Reading Samples from the ADC
The evaluation board is set up to use the external 5 V on-board
reference (
ADR445
). To read samples from the ADC,
1.
The value in the
Vref
box is set to 5.0000 V by default to
use the external 5 V on-board reference (
ADR445
). If a
different reference is used, such as the 2.5 V internal
reference, set the value in the
Vref
box accordingly. (The
analysis results are based on the value set in this box.)
2.
Select the number of samples to analyze in the
Samples
box. (Note that when performing a continuous capture,
this number is limited to 65,536 samples.)
3.
When
Sampling
is set to
Capture
, a batch of samples is
read when
Start Sampling
is clicked, with the batch size
being set by the value in the
Samples
box. When
Sampling
is set to
Continuous
, the software performs a continuous
capture from the ADC when
Start Sampling
is clicked.
4.
Click
Stop
to stop streaming data.
5.
Use the navigation tools within each graph to control the
cursor, zooming, and panning (see Figure 20).
6.
If desired, save the current captured data for later analysis
(see Figure 24 and the Save File section).
