CURR 2.0
The two commands shown in this example has the same function as the first
command shown in the above example, which shows when some individual parameter
is changed, there is no need to enter the whole setting parameters as the above
example, just enter some specified parameter.
Reading a Query Response
Only the query commands (commands that end with “?”) will instruct the power
supply to send a response message, which gives the either returned values or internal
instrument settings. Take below commands as examples to illustrate:
SYST:ERR? Query and read the error message, and return a relevant error
message
CAL:SEC:STAT? Query the calibration security, and return the relevant value
SYST:VERS? Query the system version, and return the version number
accordingly
Selecting a Trigger Source
The power supply will accept a “bus” (software) trigger or an immediate internal
trigger as a trigger source. By default, the “bus” trigger source is selected. If you want
the power supply to use an immediate internal trigger, you must select “IMMediate”.
For example:
TRIG:SOUR IMM Select an immediate internal trigger as a trigger source
INIT Initiate the trigger system
Using the APPLY Command
APPLy
{<voltage>|DEF|MIN|MAX}[,{<current>|DEF|MIN|MAX}]]
This command is to specify the power supply’s output, which can be divided into
three parts:
The first part is the keyword “APLLy”.
The second part is to set the voltage value
{<voltage>|DEF|MIN|MAX},
by which
you can set the output voltage value of the specified supply. For the setting range,
please consult the relevant voltage parameters listed in the table of “Programming
Ranges and Output Identifiers” section.
The third part is to set the current value
{<current>|DEF|MIN|MAX},
by which you
