Agilent Technologies 34420A User Manual

Using the READ? Command
The READ? command changes the state of the trigger system from the
“idle” state to the “wait-for-trigger” state. Measurements will begin when
the specified trigger conditions are satisfied following the receipt of the
READ? command. Readings are sent immediately to the output buffer.
You must enter the reading data into your bus controller or the meter
will stop making measurements when the output buffer fills. Readings
are not stored in the meter’s internal memory when using the READ?
command.
Sending the READ? command is like sending the INITiate command
followed immediately by the FETCh? command, except readings are not
buffered internally.
Caution
If you send two query commands without reading the response from the
first, and then attempt to read the second response, you may receive some
data from the first response followed by the complete second response. To
avoid this, do not send a query command without reading the response.
When you cannot avoid this situation, send a device clear before sending
the second query command.
