Correct me if i am wrong, but isn't the power bar on an Odyssey spectrum the summation of what is under the spectrum from min to max freq of that spectrum. Also that the overall is a over all reading from Zero to infinity. Please corect me if i am wrong.

Marshall

The very first analyzer with infinite frequency response! That just blows away PeakVue, Ultrasound, Shock Pulse and Acoustic Emissions!

actually i think it was from 0-5000 hz

Here's how I understand it: (from the Enpac help file)___________________________________________

· Overall - Typically this filter maps to a specific high pass filter in the data collector and is available for magnitude, spectrum, and time waveform measurements. In the Enpac, it maps to the Enpac filters shown in the table below, depending on the results of comparing the filter choice to the formula below.

EMONITOR Odyssey or Enshare uses the following formula:

2 * fmax / # lines

EMONITOR Odyssey or Enshare uses an overall filter with one of the low frequency cutoffs shown in the table below. It uses the filter whose cutoff is greater than or equal to the result of the formula.

Integrated (A to V, A to D, V to D) Non-integrated (A, V, and D)
0.36 Hz (21.6 CPM) 0.18 Hz (10.8 CPM)
5.30 Hz (318 CPM) 2.67 Hz (160.2 CPM)
23.80 Hz (1428 CPM)

For example:

EMONITOR Odyssey or Enshare uses the 5.30 Hz (318 CPM) filter for an integrated measurement. It uses the 2.67 Hz (160.2 CPM) filter for a non-integrated measurement.

* * * Additionally, we have seen varying results based upon using software filters that do not line up with available hardware filters in the data collector.
