Error Messages

Analyzer armed from another module contains no "Arm in from IMB" event

This warning is displayed when a 16715A and newer analyzer machine is in the group run arming tree, armed from another module (not directly from the group run), and no sequencer event list in the analyzer contains an "Arm in from IMB" event or no level in a "Wait for arm in" trigger function.

In this case the analyzer will not wait for the module above it to trigger before it triggers.

Branch expression is too complex

The "Branch expression is too complex" message means that the event list expression for the indicated branch contains more event terms to logically combine than the hardware is capable of combining on a single branch.

Other branches in the sequence may also be too complex. The trigger sequence compiler stops compiling at the first convenient place after it encounters a fatal error.

Because the trigger sequence compiler tries to optimize the event list expression to best fit the capabilities of the hardware, a precise description of the event list limits cannot be easily enumerated, but listed below are some general guidelines for all acquisition modes and some specific suggestions for particular modes.

General Guidelines

Labels that span multiple pod pairs (split labels) greatly increases the compiled hardware expression complexity as compared with labels that are entirely contained within a single pod pair.

Whenever possible try to arrange the probing such that labels to not span pod pairs. This is the single most effective way to reduce the complexity required to implement the event list expression.
