2. Use a USB cable to connect the EVB to your PC and connect the lab equipment to the EVB.

3. Connect the DGP2 unit to your PC and turn on the unit.

Single-Tone Test

These settings configure the AD9142A to output a sine wave using the DPG2 and allow the user to
view the single-tone performance at the IQMOD output, under the condition: Fdata = 350MHz, 4X
interpolation, IF = 50MHz, LO = 2000MHz, RF = 2050MHz.

1. 1. To begin, open the AD9142A SPI application (Start > All Programs > Analog Devices > SPIPro).
The screen should look similar to Figure 3.

2. Configure the hardware according to the hardware set-up instructions given in the Hardware Setup
section above. Set the frequency of the DAC clock signal generator to 1400MHz, and the output level
to 6dBm. The spectrum analyzer can be configured with Center Frequency = 2050 MHz, Span = 200
MHz, and Resolution Bandwidth of 30 kHz. Choose Input Attenuation to be 24dB. This can be adjusted
later if indications are that the analyzer is causing degradations.

3. Follow the sequence below to configure the AD9142A SPI registers.
