If the optical signal is low, check to make sure:
• <ul><li><p>The probe and the crystal on its tip is fine.• </p></li><li><p>The operating frequency is correct.• </p></li><li><p>All the components are connected correctly and appropriately.• </p></li><li><p>All instruments are functioning properly.• </p></li><li><p>All cables and the PM fiber are fine.• </p></li><li><p>All connectors are in good conditions – make sure they are not loose. • </p></li><li><p>CPW is functioning properly.• </p></li><li><p>Lower the probe down close to the surface of CPW and make sure the probe positions right above the CPW slot and move it around the slot.
