Power at the analyzer inputs
Calculate the IF power levels at the receiver using the following equations:
P
REF
= P
RM
– conversion loss of mixers
1
+ conversion gain of 85309B – (L3 + L5)
P
TEST
= P
TM
– conversion loss of mixers
1
+ conversion gain of 85309B – (L4 + L6)
Where L = Cables losses as shown in Figure 11
Conversion gain of 85309B: ~23 dB (typical)
Caution: These values must not exceed the maximum input power level (0.1 dB
compression level) of the receiver (-27 dBm for Option H11 or -14 dBm for Option 014). Reduce the
power level of th e RF source if ne cessar y or ad d attenuator s prior to the m ixers or the an alyz er inputs .
Sensitivity
Now, determine the sensitivity required of the PNA network analyzer.
Sensitivity = P
REF
– DR – S/N
Where DR = Required dynamic range
S/N = Signal-to-noise ratio calculated previously
With this sensitivity number, select an analyzer from Table 1 that meets your
measurement needs.
1. Refer to Table 10 in the “Antenna measure-
ment components catalog” section on
page 58 for mixer conversion loss.
