*ESR?
Syntax
*ESR?
Description
Query the event register of the Standard Event Register set.
Explanation The corresponding bits in the event register must be enabled using the *ESE
command. This command queries cand clears the event registerof the Standard
Event Register set.
The definition of each bit in the Standard Event Register is as shown in the table
below. Wherein, bit1 and bit6 are not used and are always regarded as 0. Therefore,
the range of <enable_val> are the decimal numbers corresponding to the binary
numbers ranging from 00000000 (0 in decimal) to 11111111 (255 in decimal) and of
which bit1 and bit6 are 0.

All the commands prior to and including the *OPC
command have been executed.
Return
Format
The query returns an integer that corresponds to the binary-weighted sum of all bits set in
the register. For example, if bit 4 (decimal value = 16) and bit 7 (decimal value = 128) are
enabled, the query will return 144.

*IDN?
Syntax
*IDN?
Description Query the ID string of the instrument (including the manufacturer name, model and
version number).
Return
Format
The query returns the ID string in the form of RIGOL TECHNOLOGIES,M300,<serial
number>,XX.XX.XX.XX.XX.XX.XX
Wherein, <serial number> represents the instrument serial number,
XX.XX.XX.XX.XX.XX.XX represents the instrument software version number.
Example *IDN?
The query returns RIGOL TECHNOLOGIES,M300,M300123123123,07.08.00.01.00.00.17.
