EXAMPLE DATA CAPTURE FOR THE AC SIGNAL

To capture data for the AC signal, take the following steps:
1. Start the ACE Software software. On power-up, the ACE Soft-
ware default sets the input range to IN2, ADC power mode to
fast, and the filter to wideband low ripple with an ODR = 256
ksps.
2. Connect the analog input signal (10.6 V
and use IN2+ and IN2− as the input pins to the
setting the P1 and P2 jumpers (default: IN2, G = 4/11 V/V).
3. To see the result directly, click Run Once (which captures 8192
samples by default).

4. The sampled data is now present in the data capture tabs
(ADAQ7767-1 Board Waveform, ADAQ7767-1 Board Histo-
gram, and ADAQ7767-1 Board FFT). To view the results,
change between each of these tabs. Note that these settings
give a dynamic range of approximately 106 dB, which can be
seen in the Results section of the ADAQ7767-1 Board FFT
tab.
