D-3
FIGURE D-4. SET COMMAND
Syntax: FNC DCS :CHnn SET VOLT <value> CURL <value>
FNC DCS :CHnn SET CURR <value> VLTL <value>
SRX
Set Range Maximum
SRN Set Range Minimum
Function: This operator is used in conjunction with FNC (in stimulus mode) to specify the output mode of the
power supply being programmed.
Description: The first operand is the noun modifier and the second operand specifies the value. The first operand
field of the command contains the four(4) letter mnemonic for the output mode of the power supply.
The choices are:
VOLT VOLTAGE MODE OPERATION
VLTL VOLTAGE LIMIT
CURR CURRENT MODE OPERATION
CURL CURRENT LIMIT
The second operand field of the command contains the value assigned to the chosen output mode.
This value may be specified as accurately as the resolution of the power supply allows. It can be
directly specified in ASCII integer, decimal, or in scientific notation.
There may be two (2) set commands, separated by a space (ASCII 32), for each power supply being
programmed. The following are the only allowable combinations:
VOLT with CURL
CURR with VLTL
The limit parameter (CURL or VLTL) may not be set without the main parameter. A polarity sign may
precede the VOLT or CURR value so that the power supply's polarity may be selected.
In the case of Kepco's MBT power supplies, the two related Op Codes, SRX and SRN are functionally
identical to the SET command, since there is only one range, 0 - maximum. The commands are
included only for compatibility.
Example: FNC DCS :CH12 SET VOLT 5 CURL 3Power supply at node address 12 commanded to 5V
(Voltage mode) with current limit of 3A.
FNC DCS :CH08 SET CURR 2 VLTL 17 Power supply at node address 8 commanded to 2A
(Current mode) with voltage limit of 17V
