(Serial Poll String command) Set the Serial Poll String (string up to 40 characters)
which is saved in the 5500A non-volatile memory. (While saving configuration data in
the non-volatile memory, a period of about 2 seconds, the 5500A does not respond to
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 exactly 2 hex
digits, and %04x (16 bits) means print the value in hexadecimal with exactly 4 hex
digits. The string representations are:
SPL: (STB) (ESR) (ISCR0) (ISCR1)
See the commands, respectively, *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, enter 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) Return the string programmed for Serial Poll
response. For values, enter a ^P (<cntl> p) character. Also see the SRQSTR command.
Response: <string>
Example: SRQSTR returns SRQ: %02x %02x %04x %04x\n
Return the SPLSTR string format (default settings in this example).

(Source Preference command) Set the source preference to 5500A Calibrator or 5725A
Amplifier, when a 5725A Amplifier is attached, which is saved in the 5500A non-
volatile memory. (While saving configuration data in the non-volatile memory, a period
of about 2 seconds, the 5500A does not respond to remote commands.) Source
preference is used when an output value is programmed to a value that can be sourced by
both the 5500A Calibrator and the 5725A Amplifier.
Parameters: P5500 (5500A Calibrator is the source preference)
P5725 (5725A Amplifier is the source preference)
Example: SRC_PREF P5725
Set the source preference to the 5725A Amplifier.
