PNA-X Series Test Set and Power Configuration Options
1
(Continued)
4-ports, dual sources, with extended power
range, combiner, and mechanical switches
(Option 422)
Along with two sources and the access loops and attenuators
of Option 417, Option 422 includes a combiner, mechanical
switches, and more access loops. The internal second source
provides an additional signal (fixed or swept) for two-tone
intermodulation testing of amplifiers, or for use as a local
oscillator for testing mixers and frequency converters. The
mechanical switches switch the combiner in and out as needed,
as well as enabling the additional access loops for advanced
configurations. The second source drives ports 3 and 4, and is
also available from port 1 when combined with source 1, or via
rear-panel access loops. The maximum power rating on the test
port couplers is +43 dBm (additional attenuators or isolators
are typically required to protect other components inside the
instrument). Option 422 is not available on the N5247B. To
independently control the frequency of the second internal
source, one of the following software applications is required:
S93080/029/082/083/084/86/087/089/090x/093/094B/A or
S94510/511A.

as separate options, such as pulse modulators (Options 021 and 022),
and IF access (Option 020), or is controlled by application software, as
is the case for the pulse generators. In addition, the combiner type and
attenuator values vary by model number. Refer to the product data sheet
for the correct block diagram for a specific model.
4-ports, dual sources, with extended power range
and bias-tees (Option 419)
This configuration comes with two sources, front-panel access
loops, and bias tees and source and receiver attenuators at
each port. The source attenuators are settable in 5 dB steps
up to 65 dB in N5241/42/49B, in 10 dB steps up to 60 dB
in N5244/45B, and in 10 dB steps up to 50 dB in N5247B.
The receiver attenuators are settable in 5 dB steps up to
35 dB in N5241/42/44/45/49B, and 10 dB steps up to 50 dB in
N5247B. The bias tees are connected directly to the test port
couplers, which limits the maximum power rating on the pair
to +30 dBm (additional attenuators or isolators are typically
required to protect other components inside the instrument).
To independently control the frequency of the second internal
source, one of the following software applications is required:
S93080/029/082/083/084/086/087/089/090x/093/094B/A or
S94510/511A.
