The following instructions are a step-by-step
guide for connecting the ADS9308V8IEVM to the computer and evaluating the performance of the
ADS9308V8I.
- Review the default jumper settings in
Figure 2-1 and the power guidelines
in Section 2.4.1.
-
IMPORTANT: Please set the J5
jumper on the TSWDC155EVM to the +1.8V option.
- Physically connect J1 of the TSWDC155EVM
to J22 of the ADS9308V8IEVM. This component is the digital communications and power signal
connection in default configuration.
- Set jumper JP1 to the FMC_PWR position so
the TSWDC155EVM provides power. Otherwise, set JP1 to EXT_PWR and connect an external 5.2V
to 5.5V supply on screw terminal connection J7.
- Bypass any external USB hub and connect
the USB on the TSWDC155EVM directly to the computer.
- Install the GUI as described in Section 3.1.
- Install the necessary USB drivers as
described in Section 3.1.1.
- Launch the GUI.
- For ADS9308V8IEVM and GUI, press the
Board Startup and Initialize Device buttons, in order, on the
Configuration tab to power up and configure the EVM, (see Section 3.2.1 for details).
- Connect a 40mVPP, differential sine wave signal from a
function generator to any current sense channel (CH1 - CH8 on EVM) through the J1 header
or connect a 9VPP, differential sine wave signal to any voltage sense channel
(CH9 - CH16 on EVM) through the J2 header.
- Select the number of samples to be at
least 32k points, and choose the Hanning window type for best frequency domain
results.
- Press the Start Capture button to
collect and analyze the data displayed on the appropriate channel; see Section 3.2 for more details.
