*SAV <0-9>
Saves the instrument state to one of ten non-volatile memory locations. For safety reasons, when a
saved state is recalled, the output state will be set to OFF.
Parameter
0 - 9
Save state to location 1: *SAV 1
If a particular state is desired at power-on, it should be stored in location 0. Location 0 is auto-
l
matically recalled at power turn-on when the Output Power-On state is set to RCL 0.
Output state, List data, and the calibration state is NOT saved as part of the *SAV operation.
l
Data saved in non-volatile memory, described under
l
*SAV command.
When shipped, locations 0 through 9 are empty.
l
*SRE <value>
*SRE?
Service request enable command and query. This sets the value of the Service Request Enable
register. This determines which bits from the
Status Summary (MSS) bit and the Request for Service (RQS) summary bit. A 1 in any Service Request
Enable register bit position enables the corresponding Status Byte register bit. All such enabled bits
are then logically OR-ed to cause the MSS bit of the Status Byte register to be set. Refer to
Tutorial
for more information.
Parameter
A decimal value corresponding to the binary-weighted
sum of the register's bits.
Enable bit 3 and bit 4 in the enable register: *SRE 24
When a serial poll is conducted in response to SRQ, the RQS bit is cleared, but the MSS bit is not.
l
When *SRE is cleared (by programming it with 0), the power supply cannot generate an SRQ.
*STB?
Status byte query. Reads the
Output Queue MAV bit. The Status Byte is a read-only register and the bits are not cleared when it is
read. Refer to
Status Tutorial
Parameter
(none)
Read status byte: *STB?
