BIT 4882 COMPATIBILITY
The BIT 4886 card complies with the SCPI 1997 standard as a member of the power supply
instrument class. The Bit 4882 product complies with the 1990 version of the SCPI standard.
During the years of 1990 to 1997, the SCPI consortium refined the standard, providing direction
for the *RST command and indicating the differences between
*RST
and the single byte GPIB
command of
DCL
and
SDC
. The BIT 4886 card when shipped by KEPCO, is not compatible
with user software developed for the BIT 4882. The user can make it more compatible by using
the
SYST:SET
command to reconfigure the operation of
DCL
,
*RST
and the sending of data to
the host computer. Appendix B, Figure B-8, illustrates the use of the
SYST:SET
command to
change the BIT 4886 to operate like the BIT 4882, except for some minor differences that will
remain for some 4882 command sequences (see Table 1-5).
