Revision as of 16:57, 21 December 2007

Tamuna and I test the DC preamp + postamp output using a pulse generator to create a 40 mV levelpulse that was 10 ns wide in order to simulate a pulse from the drift chamber proto-type.

This time we used Metalica but the results are not so different.

The bottom line appears to be that we get a x4 attenuation and not a net amplification deispite our efforts the change the configuration for the better. We also note that channels 1-11 of the postamp proto type attenuate by a factor of four but channels 12-16 have a signal independent of the input.


The voltage was changed
