Filters
Analog Filter
The analog filter is an 8th order Butterworth low-pass fil-
ter (–48 dB/oct). The cutoff frequency can be selected
independently of the sampling frequency. To prevent
aliasing, the cutoff frequency must be set to 50% or less
of the sampling frequency.
Digital Filter
The digital filter using a DSP can attenuate from 40% of
the set sampling frequency. The digital filter is not func-
tional at sampling frequencies of 200 kHz, 100 kHz, and
50 kHz.
■
Calibration
Gain self-calibration using a DSP is performed whenever
power is turned on, and whenever the input range or the
sampling frequency is changed. The signal used for cali-
bration is built into the amp.
Zero Balancing
Perform zero balancing each time you turn on power to
the GX-1. To perform zero balancing, in the parameter
settings dialog box click the Exec button. When you
select All Strain Amp and click Exec, zero balancing
will be simultaneously performed on all channels in the
dynamic strain input amp.
(For zero balancing, set the post trigger to OFF.)
