Sampling Rate of Clarius L7HD3 #13

Open Souganttika opened 1 year ago

Souganttika commented 1 year ago

Hi,

I would like to know what is the sampling frequency/sampling rate of the Clarius L7HD3 scanner and how I can set it to a desirable frequency. Thank you.

Also, is it possible to change the way the timestamps are generated in the RAW data?

what is the preset and depth ranges you are looking at getting the frequency/sampling rate information for, they may vary?

The timestamps are generated from the probe's internal monotonic clock, it cannot be changed.

I am looking at SC Compound mode at a depth of 4cm. The video is recorded for a duration of 5 seconds and the raw IMU data is extracted. Between two recordings of 5 seconds with the same presets, the size of data extracted largely varies. How can that be recified? Stationary_Test_1307_2.zip

Attached are the raw data extracted with the same settings.
