The PNA-X is an integrated vector network analyzer featuring
a built-in S-parameter test set, one or two synthesized sources
used for device stimulus, a solid-state drive, USB interfaces,
and a 12.1” LCD touch screen display. The N5241B, N5242B, and
N5249B have 50 ohm, ruggedized 3.5 mm (m) test ports. The
N5244B and the N5245B have 50 ohm, ruggedized 2.4 mm (m)
test ports. The N5247B has 50 ohm, ruggedized 1.85 mm (m)
test ports. Included with each instrument is a mouse, keyboard
(U.S. style), and one day of on-site productivity assistance
(PS-S20-PNA).
A test set and power configuration option is mandatory, choose
one of the following:
2-ports, single source, with configurable test set
(Option 201)
The standard 2-port test set comes with six front-panel access
loops. The loops provide access to the signal path between (a)
the source output and the reference receiver, (b) the source
output and directional coupler thru arm and (c) the coupled arm
of the directional coupler and the port receiver. The standard test
set also includes a solid-state internal RF bypass switch in the R1
reference-receiver path.

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.
2-ports, single source, with configurable test set
and low frequency extension (Option 205)
Along with 2-port single source with the access loops with
Option 201, Option 205 adds bias tees and additional hardware
to extend the start frequency of the PNA-X down to 900 Hz.
The extended start frequency is available only for the following
measurement classes: standard, gain compression (amplifier and
converters), and for magnitude-only measurements using SMC
(scalar mixer/converter) or SMC+Phase. In the standard channel,
pulsed RF, true-mode stimulus, and source phase control are not
supported for measurements below 10 MHz. The block diagram
below shows how the low-frequency hardware is configured
for one test port; the other test ports are configured similarly.
For test port 1, the combiner and noise tuner (not shown) are
only available for use down to 10 MHz, and for test port 2, the
low-noise receiver (not shown) is only available for use down to
10 MHz.
