5 Troubleshooting
If the
D1 LED is not illuminated:
• Ensure J12 jumper is installed (shunt 2-3)
• Ensure mini-USB cable is securely connected to J19
If HSDC Pro does not successfully capture data:
• Ensure that the sampling clock is present at J2 of the
• Ensure that the TSW1400EVM has at least 3 A of current available on its 5-V power supply
• Push the S1 button on the
to reset ADC, and restore default settings

6.1 Analog Input Configuration
By default, the analog input for the
is configured for an AC-coupled, balun signal chain. For best
spurious performance, the input frequency should be above 2 MHz.
For DC-coupled inputs, and those below 2 MHz, the FDA input path should be utilized. This can be done by
making the following modifications to the EVM:
• DNI: R116, R118, R119, R120, C81, C84
• Install: C79 (use 0-Ω resistor for DC coupled input), R115, R122, and R134
• C88 and C92 may be bypassed (short with 0-Ω resistor) to create DC ground.
Once these modifications are performed, the analog input must be connected to J10.
