Common RF Test Equipment Issues & How We Fix Them

Fix Loop Unlocked Error

A loop unlocked error is a common issue in RF signal generators and analyzers. It occurs when the phase-locked loop (PLL) fails to lock onto a frequency, leading to inaccurate results or total equipment failure. Causes can include:

• Faulty reference signals
• Damaged components
• Incorrect frequency settings

At Restore RF, we diagnose the root cause and repair or replace faulty PLL circuits, ensuring your test equipment locks frequencies properly.

Fix Loop Unlevel Error

The loop unlevel error typically indicates an issue with power leveling. This can result from:

• Defective attenuators
• A failing amplifier
• A miscalibrated power detector

Our skilled technicians perform precise troubleshooting and recalibration, restoring accurate power output levels to your RF test equipment.

Fix Frac-N Error

A Frac-N (Fractional-N) error occurs in synthesizers when the fractional-N phase-locked loop malfunctions, leading to unstable frequencies or poor phase noise performance. Common reasons include:

• PLL loop instability
• Damaged loop filter components
• Firmware or calibration issues

We specialize in diagnosing and repairing Frac-N issues, ensuring your RF equipment maintains proper frequency generation.
