Good Morning,

Today Hichem updated all the M301s in the array with a new image.

The T301(4P-Converter) now has calibrated total power detectors. One for 
RCP(XLP), and one for LCP(YLP). These TPDs are accurate within +/-1.5dB.

Also, we have added several average total power monitor points for each 
detector in the T301 and the T302(LSC-Converter). These monitor points 
average the last 20 seconds of TPD data, and present a running average. 
Data is taken once a second, and is calculated once a second. The 
averaging will give us better resolution in bands with RFI that comes 
and goes.

So, the first time all the TPDs in all the converter modules are 
operational and calibrated. Thanks to Hichem for all his hard work.


Eric
