:READ[1|2]?
The READ? command changes the state of the trigger system from the idle state to the wait-for-trigger state.
When the specified trigger condition requirements are met after the instrument receives the READ? command,
the measurement is initiated. The result is sent to the output buffer immediately. You must enter the reading data
into your bus controller or the instrument will stop making measurements when the output buffer fills. Readings
are not stored in the instrument’s internal memory when using the READ? command.
To take many samples quickly, use INIT;:FETC?.
Variations
READ1?
Initiates the trigger model and transfers the readings from the primary measurement function
to the output buffer.
READ2?
Initiates the trigger model and transfers the readings from the secondary measurement
function to the output buffer.
Example
:READ2?
