Using Status Reporting Commands
SYSTem:ERRor?
Description Retrieves errors from the Meter’s error queue. Errors are retrieved in first-
in, first-out (FIFO) order. Each error may contain up to 80 characters.
Examples SYST:ERR? Returns the next error in the error queue.
Performing a SYST:ERR? command when the
error queue is empty causes +0,″No error″ to be
returned.
STATus:QUEStionable:ENABle(?) <n>
Description Enables or disables bits in the Meter’s Questionable Data enable register.
Parameters <n> = 0 to 65535 Binary-weighted decimal value representing the
bits to set in the register. Although a 16-bit
register that will accept a number between 0 and
65535, only bits 0, 1, 9, 11, 12, and 13 are used.
Examples STAT:QUES:ENAB 4 Sets bit 2 to one and all others to zero.
Query STAT:QUES:ENAB? Retrieves a binary-weighted decimal value
representing the bits set in the questionable data
enable register.
STATus:QUEStionable:EVENt?
Description Enables or disables bits in the Meter’s Questionable Data event register.
Parameters <n> = 0 to 65535 Binary-weighted decimal value representing the
bits to set in the register. Although a 16-bit
register that will accept a number between 0 and
65535, only bits 0, 1, 9, 11, 12, and 13 are used.
Query STAT:QUES:ENAB? Retrieves a binary-weighted decimal value
representing the bits set in the questionable data
event register.
STATus:PRESet
Description Sets all bits to zero in the Meter’s Questionable Data enable register.
Examples STAT:PRES Sets all bits to zero.
*CLS
Description Sets all bits to zero in the Meter’s status byte register and all event
registers. Also clears the error queue.
Examples *CLS Sets all bits to zero and clear error queue.
