Remote mixer distances
Mixers require a certain LO drive power level; the output power of the 85309B LO/IF dis-
tribution unit and the RF loss of the cables will determine the maximum allowable cable
lengths. Maximum cable lengths can be calculated using the following equations:
Cable (source to 85309B) length (meters) = (P
OUT
source – P
IN
85309B)/(cable loss/
meter at frequency)
Cable (85309B to mixers) length (meters) = (P
OUT
85309B – P
IN
mixer)/(cable loss/meter
at frequency)
