DAC5688 EVM testing

DAC5688 EVM Equipments 2x Signal Generator with 1GHz output 1x Spectrum analyzer 3x rail power supply with 1.8V, 3.3V, and 5V 4x SMA-SMA cable (2x Gore cable if possible) 1 USB cable 6x Banana to Banana cable 1x TSW3100 board

DAC5688 EVM Connections Supply 1.8V, 3.3V, and 5V to the EVM board through J13/J14, J15/J16 and J10/J11. Connect clock signal generator to J20 through SMA cable (Gore cable preferred). Connect LO signal generator to J23 through SMA cable. Connect Spectrum analyzer to J6 through SMA cable (Gore cable preferred). Connect TSW3100 CMOS clock input (J73 on TSW3100) to J21 of DAC5688 EVM through SMA cable.

Equipment set up Clock source sig gen = MHz with 1.6V of power. LO source sig gen = 2030MHz with 10dBm of power. Spectrum analyzer: –Fc = 2.17GHz –RBW=30kHz, VBW=300kHz, SWT = 2s –CP/ACP stanard = W-CDMA 3GPP FWD –Adjust reference level –Noise correction on
