Cs tube ADEV is related to S/N ratio which is dependent on beam flux (the formula is in any quantum physics textbook).To achieve higher beam currents high-perf tubes run the oven at a higher temp (which is why their lifetime is much shorter).
So yes the RF chain is the same. But the oven controller set point is different and the E/M may be configured differently to accommodate the higher signal levels. /tvb (iPhone4) On Oct 27, 2012, at 8:07 PM, Magnus Danielson <[email protected]> wrote: > On 10/28/2012 01:13 AM, Chuck Harris wrote: >> Two things come to mind: >> >> 1) is this the high performance tube?
