Connecting the Instrument to a Handler with the Handler Interface

Timing Chart

The timing chart in Figure 12-2 shows the timing and duration of each handler signal.

During the interval where /DATA is unknown, no output signal is available because the

4287A is processing the result of analog measurement. For the meanings of T1 through T7

in this chart, see “Specifications and Supplemental Performance Characteristics” in

Operation Manual.

NOTE Design a handler-based auto-sorting system so that the measurement cycle must be

synchronized with the operation status of the 4287A using the status report system or the

timing signals (/READY_FOR_TRIG, /INDEX, or /EOM). Don’t synchronize by inserting

a wait time in the control program for a handler-based auto-sorting system.
