Switch Label Function Sync1 Sync2 Disable Boot Select Reset Controls DUT pin 19 “SYNC1 control” Controls DUT pin 20 “SYNC2 control” Controls DUT pin 21 (/Disable) Controls DUT pin 8 (/Bootsel) - Only used for Wi125 software updates/revisions Controls DUT pin 10 (/Reset) 3) Connect the BNCs (center positive) • Do not apply voltages higher than indicated or the DUT and/or test board could be damaged. • Connect 3.3V to J1 to power the test board. • Connect 3.3V to both J2 and J3 to power the FTS125. Use separate supplies for J2 “DUT Vcc1” and J3 “DUT Vcc2” otherwise phase noise performance will be degraded. • Connect 3-12V to J4 to power an active antenna through the FTS125's MCX antenna connector. If a different antenna is used other than that supplied with the FTS125 Eval Board, consult that antenna's documentation for the required voltage.

An antenna fault condition is defined as an overcurrent on DUT Pin 14 (Antenna Supply Voltage). This fault status is self-clearing once the fault condition goes away. • Holdover Status (D6) Amber LED turns on if the unit is in automatic or forced holdover as indicated by DUT Pin 23 “Holdover Status”. • Lock Status (D5) Green LED turns on if the unit is tightly locked to the selected input as indicated by DUT Pin 24 “Lock Status”.
