:STATus Subsystem
4-110 Programming Guide
• At power-on and STAT:PRES, the positive transition filter is preset such that
each bit is a 1 (TRUE).
• 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.
