Classification: CPC G  H | IPC G  H

Claim 0:
1. A signal analyzer, comprising:
an interface configured to receive a signal, in particular a radio frequency (RF) signal;
an analog-to-digital converter configured to digitize the received signal;
one or more processors configured to detect a trigger event in the digitized signal based on the digital signal having a certain preset signal shape and a display,
wherein the one or more processors are configured to store a segment of the digitized signal in a memory of the signal analyzer if the trigger event is detected in the digitized signal,
wherein the one or more processors are configured to analyze the stored segment of the digitized signal in order to detect signal anomalies including glitches in the stored segment of the digitized signal,
wherein the display is configured to display a list of stored segments of digitized signals, detected signal anomalies, and time stamps of the detected signal anomalies, and
wherein the one or more processors are further configured to detect the signal anomalies by a deviation of the digitized signal from a known signal spectrum and by a deviation of the digitized signal from a cyclical signal shape.
