TP1 to TP7) To verify the ADS1202EVM is functional, arrange W1 and W2 for Mode 0 operation by ensuring the shunt jumpers are installed (factory default conditions). Apply 5-V power to the EVM through J3. Apply a 200-kHz sinusoidal wave (250 mV ) to J1.2 referenced to J1.4. - Page 14 All manuals and user guides at all-guidesbox.com Using an oscilloscope view the MCLK and MDAT output signals on J2.5 and J2.13 respectively. The outputs should look similar to those in the following figure: Slowly increase the time base of the oscilloscope. As the time base increases, the sine wave applied to the input terminals should begin to appear on the oscilloscope screen as shown below.
