B.2

NUMERICAL VALUES

The SCPI data parser on the BOP supports a maximum of 8 digits after the decimal point and a maximum inte-
ger of 4 x 10

8

. Any values greater than these are not processed by the device and no error is generated. The

largest string that can be received or transmitted by the BOP is 253 characters. All numerical data is returned
in scientific notation, digits with decimal point and Exponent, e.g., 2.71E1 for 27.1.

The BOP’s SCPI data parser for all decimal values supports a maximum of eight digits after the decimal point
and a maximum integer of 4 x 10

8

. Any values greater than these are not processed by the device and no error

is generated.

The unit also supports keywords of MAXimum and MINImum to set the numeric entry to the most positive and
negative allowable values, respectively. For example, If the user has established the volt:limit to be 6, sending
the command VOLT MAX causes the output to be set to 6 volts. This syntax can be very useful in the setting of
a limit, e.g., VOLT:PROT:LIM MAX sets the positive voltage protection limit to the maximum voltage (E

O

max +

1%) and the negative voltage protection limit to (-1.01 x E

O

max).

B.3

ABORt COMMAND

ABOR

Syntax:

Short Form: ABOR

Long Form: ABORt

Description: Cancels previously stored trigger levels, resets WTG. The ABORt command cancels any pending

trigger levels previously stored by the CURR:TRIG or VOLT:TRIG commands. The pending level is set
equal to the corresponding immediate value. ABORt also resets the WTG (Wait TriGger) bit in the
Operation Condition status register. If INIT:CONT ON has been programmed, the trigger system re-
arms itself immediately after ABORt, thereby setting WTG. WTG is bit 5 in the STATUS OPERATION
CONDITION register. The ABORt is executed each time power is turned on. Related Commands:
INIT, *RST, *TRG. (See example, Figure B-1.)

CAL

COMMANDS AND QUERIES

CAL

CAL commands and queries are used to perform calibration of the unit via the control interface. These
commands must be issued in a specific sequence in order to properly calibrate the unit. To use these
commands, refer to Kepco’s website (www.kepcopower.com/drivers) and download the LabWindows/
CVI Version 5 driver for BOP or refer to PAR. 4.3.1. This file provides remote calibration capability and
uses the following supported commands and queries:

CAL:CEXT command
CAL:CGA command
CAL:CLIM command
CAL:CPR command
CAL:CURR[:DATA] command
CAL:DATA value command
CAL:DPOT command
CAL:SAVE command
CAL:STAT command and query
CAL:VEXT command
CAL:VGA command
CAL:VLIM command
CAL:VOLT[:DATA] command
CAL:VPR command
CAL:ZERO command
