6-28 Maintenance
6.6.3 Acquisition System Tests
6.6.3.1 Critical Acquisition System Component Temperatures
In the service menu under AladdinAcqBoard there is a screen as shown below where the
temperatures of the critical components on the main card can be monitored. The MFE and
MFEEXT is the front end amplifier, the MAD is the ADC hybrid and the MAM is the
acquisition memory. (the MAM listed under channel 1 are for channel 1 & 2, the ones under
channel 2 are actually for channel 3 & 4) .The MTB is on the time base and trigger chip.
The Ambient is not measured. The MFE and MTB have traditional heatsinks mounted to
them, the MAD & MAM’s have a fan cooled heatsink mounted to them. A temperature
above 100°C is a cause for concern and should be corrected. Verify that the air inlet holes
or exhaust holes are not covered and that the fans are operating correctly.
