No Sync Signal Jrc Radar

The modulator board or the trigger generation circuit is defective and requires repair or replacement.

While a failing magnetron usually causes "No Signal" or weak targets, a catastrophic short circuit inside the tube can trip the modulator board's safety logic, suppressing the sync line. 3. Step-by-Step Troubleshooting Guide no sync signal jrc radar

Radar sync errors are often preventable. Follow this JRC-recommended PM (Preventive Maintenance) schedule: The modulator board or the trigger generation circuit

Borrow or buy a handheld oscilloscope (e.g., Fluke 123 or Hantek). the processor cannot construct the image

If this loop is broken, the processor cannot construct the image, resulting in the "No Sync Signal" error. It often appears when the system attempts to turn on the transmitter (TX) after the warm-up period. 2. Preliminary Checks & Safety First
