Command Details
6
*SRE(?) <value>
Description Loads 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.
Parameters <value>
The decimal equivalent of the SRE byte 0 to 191
Example
*SRE 56
Enable bits 3 (EAV), 4 (MAV), and 5 (ESR).
Query
SRE?
Returns the decimal equivalent of the byte in the
Service Request Enable (SRE).
SRQSTR(?) <text>
Description 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 MSS bit is asserted (terminal mode only).
Default format is:
SRQ: %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:
SRQ: (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: SRQ:
44 00 0000 1000. This command is for format. See the SPLSTR
command for the serial poll response.
Parameters “<string>\n”
Example
(\n represents the Line Feed character, hex 0A)
SRQSTR “SRQ: %02x %02x %04x %04x\n
Sets the SRQSTR to the default values SRQ: %02x %02x %04x
%04x\n.
Query
SRQSTR?
Returns the string programmed for Serial Mode
SRQ response.
*STB?
Description Returns 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?
Returns 72 if bits 3 (EAV) and 6 (MSS) are set.
Description
Deactivates the Calibrator output if it is in operate. This is the same as
pressing Y on the Calibrator front panel.
Response
None
Example
STBY
STBY
Disconnect the selected output from the
Calibrator front-panel terminals.
