STAT:QUES NTR

STAT:QUES PTR

These commands allow you to set or read the value of the Questionable NTR (Negative-Transition) and PTR (Positive- Transistion) registers. These registers serve as polarity filters between the Questionable Enable and Questionable Event registers to cause the following actions:

•When a bit of the Questionable NTR register is set to 1, then a 1-to-0 transition of the corresponding bit of the Questionable Condition register causes that bit in the Questionable Event register to be set.

•When a bit of 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.

•If the same bits in both NTR and PTR registers are set to 1, then any transition of that bit at the Questionable Condition register sets the corresponding bit in the Questionable Event register.

•If the same bits in both NTR and PTR registers are set to 0, then no transition of that bit at the Questionable Condition register can set the corresponding bit in the Questionable Event register.

Note	Setting a bit in the PTR or NTR filter can of itself generate positive or negative events in the
	corresponding Questionable Event register.

System Commands

SYST:ERR?

This query returns the next error number followed by its corresponding error message string from the remote programming error queue. The queue is a FIFO (first-in, first-out) buffer that stores errors as they occur. As it is read, each error is removed from the queue. When all errors have been read, the query returns 0,NO ERROR. If more errors are accumulated than the queue can hold, the last error in the queue will be -350,TOO MANY ERRORS (see Table 5-1 in "Chapter 5 - Error Messages" for other error codes).

You can use the power supply front panel key to read errors from the queue. Errors generated at the front panel are not put into the queue but appear immediately on the display.
