K5-501 & K5-503 modules (pre-rad) @ System Test


Setup

Strobe Delay Scan
The Strobe Delay Scan give "good" curves. No sign of what we see on the test box.
Three Point Gain (untrimmed)
The gain and noise versus channel number is flat. The mean input noise value for K5-501 is ~1540 e- and for K5-503 is ~1620 e-.
Trimming
The trimming gives 9 channels masked for K5-501. Many of the chips are trimmed at Trim Range 2.

The trimming gives 2 channels masked for K5-503. All chips are trimmed in Trim Range 0. There is one channel (260) not connected to the detectors (cut trace at fanin) and 2 noisy channels (385 & 386) that appeared after bonding. These last 2 are the masked ones.


Response Curve (trimmed)
The gain and noise versus channel number is flat. The mean input noise value for K5-501 is ~1575 e- and for K5-503 is ~1600 e-.
Noise Occupancy Scan
The Noise Occupancy @ 1fC is 3.35E-5 for K5-501. The Noise Occupancy @ 1fC is 4.34E-5 for K5-503.
Timewalk
In both modules the Timewalk is around 12 ns.
