A.1 INTRODUCTION
This appendix defines the CIIL commands used with the MAT Power Supply. Table C-1 provides
a quick reference of all CIIL commands used in the MAT Power Supply.

Syntax: Stimulus mode: FNC DCS :CHnn
Sensor mode:
FNC DCS :CHnn
Function: This operator is used with either the SET command to program a power supply's output (stimulus
mode), or with the VOLT and CURR commands to read its output settings (sensor mode).
Description: The first operand contains the three (3) letter mnemonic pertaining to the device on the control bus, in
this case DCS (Direct Current Source). If a reading is being set up, the modifier VOLT or CURR fol-
lows. The next operand is used to select the specific channel of the device being programmed or read
from. The MAT can control up to 27 power supplies/power modules with control bus addresses in the
range of 1 to 31.
Example: FNC DCS :CH12 SET VOLT 15 Power supply at node address 12 commanded to 15V
FNC DCS :CH12 SET CURR 3 Power supply at node address 12 commanded to 3A
FNC DCS VOLT :CH03 Power supply at node address 3 returns value which represents
actual output voltage
FNC DCS CURR :CH21 Power supply at node address 21 returns value which represents
actual output current
NOTE: Actual output voltage and current depends on whether output is enabled or disabled
and load conditions
