Constant Q Filter. Minimum
rejection in stopband of -57.7 dB.
Note:
1X & 2X Vector, Not 1X, and Smax
parameters are valid for machine speeds
of 60 cpm to 60,000 cpm. Machines
ramping up from a stop must reach 72
cpm before reaching an OK state.
Accuracy
Direct and Gap
Within ±0.33% of full-scale
typical, ±1% maximum.
1X and 2X
Within ±0.33% of full-scale
typical, ±1% maximum.
Smax
Within ±5% maximum.
Not 1X
±3% for machine speeds less
than 30,000 cpm.
±8.5% for machine speeds
greater than 30,000 cpm.

Spike
User programmable from 0.152 to
8678 Hz.
Element
User programmable for BPFO
ranging from 0.139 to 3836 Hz.
High-pass corner is 0.8x BPFO.
Low-pass corner is 2.2x BPFO.
Rotor
User programmable from 0.108 to
2221 Hz.
Direct
Programmable from 3.906 to 14.2
Hz. Selection is determined by
Spike and Rotor filters.
Gap
Programmable from 0.002 to 1.0
Hz. Selection is determined by the
Rotor filter.
1X Vector filter
The range of shaft speeds for
which the value is valid is
dependent upon the nominal
Shaft Speed for which the
channel is configured. The
following table summarizes the
relationship:
Nominal Shaft
Speed (Hz)
Valid Speed
Range (Hz)
10 to <126
0.071 to 160
126 to <252
0.133 to 330
252 to <504
0.25 to 660
504 to <584
0.50 to 750
Note:
If a multi-event gear or speed wheel
generates the speed input, the resultant
