Assembly and Production Test Procedure for the CN0566 Phaser. Two situations will be described:
1. Install the u.fl cables as shown. Ensure that the connector is aligned before seating, and use a flat surface to press, such as an unused pencil eraser:
2. Install the 40-pin M-F extender on the reverse side of the board. Place the board on stiff antistatic foam while doing this, and use a steady, even pressure.
3. Install a 22 mm M-F standoff and 12 mm M-F standoff as shown below. The threads from the 22 mm standoff enter from the reverse side of the board.
4. Install the camera mount using two 3 mm pan head screws as shown. Do not over-tighten.

6. Prepare the ADALM-Pluto:
7. Mount the ADALM-Pluto from the top side of the board. Note that the threaded ends of the standoff will need to be flexed slightly. Secure with 4x M2.5 nylon nuts. xxx
8. Connect the U.FL cables to the ADALM-Pluto as shown:
Plug a micro HDMI to HDMI cable into the Raspberry Pi HDMI connector closest to the USB-C power input.
Insert a pre-prepared SD card into the Raspberry Pi. (See below for preparation instructions.)
Plug a keyboard into one of the remaining USB ports on the Raspberry Pi (A mouse is optional.)
Connect a 3 Amp USB-C power adapter to the power input on the CN0566. The Raspberry Pi will boot.
Type the following command:
Then press enter. The test script will automatically run and print pass / fail results.

Figure 1. Find HB100 script
Ideally, there should be a single, sharp peak. If there are several peaks or no visible peak, close the plot and enter 'n' at the prompt. Reposition the HB100 (and make sure there are no other sources nearby), then re-run the script. Another method to ensure that the correct source is being identified is to run the script several times, moving the HB100 toward or away from the antenna. The peak should increase and decrease accordingly. Once the correct peak has been identified, enter 'y' at the prompt as shown in Figure 2. This will save the frequency to a calibration file that other scripts and GUIs will read in.
