STAT:QUES[:EVEN]?
Purpose
QUES?
returns the contents of the Questionable Event register, clearing the register.
Response
A
<DNPD>
in the form of an Nr1 number is returned. The value of the number, when converted to base 2 (binary), identifies the
Questionable Event register bits to determine their current status.
For example (refer to Fig. 6.2):
If an error had been initiated by an incorrect constant current during Resistance operations, the 'sticky' 'INV OHM CURR1 ' bit
9 of the register would be set, and if no other Questionable Event bits were enabled, the number
512
would be returned. Bit
9 (indeed, all bits in the register) would be reset by this query.
6.6.5.6
STAT:QUES:ENAB(?)
<DNPD>
Purpose
QUES:ENAB <DNPD>
sets the mask which enables those Questionable Event register bits which are required to be summarized
at bit 3 of the IEEE 488.2 Status Byte register.
<DNPD>
This is a decimal integer whose binary equivalent represents the bits required to be enabled.
For example (refer to Fig. 6.2):
The command:
QUES:ENAB 1536
would be required to enable only the 'INV OHM CURR1' and 'INV OHM CURR2' bits
9 and 10 of the Questionable Event register.
Response to the Query Version
A
<DNPD>
in the form of an Nr1 number is returned. The value of the number, when converted to base 2 (binary), identifies the
bits set in the Questionable Enable mask.
For example (refer to Fig. 6.2):
If the 'INV OHM CURR1' bit 9 of the register is the only enabled bit, the number
512
would be returned.
