STATus:QUEStionable:PTRansition
Syntax
STATus:QUEStionable:PTRansition <value>
This register serves as a polarity filter between the Questionable Condition and 
Questionable Event registers. When a bit in the Questionable PTR register is set  
to 1, then a 0-to-1 transition of the corresponding bit in the Questionable 
Condition register causes that bit in the Questionable Event register to be set.
STATus:QUEStionable:PTRansition? 
These command reads the value of the Questionable PTR (Positive-Transition) 
register. 
Parameter
For example, to enable bit 4, the corresponding decimal value would be 16.
Remarks
– The following table lists the bit definitions for the Questionable Status 
registers.
–The STATus:PRESet command will set all bits in the PTR register to 1. 
For more information on the SCPI Status System, refer to Chapter 2, “Status 
system diagram” on page 21.
Item Type Range of values Defaul t value
