*SRE <enable value>
*SRE?
Enables bits in the Status Byte enable register. The query returns the decimal value corresponding to the
binary-weighted sum of all bits set in the register.
*STB?
Queries the Status Byte summary register. This is similar to a serial poll but it is processed like any other
instrument command. The *STB? command returns the same result as a serial poll but the “Request
Service” bit (bit 6) is not cleared if a serial poll has occurred.
*TRG
Generates an event trigger to the trigger system when the trigger system has a BUS (software) trigger as
its trigger source (TRIG:SOUR BUS). If the trigger system is not initiated, the *TRG command is simply
ignored.
*TST?
Performs a complete self-test of the power supply and returns “0” (pass) or a non-zero value (fail). If the
self-test fails, an error message is also generated with additional information on why the test failed.
The bits added together to produce a non-zero value in the case of a failing self-test are shown below.
Bit Value Name Description
0 1 EEPROMstatus
1 2 Voltage monitor for +15 V
2 4 Model number detection failure
3 8 (unused) (reserved for future use)
4 16 (unused) (reserved for future use)
5 32 ADC failure
6 64 DAC failure
7 128 (unused) (reserved for future use)
*WAI
Waits for all pending operations to complete before executing any additional remote interface
commands. This command is used only in the triggered mode to wait for a pending delayed trigger.
