Standard Event Status Register Query

*ESR?
Queries and clears the standard event status event register. (This is a
destructive read.)
Range: Integer, 0 to 255
Identification Query
*IDN?
Returns an instrument identification information string. The string will
contain the model number, serial number and firmware revision. The
response is organized into four fields separated by commas. The field
definitions are as follows:
Manufacturer
Model
Serial number
Firmware version
For example:
Hewlett-Packard, E4401B, US00000013, A.00.00

Instrument State Query

*LRN?
Returns current instrument state data in a block of defined length. The
information is in a machine readable format only. Sending the query
returns the following format:
SYST:SET #NMMM<state_data>
The following example is a response to *LRN? The actual sizes will vary
depending on the instrument state data size.
Example:
#42031SYST:SET #42016<state data>
4 (N in the preceding query response format) represents the number of bits
to follow
2031 and 2016 (MMM in the preceding query response format) represents
file size in bytes
The state can be changed by sending this block of data to the
instrument after removing the size information:
SYST:SET #NMMM<state_data>
