What is the difference between OSCOR Blue and OSCOR Green?

A key technical difference between OSCOR Blue and OSCOR Green is in the functionality of the Trace Data Recorder/Spectrogram feature. OSCOR Green Spectrogram saves intermediate traces at 24.4 kHz resolution every 10 seconds minimum, meaning it provides more detailed snapshots, but less frequently, while the OSCOR Blue Trace Data Recorder saves intermediate traces at 12.2 kHz resolution every 5 seconds minimum, meaning provides less detailed snapshots, but more frequently. The choice depends on your specific needs. If you are dealing with signals that change rapidly and need to capture these changes as they happen, OSCOR Blue might be more suitable. On the other hand, if you need more detailed information about the signals and are less concerned about capturing rapid changes, OSCOR Green might be a better choice for you.
