Reset: 0 causes no change, 1 causes board reset and
triggers the relay timer. Clears itself afterward.
Reset causes Inst16 to be connected to the Inst MUX and Isense relay is
disconnected
Since the card level reset bit is "OR'd" with the back plane reset, the
state of the Reset bit during read also indicates the state of the back
plane reset line.
•
GndRly: 0 opens relay from Inst2 (DMM Lo) to System
Gnd (default), 1 closes relay from Inst2 (DMM Lo) to
System Gnd
•
DAC1Rly: 0 opens relay from Inst1 (DMM Hi) to DAC1
(default), 1 closes relay from Inst1 (DMM Hi) to DAC1
•
DAC2Rly: 0 opens relay from Inst1 (DMM Hi) to DAC2
(default), 1 closes relay from Inst1 (DMM Hi) to DAC2
The above values are valid for the Agilent E8792A only.
When measuring DAC1 or DAC2, system ground must be
connected to low side of DMM.
•
ISensRly: 0 opens relay from Inst16 (Spare16) to ISense
(default), 1 closes relay from Inst16 (Spare16) to Isense.
The above value is currently not implemented.
Writing a 1 to IsensRly disconnects INST16 from the instrument matrix.
Writing a 0 to IsenseRly connects INST16 to the instrument matrix.
•
OAR: 0 causes no change, 1 causes all relays to open.
