Why would Sentry report discontinuities but not show any associated reason codes for the error?

Not every discontinuity (CC error) will cause a problem in an ES. For example, if a TS packet was dropped in the middle of a video slice, Sentry wouldn’t notice this as long as it can still detect the ‘start code’ progression in the video stream.

What fields / parameters contribute to making calculations for the QoE score?

Audio Buffer Overrun

Buffer timing violation causing buffer overrun and is greater than or equal to 100ms.

Audio Buffer Underrun

Buffer timing violation causing buffer underrun is equal to 0 seconds, meaning that the buffer is empty.

Setting up the Model 2400 SMU and 2182A Nanovoltmeter for Delta Mode.

A large source of error when making low resistance measurements (e.g. 1 ohm) is thermal EMFs in the circuit. A technique called Delta Mode reduces the thermal EMFs in the circuit. The delta mode method sources current in one polarity and takes a voltage measurement.
