remote commands.) The SPLSTR is sent to the host over the serial interface when a ^P
(<cntl> P) character is sent. The default format is:
SPL: %02x %02x %04x %04x
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:
SPL: (STB) (ESR) (ISCR0) (ISCR1)
See the commands *STB?, *ESR?, ISCR0?, and ISCR1?. A typical string in the
default format sent to the host is: SPL: 44 00 0000 1000. This command is for
format. For values instead of format, record a ^P (<cntl> p) character. Also see the
SRQSTR command.
Parameter: “<string>\n” (\n represents the NEWLINE character, hex 0A)
Example: SPLSTR “SPL: %02x %02x %04x %04x\n”
Set the SPLSTR to the default values SPL: %02x %02x %04x %04x\n.

(Serial Poll Response String query) Shows the string programmed for Serial Poll
response. For values, record a ^P (<cntl> p) character. Also see the SRQSTR command.
Response: <string>
Example: SRQSTR shows SRQ: %02x %02x %04x %04x\n
Shows the SPLSTR string format (default settings in this example).

(Service Request Enable command) Puts a byte into the Service Request Enable (SRE)
register. (See “Service Request Enable Register (SRE)” in Chapter 5. Since bit 6 is not
used (decimal value 64), the maximum entry is 255 – 64 = 191.
Parameter: <value> (the decimal equivalent of the SRE byte, 0 to 191)
Example: *SRE 56
Enable bits 3 (EAV), 4 (MAV), and 5 (ESR).

(Service Request Enable query) Shows the byte in the Service Request Enable (SRE).

Example: *SRE? shows 56
Shows 56 when bits 3 (EAV), 4 (MAV), and 5 (ESR) are enabled.

(Service Request String command) Sets the Serial Mode SRQ (Service Request)
response (up to 40 characters) in the Calibrator non-volatile memory. (While saving
configuration data in the non-volatile memory, a period of about 2 seconds, the Calibrator
does not respond to remote commands.) The SRQSTR is sent to the host over the serial
interface when the SRQ line is asserted (terminal mode only). Default format is:
SRQ: %02x %02x %04x %04x
