APPLy Output
The APPLy n subsystem commands provide the easiest method to output
voltages or currents.
/* Set channel 1 for 5.0 Volt output */
APPLy1:VOLTage 5.000
/* Channel is set to voltage output and 5.000 V applied */
/* Set channel 8 for 10 mA output */
APPLy8:CURRent 0.0100
/* Channel is set to current output and 10 mA applied */
The APPLy n subsystem outputs the voltage or current specified on the
channel specified immediately. The output relay for that channel is closed.
Other channel outputs and output states are not disturbed.
An APPLy n subsystem command performs several actions with a single
command. Each APPLy n command affects a single channel and:
– Sets the channel output mode (voltage or current).
– Sets the output value (volts or amps).
– Enables the outputs (closes the output relay).
The output channel remains enabled, and outputs the last programmed
voltage or current value, unless you take explicit action to turn off the
output. For example, if you send two
APPLy n commands to the same
channel, the first command sets an output value and closes the output relay.
The second command changes only the output value (since the relay is
already closed).
/* Set channel 1 for 5.0 Volt output */
APPLy1:VOLTage 5.000
/* Channel 1 is set to voltage output and 5.000 V applied */
/* Now set channel 1 for 6.0 Volt output */
APPLy1:VOLTage 6.000
/* Channel 1 is set to voltage output and 6.000 V applied */
The commands above will set a 5.000 Volt output on Channel 1, and then
set a 6.000 Volt output on channel 1. The output relay is not affected by the
second command.
