Hardware
•
Apply an analog signal (2.51 MHz, –10 dBm) to any analog input SMA.
•
The CW outputs (J12, J13) display the frequency I and Q signals at 10 kHz as shown in
The GUI Gain Control Feedback Resistor can vary the amplitude of the outputs.

VControl
Switch between using the onboard Vcntl or the external Vcntl by using JP15. External Vcntl can range
from 0 V to 1.5 V. If using the external Vcntl, then a DC voltage source must be connected to J14. The
default setup uses onboard Vcntl. VR2 is used to make onboard Vcntl adjustments.

4.10 Serial Interface
The serial interface of the board is located on the bottom right-hand side. USB1 is the USB interface
connector. P13 and P14 are test points for the USB data bus: From pin 1 to pin 9, the signals are D0, D4,
D2, D1, D7, D5, D6, D3, and DGND. P14 on the VCA5807EVM is not installed.
