RF INTELLIGENCE / ROLE-BASED CHECKS
Find the next RF test.
Chipset voltages, GR & signals →
Identify the part. Establish its operating state. Measure against the exact board reference.
Device & RF component
Changing the device, part, role or source clears previous results after you apply the change.
UPLOADED SCHEMATIC REFERENCE
Redmi Note 9 · MT6177
The supplied Borneo screenshot shows page 15/30, sheet 31_RF_MT6177_Pin_Out, with Transceiver and Power For MT6177 sections. This supports a board-specific transceiver reference. Small net/pin labels, board revision and numerical readings are not reliably readable in the supplied screenshot; they remain unverified.
Only the device, part role and sheet identity are filled. This does not populate voltage, pin or GR values.
Evidence summary
Use this with your repair case. Recorded test results do not automatically confirm a component or complete a repair.
Measurement sources & limitations
Fluke: diode mode measures voltage drop · Tektronix: probe loading affects measurements
These explain measurement principles, not a specific RF IC pinout or a universal passing value. Use the actual board service documentation for the required nets and operating sequence.
