4 - 94 COMMAND REFERENCE
The STATus:QUEStionable:PTRansition command sets the contents of the
positive transition filter of the questionable register structure. The positive
transition filter specifies which bits in the questionable condition register, that
make a positive transition (0 -> 1), set the corresponding bit in the questionable
event register. For example, when you set bit 2 in this filter, it will set bit 2 in the
questionable event register at the time bit 2 in the questionable condition register
is set (changed from 0 to 1). After power, on the contents of the negative transition
filter is set to #H7FFF.
The bits have the following value and meaning:
Example:
Send
→ STATus:QUEStionable:CONDition?
Requests for questionable condition.
Read
← 16
The returned value 16 equals bit 4 set (temperature too high/low).
SendÆ STATus:QUEStionable:ENABle 16
Enables report of bit 4 (TEMPerature) in questionable event register.
Send
→ STATus:QUEStionable:NTRansition 0
Disables all bit reports from 1 to 0.
Send
→ STATus:QUEStionable:PTRansition 16
Enables report of "TEMPerature too high/low" (0 -> 1).
Send
→ STATus:QUEStionable:EVENt?
Requests for questionable event.
Read
← 16
The returned value 16 equals bit 4 set (temperature too high/low).
Send
→ STATus:QUEStionable:PTRansition 0
Disables all bit reports from 0 to 1.
Send
→ STATus:QUEStionable:NTRansition 16
Enables report of "TEMPerature within allowed limits" (1 -> 0).
Send
→ STATus:QUEStionable:EVENt?
Requests for questionable event.
Read
← 16
The returned value 16 equals bit 4 set (TEMPerature okay).
