4.3 MacTalk Scope usage
4.3.4 Scope trigger setup
The scope trigger is rather complex with many possible configurations.
First you have to make a trigger selection.
Never (Run continuous, no trigger:
The default mode where no data is captured.
The purpose of this mode is to be able to load previous scope data for preview.
Always (Single shot):
Capture data directly after Start without any trigger condition.
Compare register against value:
Capture will start when a register value meets the described condition.
Possible comparison selection is: ‘=’, ‘!=’, ‘>’, ‘>=’, ‘<‘ or ‘<=’.
A typical scenario: Trigger recording of data, when the Actual velocity exceeds 1000rpm
Compare register against register:
Same as above, but where value is the contents of another register.
Possible comparison selection is: ‘=’, ‘!=’, ‘>’, ‘>=’, ‘<‘ or ‘<=’.
A typical scenario: Trigger recording of data when the Regenerative load = Regenerative
load limit.
Register is within threshold:
Capture will start when a register value meets the described condition.
A typical scenario: Trigger recording of data, when the Actual velocity is inside the range
900rpm to 1000rpm
Register is exceeds threshold:
Capture will start when a register value meets the described condition.
A typical scenario: Trigger recording of data, when the Actual velocity is outside the range
900rpm to 1000rpm
Bit condition:
Capture will start when a bit in a register changes to High or Low.
A typical scenario: Trigger recording of data, when Error/status Bit 24 is set or reset.
Do NOT capture data
Capture will start when a register meets the described condition
Capture will start when the register comparison is true
Capture will start when a register is inside the described range
Capture will start when a register is outside the described range
Capture will start when the bit in the register is High or Low
