5.4.1.5.9.4 MaxFrequencyEnvelopeRead
Name:
MaxFrequencyEnvelope01Read
This register is used to read the configured maximum frequency for the individual channels' envelope signal.

Values
UINT
0 to 65,535
5.4.1.5.9.5 MaxFrequencyRaw
Name:
MaxFrequencyRaw01
Registers for setting the maximum frequency of the channel. Reducing the maximum frequency allows the fre-
quency resolution in the spectrum to be increased.

Important information for configuring the maximum frequency
•
The frequency range must be larger than the damage frequency but should otherwise be kept as small as
possible in order to achieve a good resolution.
•
When using broadband values (e.g. PeakRaw), only the largest peak value is returned during a measure-
ment. Using a longer measurement time at a lower frequency can lead to the measured value being over-
looked in some applications.
•
The maximum frequency influences the size of the sampling rate and can be configured using register
"AnalogInput" on page 165
.
