Option H11 – IF access
Option H11 is only available on the PNA network analyzers. Option H11 also requires
Options 014, 080, 081 and UNL. Option H11 provides direct access to the rst IF down-
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 the rear panel RF and LO signals. Power output ranges vary and external ampli-
ers may be needed to achieve the power level required by the mixers. Table 2 shows the
typical 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 com-
pared to mS range of most sources.

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.
