eONE Controls - HS version
Note:
The sampling rate is limited up to 20 kHz in
the Base and VP version.
Note:
Users can achieve a large variety of effec-
tive signal bandwidth using different com-
binations of the SR and Final Bandwidth
controls. For example, selecting a sampling
rate of 20 kHz and a Final Bandwidth of
SR/20 (or a 10 kHz and a Final Bandwidth
of SR/10), a 1 kHz bandwidth can be ob-
tained.

eONE Controls
The eONE Controls window contains controls in a modular fashion with some fea-
tures enabled or disabled depending on the eONE version. Below is described the
HS version control tab which include all the possible features.
The
Controls
tab
contains the following controls:
Range
Sampling Rate (SR)
Final Bandwidth
Digital Compensation
eONE reset
The
Range
buttons enable the users to choose between two ranges:
from -200 pA to +200 pA
or
from -20 nA to + 20 nA
The
Sampling Rate (SR)
buttons enable the users to choose between the differ-
ent sampling rate values up to 200 kHz (for the HS version), respectively:
1.25 kHz
5 kHz
10 kHz
20 kHz
40 kHz
50 kHz
100 kHz
200 kHz
The
Final Bandwidth
buttons enable the users to select the final signal bandwidth
between four different digital filters settings:
Sampling Rate/2, the Nyquist frequency
Sampling Rate/8
Sampling Rate/10
SamplingRate/20
