Status register format
SREGister <name>
:FORMat:SREGister <name> Set data format for reading status registers
Parameters <name> = ASCii Decimal format
Hexadecimal Hexadecimal format
OCTal Octal format
BINary Binary format
Query :SREGister? Query format for reading status registers
Description Query commands are used to read the contents of the status event registers. This
command is used to set the response message format for those query
commands.
When a status register is queried, the response message is a value that indicates
which bits in the register are set. For example, if bits B5, B4, B2, B1, and B0 of a
register are set (110111), the following values will be returned for the selected
data format:
ASCii 55 (decimal value)
Hexadecimal #H37 (hexadecimal value)
OCTal #Q67 (octal value)
BINary #B110111 (binary value)
See Section 13 and “Status Structure” in this section for more information.
OUTPut subsystem
This subsystem is used to control the voltage source outputs and the output enable line. These
commands are summarized in Table 16-4.
Turn source on or off
[:STATe] <b>
:OUTPut[1][:STATe] <b> Turn source 1 on or off
:OUTPut2[:STATe] <b> Turn source 2 on or off
Parameters <b> = 0 or OFF Turn source off (standby)
1 or ON Turn source on (operate)
Query :OUTPut[1]? Query state of source 1
:OUTPut2? Query state of source 2
Description These commands are used to turn the channel 1 and channel 1 source outputs on
or off.
Turning a source off places the Model 6482 in the idle state. The only exception to
this is when source auto clear is enabled. In this mode, the source turns on during
each source phase of the SDM cycle and then turns off after each measurement.
See :SOURce[1]:CLEar:AUTO and :SOURce2:CLEar:AUTO in “SOURce sub-
system,” page Section 16-40.
NOTE The :SOURce[1]:CLEar or :SOURce2:CLEar command will also turn the respective
source off.
