Output enable control
ENABle[:STATe] <b>
:OUTPut[1]:ENABle[:STATe] <b>Control output enable for both sources
Parameters <b> = 0 or OFF Disable output enable
1 or ON Enable output enable
Query :ENABle[:STATe]? Query state of output enable
Description This command is used to enable or disable the output enable line. When enabled,
the sources cannot be turned on unless the output enable line (pin 8 of the rear
panel OUTPUT ENABLE connector) is pulled to a logic low state. When the output
enable line goes to a logic high state, both sources turn off. See
Section 11 ,
“Output enable” and “Output enable,” for details using output enable with a test
fixture.
When disabled, the logic level on the output enable line has no effect on the out-
put state of the source.
TRIPped?
:OUTPut[1]:ENABle:TRIPped?
Description This query command is used to determine if output enable has been tripped. The
tripped condition (“1”) means that the sources can be turned on (output enable
line at logic low level).
A “0” will be returned if the sources cannot be turned on (output enable line at
logic high level).
SENSe subsystem
The SENSe subsystem is used to configure and control the measurement functions of the
Model 6482. SENSe[1] controls channel 1 measurement functions, and :SENSe2 controls channel
2 functions. Some of the commands are global, where a single command affects both channels.
Other commands are unique to a specific channel. For example, you can program a unique range
setting for each channel. A channel does not have to be selected before you can program its
various configurations. Whenever a programmed channel is selected, it assumes the programmed
states.
The commands for this subsystem are summarized in Table 16-5 .
