ANALOG OUTPUT COMMAND
This command enables or disables the ANALOG OUTPUT. See Section 3 for more information.
:SYSTem:OUT <n>
Enables or disables the ANALOG OUTPUT, where <n> is a single ASCII digit, as follows:
0 = Analog output turned off.
1 = Analog output turned on.
2 = Analog output turned on.
Note: "2" is an obsolete argument but still supported for backward compatibility with customer's existing software.
INTERMIXING “COMMON” AND SCPI COMMANDS
As mentioned earlier, a string sent to the instrument can contain more than one command as long as the commands are separated by
semicolons(;). “Common” and SCPI commands can be intermixed. For instance, the string:
*CLS;:UNIT:FLUX:DC:TESLA;:MEASure:FLUX?
is valid, first clearing the instrument’s event and error registers, then programming it to supply readings in tesla in the dc mode
and requesting the latest reading. The host system should be prepared to receive the reading immediately after transmitting this
command string to the meter.
USING QUERY COMMANDS
When any query command is issued, the meter will send its response back immediately. However, if a query command is part of a multiple
command string the meter will transmit the response after all commands within the string have been executed. For instance, here is such a
string:
:UNIT:FLUX:DC:GAUSS;:MEAS:FLUX?;:UNIT:FLUX:DC:TESLA;:MEAS:FLUX?
In this string, the meter is programmed for DC GAUSS mode and a measurement is requested. Then the meter is programmed
for DC TESLA mode and another measurement is requested. When the meter has finished executing the entire command
string, it will transmit a string similar to this: +1892G;+0.1892T.
