AVW200 frequency range


TLT Aug 12, 2024 02:41 PM

Hi Everyone,

I have a question about AVW200 frequency range. Is it fine for me to use a widen frequency sweep range than the sensor frequency range. I want to fit two different frequency range sensor (Geokon model 4000: 450Hz to 1250Hz and Geokon model 4450: 1200Hz to 2800Hz) to one same multiplexer. 

I set the begin and end frequency to 450 and 2800 to fit both sensors.

 AVW200 (AVW_Result(1),ComC1,0,200,DST(1,1),1,1,32,450,2800,2,_60Hz,1,0) 

The logger was able to read the sensors and the Hz readings were very close compare to the readings taken with a vibrating wire indicator. My concerns are does it affect the accuracy of the readings? 

Please advise. Thanks.

Regards,

TLT

You are fine using the wider frequency range.

The reason for narrowing a frequency range would be to eliminate a known source of noise.
