∗LRN?
Sequential command.
Operation complete message generated immediately after <rmt> is sent.
Returns the complete set up of the instrument as a character data block. The block contains a
series of commands, separated by semi-colons, which specify the complete instrument set up
and may thus be returned to the instrument to re-install the set up. The syntax of the response is
The size of the character data block is instrument type dependent.
On the serial interface the response is sent immediately if in non-addressable mode, or when
addressed to talk, if in addressable mode.
The settings in the instrument are not affected by execution of the ∗LRN? command.
∗OPC
Sequential command.
Operation complete message generated immediately after execution.
Sets the Operation Complete bit (bit 0) in the Standard Event Status Register. This will happen
immediately the command is executed because of the sequential nature of all operations.
∗OPC?
Sequential command.
Operation complete message generated immediately after <rmt> is sent.
Query operation complete status. The syntax of the response is
The response will be available immediately the command is executed because of the sequential
nature of all operations.
On the serial interface the response is sent immediately if in non-addressable mode, or when
addressed to talk, if in addressable mode.
∗PRE
<nrf>
Sequential command.
Operation complete message generated immediately after execution.
Set the Parallel Poll Enable Register to the value <nrf>. If the value of <nrf>, after rounding, is
less than 0 or greater than 255 an execution error is generated and error number 200 (Value out
of range) is placed in the Execution Error Register.
∗PRE?
Sequential command.
Operation complete message generated immediately after <rmt> is sent.
Returns the value in the Parallel Poll Enable Register in <nr1> numeric format. The syntax of the
response is
On the serial interface the response is sent immediately if in non-addressable mode, or when
addressed to talk, if in addressable mode.
If the Parallel Poll Enable Register contains 01000001b the response to ∗PRE?
Example.
will be 65<rmt>.
