Sample rate of 24 kHz, 3 kHz, and 93.75 Hz defines the
number of samples per second for the three acquisition
frequency bands.
2.
The “Record Length” specifies how long, in seconds, each
time series will be at the specified sample rate.
3.
The “Number of Records” specifies how many time series
will be acquired at each sample rate.
4.
Delay Between Bands (Sec) defines the delay time between
each time series acquired. Each time series is acquired as a
SEG2 file which is converted into a common GTS file for the
survey.
5.
Skip: Checking a skip box allows the operator to not acquire
data in the designated frequency band.
6.
Cycling Acquisition: The acquisition will automatically
continue to cycle through the frequency bands until
acquisition is manually stopped.

Note that you can scroll through a sequence of time series
by using the “enter” and “backspace” keys to go forward or
