Option H11 – IF access
Option H11 is only available on the PNA network analyzers. Option H11 also requires

conversion stage. The external IF input allows 8.33 MHz IF signals from remote mixers
to be input directly to the PNA digitizer, bypassing the PNA’s RF conversion stage.
The test system becomes a distributed network analyzer with a tracking source and
a tuned receiver. This shifts the dynamic range curves and increases sensitivity by
approximately 20 dB.
OptionH11alsoprovidesaccesstotheRFandLOsignalsources(from1.7to20GHz)
of the PNA on the rear panel. This dual hybrid source eliminates the need for a separate
stand alone synthesizer when remote mixing is used. There is no power control over

be needed to achieve the power level required by the mixers. Table 2 shows the typi-
cal power levels available at the outputs. By removing the necessity of an external RF
source the test time is dramatically reduced. This is because the frequency stepping
speed is solely a function of the PNA where the settling time is in the uS range as
compared to mS range of most sources.

level requirements.
1. Test port power has to be at a high enough
level such that the Drop Cal does not occur. If
Drop Cal occurs, then the power out of the rear
panel RF connector will drop by about 15 dB.
