Adding the optional CF-0722 Order Ratio Analysis Function makes it possible to perform constant-ratio tracking /
constant-width tracking / time tracking analysis and recording with the rotational data.
You can use the recorded data (ORF file) to perform off-line analysis.
Notes for performing constant-ratio and constant-width order tracking analysis
Constant-ratio order tracking Constant-width order tracking
Tracking analysis is performed by using the rotation pulses obtained from Frequency analysis is performed via an internal sampling clock. Each time the rotational speed
