Chapter 4 Command Reference

:STATus Subsystem

∙This value is unaffected by *RST and save/recall.

:STATus:PRESet

This event command presets the enable registers and transition filters associated with the Operation and Questionable status reporting structures. The enable registers and negative transition filters are preset such that each bit is a 0 (FALSE). The positive transition filters are preset such that each bit is a 1 (TRUE).

:STATus:QUEStionable Subtree

The :STATus:QUEStionable subtree commands allow you to examine the status of the Counter monitored by the Questionable Data/Signal Status Register group, shown in Figure 4-3. The Questionable Status group consists of a condition register, two transition registers, an event register, and an enable register. The commands in this subtree allow you to control and monitor these registers.

See the section titled “Operation Status Register Group and Questionable Data/Signal Status Register Group” on page 3- 32 in Chapter 3 for a detailed description of the Questionable Data/Signal Status Register Group.
