Method for measuring locking time and frequency error in RF receiver |
摘要 |
A method is provided for measuring the locking time of an RF receiver. The method comprises inputting to the RF receiver an input sine wave with a certain frequency difference relative to the system operation frequency. An oscilloscope is used to capture the analog I and Q output signal of the receiver. The locking time is determined from the waveform imaged on the screen of the oscilloscope. Using the method allows measuring locking time accurately and in a short amount of time.
