Table B-1. Multimeter Command and Parameter Opcodes (continued)
(1)Specified as a 2’s complement binary number. For three byte parameters <upper byte> = value shifted 16 bits to the right (>>16), <middle byte> = value shifted 8 bits to the right (>>8), <lower byte> = value. For two byte parameters <upper byte> = value shifted 8 bits to the right (>>8), <lower byte> = value & 0xFF.
(2)Reading the Query Response register two times
(3)A parameter value of 0 sets infinite triggers per trigger arm.
(4)A parameter value of 0 sets infinite samples per trigger.
(5)Set when Sample Source is Timer.
(6)Used when Sample Source is Software. The first measurement of each burst occurs when the trigger signal is received (e.g. Trigger Immediate). Subsequent measurements in the burst occur when Software Sample is written to the Command register.
(7)Up to seven VXIbus TTLTrg trigger lines can be selected. 01 selects line 0, FF selects all lines.
