Systems and methods for a signal processing device

A system, comprising:

• an electronic device including a first input operable to connect to a first signal line of a signal processing device, a second input operable to connect to a second signal line of the signal processing device, one or more processors, and a non-transitory memory including instructions that when executed cause the one or more processors of the electronic device to:
• record a first signal received at the first input during operation of the signal processing device;
• record a second signal received at the second input during operation of the signal processing device;
• detect whether a difference exists between an expected behavior of the second signal and an observed behavior of the second signal;
• and
• store, in response to a difference being detected, a recording of the observed behavior of the second signal and at least one of a recording of an observed behavior of the first signal and a recording of the expected behavior of the second signal in the non-transitory memory.

A method for detecting transient artifacts of an amplifier, comprising:

• connecting a first input of an electronic device to a first signal line of an amplification device;
• connecting a second input of the electronic device to a second signal line of the amplification device, the second signal line being downstream from the first signal line;
• establishing, based upon at least an observed behavior of a first signal on the first signal line and an expected amplifier gain between the first signal line and the second signal line, an expected behavior of a second signal on the second signal line;
• detecting an artifact based upon a difference between the expected behavior of the second signal and an observed behavior of the second signal;
• and
• storing, in the electronic device, a recording of the observed behavior of the second signal and at least one of a recording of the observed behavior of the first signal and a recording of the expected behavior of the second signal, based upon the detection of the artifact.
