Questionable Status Group

Questionable Status Group

Register Functions

The Questionable Status registers record signals that indicate abnormal operation of the power supply. As shown in Figure 4-1, the group consists of the same type of registers as the Status Operation group. The outputs of the Questionable Status group are logically-ORed into the QUES(tionable) summary bit (3) of the Status Byte register.

Register Commands

Programming for this group is derived from the STAT:QUES commands described in "Chapter 3 - Language Dictionary" and summarized in Table 4-3.

Table 4-3. Status :Questionable Commands

Standard Event Status Group

Register Functions

This group consists of an Event register and an Enable register that are programmed by common commands. The Standard Event Status Event register latches events relating to interface communication status (see Table 4-1). It is a read-only register that is cleared when read.

Read query	*ESR!
Cleared by	CLS ESR?

The Standard Event Status Enable register functions similarly to the enable registers of the Operation and Questionable status groups.

Register Commands

The common *ESE command programs specific bits in the Standard Event Status Enable register. Because the power supply implements *PSC, the register is cleared at power on if *PSC = 1. *ESR? reads the Standard Event Status Event register and reading the register clears it.
