SOURce Output
Setting an output on a channel is a three step process:
– Set the channel mode (voltage or current)
– Set the channel output value (volts or amps)
– Enable the output (close the channel output relay)
As described previously, a single APPLy n command performs all three of
these actions. In some cases you may need more control of each step in the
output process. The following commands perform the same action as a
single
APPLy n command.
/* Set channel 1 voltage mode */
SOURce1:FUNCtion:MODE VOLTage
/* Channel 1 is set to voltage output */
/* Set channel 1 voltage output */
SOURce1:VOLTage 5.000
/* Channel 1 is set to output 5.000 Volts */
/* Turn on the output */
OUTPut1 ON
/* Channel 1 output is enabled */
The SOURce n subsystem contains two types of commands to set current or
voltage output. The type used in the above examples has the form:
SOURce n :CURRent[:LEVel][:IMMediate][:AMPLitude] < value >
SOURce n :VOLTage[:LEVel][:IMMediate][:AMPLitude] < value >
The implied commands (enclosed in brackets [ ]) are not shown in the
examples. The commands shown above immediately program the output
values. The
SOURce n subsystem also contains commands of the form:
SOURce n :CURRent[:LEVel]:TRIGgered[:AMPLitude] < value >
SOURce n :VOLTage[:LEVel]:TRIGgered[:AMPLitude] < value >
These commands are used with the trigger system to control when the
outputs are applied. The trigger system is described on page 54.
