Panther can perform tracked frequency tests, which are very useful for applications like Rotating Machinery Analysis. It uses a High Precision Frequency Track (HPFT) channel to precisely follow the signal's frequency changes. This digital tracking is more accurate than older analog methods and ensures that your analysis is based on a very stable frequency reference.

High Precision Frequency Track, or HPFT, is essentially a digital channel that works hand-in-hand with Panther's input and output systems. It dynamically adjusts the sampling rate to precisely follow the signal's frequency in real-time.

This is very important for things like Sine Analysis because it means you get a much more accurate and stable frequency reference compared to older analog methods that relied on COLA signals. This HPFT channel can be saved along with your test data in a time domain based stream file, which is crucial if you need to do any post-processing or analysis later using the Sine Analysis application. It ensures that all your analysis is based on a very accurate representation of the frequency content.
