- Module Name: Readout Card
- Module Number: SC2_MCE_S582_101
- Change From: Rev. B9 Change To: Rev. B10
- Date:Mar. 4, 2010, Requested by:MN/GPD
Problem Description
The pre-amp bandwidth is ~6MHz and this brings excess noise contribution in detector data.
Change Description
Reduce the pre-amp bandwidth to ~1.3MHz by moving the poles on the pre-amp chain. This involves changing the following 3 capacitors.
- Replace C74, C75 with 470pF (PN = 002205)
- Replace C76 with 68pf (PN=002206)
