Evaluation Kit (EVK) User’s Manual
Hardware Operation
The following steps prepare the evaluation solution for power up and making measurements. Please follow the
guidelines and verify the connections with the supplied schematic before applying power.
1) Verify all DC power supplies are turned off before proceeding.
2) Calibrate board trace loss with THRU trace test coupon between J4 and J5. THRU calibration is sufficient for
initial measurements. Use one-half the loss of the measured trace, as this will de-embed one connector and
half the trace. If more accurate results are desired, a full vector de-embedding can be done with the THRU
trace that matches your de-embedding technique
.
3) Provide external power supply for V
DD
on HDR-3 pin 4, GND on HDR-3 pin 2, and VDD_DIG on HDR-3 pin 3.
4) Ensure switch P/S (parallel/serial) switch position matches the desired control type used through the PC soft-
ware (parallel/serial) or manual control (parallel).
5) Move switches D0–D6 and LE to the center position "EXT" when using the PC software and USB interface
board to control the DSA.
6) When controlling the DSA without the PC software and USB interface board, use switches D0–D6 and LE to
positions HIGH and LOW to set the desired digital input.

Notes:
1) This voltage is named VDD_DIG on EVK HDR-3 pin 3 and is used to manually set a logic “1” when using D0–D6and LE to force the logic levels.
The Peregrine dongle is a 2.5V logic device.
