protection values can be individually programmed.
Refer to PAR. 3.3.4.
1.5.3 WAVEFORMS
The BOP models have the capability to make the output follow complex waveforms. These may
be generated either using an analog reference voltage having the desired shape (see PAR.
1.5.6), or digitally using SCPI commands (see PAR. 3.5.7).
Digitally, the waveforms can be generated by specifying individual points in the waveform or
through the use of standard waveform segments. The segments provided by the BOP are, lev-
els, positive and negative ramps, sine waves and triangle waves. While executing a waveform, it
is possible to cause other devices to be triggered by the BOP and for the BOP to wait for a trig-
ger from another device. Segments or a series of points at the beginning of the waveform can
be programmed to be executed only once, or to be repeated as specified by the count. This
feature provides unique versatility for generating preconditions, resulting in a waveform that can
meet a variety of user requirements.
