PROGRAMMER MANUAL
⎯ 23 ⎯
*SAV
Function:
Save the setting data to a specific memory location (The PSS and PSH
series do not have this function).
Syntax:
*SAV
is in the range from 0 through 99.
Examples:
*SAV 01 saves the current setting data to memory location 1.
*SRE
Function:
Set the contents of the Service Request Enable Register (SRER). The
query form returns the contents of the SRER. Bit 6 of the SRER is always
zero. The bits on the SRER correspond to the bits on the SBR.
Syntax:
*SRE
*SRE?
Returns:
is in the range from 0 through 255.
Examples
*SRE 7 sets bits of the SRER to 0000 0111.
If the *SRE? returns 3, the SRER is set to 0000 0011.
*STB? (query only)
Function:
The query of the Status Byte register (SBR) with *STB? will return a

decimal number representing the bits that are set (true) in the status
register.
Syntax:
*STB?
Returns:
is in the range from 0 through 255.
Examples:
*STB? returns 81, if SBR contains the binary value 0101 0001.
*TST? (query only)
Function:
Self-test and test the RAM, ROM.
Syntax:
*TST?
Returns:
0|-300
Examples:
*TST? returns 0, if the test is successful.
*TST? returns –300, if the test is unsuccessful.
*WAI (no query form)
Function:
WAI prevents the programming instrument from executing further
commands or queries until all pending operations are finished.
