Crystal troubleshooting

Introduction

26 MHz Reference Oscillator (VCXO)

The 26 MHz oscillator is located near the UPPCosto IC (D7402). The coarse frequency for this oscillator is set

by an external crystal (B7402).
The 26 MHz signal from the crystal can be measured by probing C7436. The level at this point is approx.

276mVpp. Example Signal Measured at VCXO output (C7436).
