Querying Parameter Settings
You can query the current value of most parameters by adding a
question mark ( ? ) to the command. For example, the following command sets
the trigger count to 10 readings:
TRIG:COUN 10
You can then query the count value by sending:
TRIG:COUN?
You can also query the minimum or maximum count allowed as follows:
TRIG:COUN? MIN
TRIG:COUN? MAX
