FAST 50 Hz QUICK TEST
From the AD719x Evaluation Board Software main window,
click the Fast 50Hz Quick Test button to configure the AD7194
to operate with the fast filter. When the Fast 50Hz Quick Test
button is clicked, the AD7194 is configured to operate with the
fast filter. The software configures the AD7194 to have a gain of
128, the sinc
3
filter is selected with the first sinc filter notch at
800 Hz, and the averaging block is programmed to 16 to place a
notch at 50 Hz. Channel AIN7–AIN8 is selected and REFIN1 is
selected as the reference source. The software also provides
instructions on the link positions for the AD7194 evaluation
board. When the instructions given on each window are
completed, click OK. The AD7194 gathers 100 samples, displays
the results in the waveform, and analyzes the data to calculate
the maximum conversion, minimum conversion, and average
conversion. The rms noise, peak-to-peak noise, and resolution
are also calculated.
