Arm and Trigger

This section explains some terminology relating the the “Arm” and “Trigger” steps in the measurement loop. As an example a measurement might be set up to arm at a certain RPM level and then subsequently trigger at an external event corresponding to top dead center (TDC). The settings would be:

Arm:	RPM Step Arm
Trigger:	External Trigger

To begin a throughput session at this same RPM/TDC event, then the first external trigger after a specified RPM would start a continuous mode measurement. Now (using overlap block mode) the settings would be:

Pre-Arm:	RPM Step Arm
Arm:	Auto
Trigger:	Auto

In the measurement loop, an arm must take place before a trigger. The number of triggers that occur before waiting for another arm condition can be programmed. The default is one trigger for each arm. For each trigger, a block of data is sent to the host.

The first arm in a measurement is the pre-arm. By default, the pre-arm condition is the same as the regular arm conditions.

Valid Arm (and Pre-Arm) conditions are:

Auto Arm

Manual Arm

RPM Step Arm

Valid trigger conditions are:

Auto Trigger

Input Trigger

Source Trigger

External Trigger

Manual Trigger

Tachometer Edge Trigger
