+# CN0534 Production Script
+This is version 1 of the CN0534 production test which uses Pluto as the test platform.
+
+The main script is based on the `power_check.c` script found on the [plutosdr_scripts repository](https://github.com/analogdevicesinc/plutosdr_scripts) with modifications to accommodate features to test of CN0534.
+
+Running first the build script is necessary. Prior to running, set the build environment first in the `./build_arm.sh`, change the CC_DIR to the path of the bin folder of the compiler.
+
+For Linux, with the cross compiler set on the host pc and linked with the sysroot used by the pluto, run `./build_arm.sh`. The sysroot used should match to the firmware of pluto. As of this writing, pluto firmware v0.30 is used. The sysroot folder should be in the same directory as the `./build_arm.sh`. Also, [updating Pluto to AD9364 frequency range](https://wiki.analog.com/university/tools/pluto/users/customizing#updating_to_the_ad9364) is necessary to accommodate CN0534 frequency range.
+
+![Build Folder Structure](images/build_folder_structure.png)
+
+With this build, the binary file can now be stored in a flash drive together with the `runme0.sh` and `parameters.txt`. And upon pluto power up, the binary test file automatically starts and the test is now running.
+
+![Flashdrive files](images/Flashdrive_files.png)
+
+What this script will do:
+1.  Get test parameters from parameters.txt.
+2.	Run test in every test line.
+3.	Frequency and scale is set on Pluto and the received signal is measured.
+4.	The test checks for frequency tolerance, sfdr, RSSI and peak power.
+5.  CN0534 DS2 (red LED) should turn on once during the test. 
+6.	After execution of the test, LED1 will be Solid ON if the EVAL CN0534-EBZ passes the necessary tests. .
+7.	If an error happens, or invalid measurements persist 3 retries, LED1 will be turned OFF if the EVAL-CN0534-EBZ fails the tests
