:STATus:QUEStionable:INSTrument:ISUMmary[<n>]:ENABle
Syntax :STATus:QUEStionable:INSTrument:ISUMmary[<n>]:ENABle <enable value>
:STATus:QUEStionable:INSTrument:ISUMmary[<n>]:ENABle?
Description Enable the bits in the enable register of the channel questionable status SUMMARY
register.
Query the bits currently enabled in the enable register of the channel questionable
status SUMMARY register.
Parameter Name Type Range Default
[<n>] Discrete 1|2|3 None
<enable value> Discrete Refer to the "Explanation" None
Explanation  This command is only applicable to multi-channel models. Multi-channel
models contain multiple channel questionable status SUMMARY registers and
[<n>] represents the questionable status SUMMARY registers of CH1, CH2 and
CH3 respectively when it is 1, 2 and 3. When [<n>] is omitted, the system
queries the enable register of the questionable status SUMMARY register of the
current channel.
 <enable value> is a decimal value corresponding to the sum of the binary
weights of the bits to be enabled in the enable register of the channel
questionable status SUMMARY register. For the definitions of the bits in the
channel questionable status SUMMARY register and their corresponding
decimal values, refer to Table 1-3.
For example, to enable bit0 (Voltage, CC mode) and bit3 (OCP) in the enable
register of the channel questionable status SUMMARY register, set <enable
value> to 9 (according to 2 0 +2 3 =9).
 After the bits in the enable register of the channel questionable status
SUMMARY register are enabled, the system reports the states of the
corresponding bits to the questionable status register.
 When <enable value> is set to 0, executing this command will clear the enable
register of the channel questionable status SUMMARY register.
Return Format The query returns a decimal value corresponding to the sum of the binary weights
of the bits to be enabled in the enable register of the channel questionable status
SUMMARY register, for example, 9.
Example :STAT:QUES:INST:ISUM1:ENAB 9 /*Enable bit0 (Voltage, CC mode) and bit3
(OCP) in the enable register of the CH1
questionable status SUMMARY register*/
:STAT:QUES:INST:ISUM1:ENAB? /*Query the bits enabled in the enable
register of the CH1 questionable status
SUMMARY register and the query returns
9*/
