where the term %02x (8 bits) means print the value in hexadecimal with 2 hex digits, and
%04x (16 bits) means print the value in hexadecimal with 4 hex digits. The string
representations are:
SRQ: (STB) (ESR) (ISCR0) (ISCR1)
See the commands *STB?, *ESR?, ISCR0?, and ISCR1? A typical string in the
default format sent to the host is: SRQ: 44 00 0000 1000. This command is for
format. See the SPLSTR command for the serial poll response.
Parameter: “<string>\n” (\n represents the Line Feed character, hex 0A)
Example: SRQSTR “SRQ: %02x %02x %04x %04x\n”
Set the SRQSTR to the default values SRQ: %02x %02x %04x %04x\n.

(Service Request String query) Shows the string programmed for Serial Mode SRQ
response. This is the format of the Service Request String; actual values come from the
registers. Also see the SPLSTR command.
Response: <string>
Example: SRQSTR shows SRQ: %02x %02x %04x %04x\n
Shows the SRQSTR string format (default settings in this example).

(Status Byte Register query) Shows the byte for the Status Byte Register. (See “Status
Byte Register (STB)” in Chapter 5.)
Response: <value> (the decimal equivalent of the STB byte, 0 to 255)
Example: *STB? shows 72
Shows 72 if bits 3 (EAV) and 6 (MSS) are set.

(Standby command) Deactivates the Calibrator output if it is in operate. This is the same
as if you push the Calibrator front panel key.
Parameter: (None)
Example: STBY
Disconnect the selected output from the Calibrator front panel terminals.
