Scope Setup
The Scope Setup function refers to the two BNC connectors located on
the back of the analyzer. BNC-1 will always send out a Sync pulse that
is sensed by the Spark Pickup. BNC-2 will output Secondary Ignition from the KV input or the Primary
Amps from the Black Pickup. The choice is determine by the Scope Setup Software.
You may use either of the signals or both to drive a labscope. Below are a couple of samples of patterns
on different labscopes.
You may also use the BNC-1 signal to trigger the labscope. This will allow you to reference any other
signal to engine rpm.
