These tests are meant as a tool +for Ettus R&D to enable faster and more reliable development. Note these tests +are no replacement for manufacturing or production tests, and should not be +treated as such. Instead, they are meant to catch common failure modes during +development. As a result, test definitions are fairly light-weight. + +\section rdtesting_phase Phase Alignment Tests + +tbd + +\section rdtesting_gpsdo GPSDO Tests + +| Test Code | Device | Peripherals | Manual Test Procedure | Automatic Test Procedure | +|------------------|-----------|-------------------|------------------------------|---------------------------| +| GPS-X310-TCXO-v1 | USRP X310 | Jackson Labs TCXO | \ref rdtesting_gpsdo_manual | \ref rdtesting_gpsdo_auto | +| GPS-X310-OCXO-v1 | USRP X310 | Jackson Labs OCXO | \ref rdtesting_gpsdo_manual | \ref rdtesting_gpsdo_auto | +| GPS-X300-TCXO-v1 | USRP X300 | Jackson Labs TCXO | \ref rdtesting_gpsdo_manual | \ref rdtesting_gpsdo_auto | +| GPS-X300-OCXO-v1 | USRP X300 | Jackson Labs OCXO | \ref rdtesting_gpsdo_manual | \ref rdtesting_gpsdo_auto | +| GPS-B200-TCXO-v1 | USRP B200 | Jackson Labs TCXO | \ref rdtesting_gpsdo_manual | \ref rdtesting_gpsdo_auto | +| GPS-B210-TCXO-v1 | USRP B210 | Jackson Labs TCXO | \ref rdtesting_gpsdo_manual | \ref rdtesting_gpsdo_auto | + + +\subsection rdtesting_gpsdo_recommendations Recommendations + +For cursory testing, not all tests within a device family are required (e.g., +only testing the OCXO on any X-Series, and testing the TCXO on any B-Series is +sufficient). + +The following tests are recommended for a minimum test (N stands for the latest +version of this test): +- One of GPS-X310-OCXO-vN or GPS-X300-OCXO-vN +- One of GPS-B210-TCXO-vN or GPS-B200-TCXO-vN + +\subsection rdtesting_gpsdo_requirements Requirements + +All of these tests require a device that is GPSDO capable (e.g., X3x0, B2x0, +N2x0). For those devices that have a separate GPS component (such as the Jackson +Labs GPSDOs), this component is also required (called the "peripheral" in the +following). + +\subsection rdtesting_gpsdo_manual GPSDO: Manual Test Procedure + +1. Without connecting the peripheral to the device, run `uhd_usrp_probe` on the + device and verify that the lack of GPSDO is correctly reported. No warning + or error must be printed. +2. This and the following tests are run with the peripheral connected: Run + `uhd_usrp_probe` and verify that the GPSDO is correctly reported. Power down + the device before connecting the peripheral. The GPSDO must be reported + found, and no error or warning must be printed. +3. Without connecting the GPS antenna input, run `query_gpsdo_sensors`. To pass, + it must report the GPSDO as found, lock to the external reference, but then + report not being locked to GPS. The tool will report a valid GPS time, and + a string such as "GPS and UHD Device time are aligned" in case of success. +4. Connect a GPS antenna to the input and make sure it is in a position to + receive GPS satellite data. Confirm that GPS lock is reported using + `query_gpsdo_sensors` within 20 minutes of connecting the antenna. + The tool `query_gpsdo_sensors` will print a string such as "GPS Locked" in + case of success. + +All of these tests must pass for a 'pass' validation. + +\subsection rdtesting_gpsdo_auto GPSDO: Automatic Test Procedure + +tbd + +\section rdtesting_defining Defining R&D Tests + +Tests can be added any time to define procedures for pass/fail validation. Any +test must include the following: + +- An unambiguous test code. This code consists of three characters that + identify the test, a short description of the devices required, and a version + suffix. Example: `GPS-X310-OCXO-v1` is a GPS-related test, requires an X310 + and an OCXO to run, and is version 1 of this test. +- A manual testing procedure. This must unambiguously define a set of tasks, + and clearly identify whether or not a test has failed or passed. Tests do not + require any other defined outcome other than 'pass' and 'fail'. +- Optional, but highly recommended: An automatic test procedure. This must + consist of a command, or a script, or a set of commands that can be + automatically executed, and that will report a failure condition by means of + returning a non-zero return value. + +Basic understanding of the operation of USRPs by the test operator should be +assumed when authoring test procedures. The descriptions should be as short as +possible to fully describe, unambiguously, how to reach a pass/fail conclusion. + +Test procedures may be updated at any time. If this happens, a new test code +must be generated, with the version number increased. Old test codes are +considered deprecated (if there exists a version 2 of a test, version 1 should +not be run any more). + +*/ +// vim:ft=doxygen: |
