*SAV — SAVE COMMAND
*SAV
Syntax
:
*SAV <integer> (1 to 99)
Description:
Saves the present state of output voltage and output current to the specified memory location.
This command stores the present state of the power supply to one of 99 memory locations in Flash
Memory (see PAR. 3.6.3.7). The following parameters are stored by *SAV: FUNC:MODE,
VOLT:MODE, CURR:MODE, VOLT:PROT, and CURR:PROT. Settings stored are:
•
Mode of operation (Voltage, Current or External) FUNC:MODE < >
•
Main channel reference type (internal or external) and setting (if internal)
VOLT:MODE < > or CURR:MODE < >, VOLT < > or CURR < >
•
Protection channel reference type (internal or external) and setting (if internal)
VOLT:PROT:MODE < > or CURR:PROT:MODE < >, VOLT:PROT < > or CURR:PROT < >
•
Output status (on or off) OUTP < >
The stored values can be restored by the *RCL command. See PAR. 3.5.2.2 and Figure 3-16 for spe-
cial programming considerations.
A.13
*SRE — SERVICE REQUEST ENABLE COMMAND
*SRE
Syntax
:
*SRE<integer> where <integer> = value from 0 - 255 per Table A-3, except bit 6 cannot be pro-
grammed.
Description:
Sets the condition of the Service Request Enable register.
The Service Request Enable register
determines which events of the Status Byte Register are summed into the MSS (Master Status Sum-
mary) and RQS (Request for Service) bits. RQS is the service request bit that is cleared by a serial
poll, while MSS is not cleared when read. A “1” (1 = set = enable, 0 = reset = disable) in any Service
Request Enable register bit position enables the corresponding Status Byte bit to set the RQS and
MSS bits. All the enabled Service Request Enable register bits then are logically ORed to cause Bit 6
of the Status Byte Register (MSS/RQS) to be set. Related Commands: *SRE?, *STB?. (See exam-
ple, Figure A-1.)
A.14
*SRE? — SERVICE REQUEST ENABLE QUERY
*SRE?
Syntax
:
*SRE?
Response: <integer> = value from 0 - 255 per Table A-3.
Description:
Reads the Service Enable Register.
Used to determine which events of the Status Byte Register are
programmed to cause the power supply to generate a service request (1 = set = function enabled, 0 =
reset = function disabled). Related Commands: *SRE, *STB? (See example, Figure A-1.)
A.15
*STB? — STATUS BYTE REGISTER QUERY
*STB?
Syntax
:
*STB?
Response: <integer> value from 0 to 255 per Table A-3.
Description:
Reads Status Byte Register without clearing it.
This Query reads the Status Byte Register (bit 6 =
MSS) without clearing it (1 = set = function enabled, 0 = reset = function disabled). The register is
cleared only when subsequent action clears all set bits. MSS is set when the power supply has one
ore more reasons for requesting service. (A serial poll also reads the Status Byte Register, except that
bit 6 = RQS, not MSS; and RQS will be reset.) Related Commands: *SRE, *SRE?. (See example, Fig-
ure A-1.)
