COMMAND REFERENCE 4 - 91
The STATus:OPERation:PTRansition command sets the contents of the positive
transition filter of the operation register structure. The positive transition filter
specifies which bits in the operation condition register, that make a positive
transition (0 -> 1), set the corresponding bit in the operation event register. For
example, when you set bit 2 in this filter, it will set bit 2 in the operation event
register at the time bit 2 in the operation 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:OPERation:CONDition?
Requests for operational condition.
Read
← 4
The returned value 4 equals bit 2 set (instrument is currently autoranging).
Send
→ STATus:OPERation:ENABle 4
Enables report of bit 2 (RANGing) in operational event register.
Send
→ STATus:OPERation:NTRansition 0
Disables all bit reports from 1 to 0.
Send
→ STATus:OPERation:PTRansition 4
Enables report of "Autoranging started" (0 -> 1).
Send
→ STATus:OPERation:EVENt?
Requests for operational event.
Read
← 4
The returned value 4 equals bit 2 set (instrument has started autoranging).
Send
→ STATus:OPERation:PTRansition 0
Disables all bit reports from 0 to 1.
Send
→ STATus:OPERation:NTRansition 4
Enables report of "Autoranging stopped" (1 -> 0).
Send
→ STATus:OPERation:EVENt?
Requests for operational event.
Read
← 4
The returned value 4 equals bit 2 set (instrument has stopped autoranging).
