Comments: We saw that MB 2218 behaved in a strange way due to a trigger cable broken. It didn't delivered both real both calibration data. The floating timing trigger signal induced in the TDCs during the calibration corrupted the calibration and no data was delivered by the TDC. Therefore we changed the trigger cable.

test of MDC IV performed day: 29.03.2011

We have collected only calibration events, by setting: trigger type 9 on and pulser 10Hz.
Threshold has been set to 40 for all planes.
The following pictures are showing typical patterns (MBO vs. TDC) for MDC IV.

In this plot we only get a entry in case that TDC delivered 6 data words.

We can see some kind of pattern, which is repeated in all sectors, where some of the TDCs do not
deliver all 6 data words. This should be check if this is correct.

In addition we are missing some data words in sector 4 MBO 14.
