Chapter 3 Programming Your Counter for Remote Operation

3-34 Programming Guide

Condition Register

A condition register continuously monitors the hardware and firmware

status of the Counter. There is no latching or buffering for this register;

it is updated in real time. Reading a condition register does not change its

contents.

To read the condition registers use:

:STATus:OPERation:CONDition?

:STATus:QUEStionable:CONDition?

Transition Filter

A transition filter specifies the transition criteria for setting event bits TRUE.

When the transition filter specifies a positive transition, the event

becomes TRUE when its associated condition makes a FALSE to TRUE

transition only.

When the transition filter specifies a negative transition, the event

becomes TRUE when its associated condition makes a TRUE to FALSE

transition only.

When the transition filters specify both a positive and a negative

transition, the event becomes TRUE when its associated condition makes

either a FALSE to TRUE or a TRUE to FALSE transition.

A transition filter is defined by positive and negative transition filter

registers. Table 3-6 describes how the transition filter registers define the

transition criteria for setting an event bit TRUE.
