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 10.4” LCD touch screen display. The N5241A, N5242A, and
N5249A have 50 ohm, ruggedized 3.5 mm (m) test ports. The
N5244A and the N5245A have 50 ohm, ruggedized 2.4 mm (m)
test ports. The N5247A 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-port standard test set and power range
(Option 200)
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 transfer switch in the
R1 reference-receiver path.

High-power configurable and extended power
range (N524xAS Option H85/285)
With extended power range and bias-tees (Option 219), the
internal bias-tees limit the maximum test port input power to
+30 dBm. The N524xAS Option H85/285 removes the bias-tees
between the source attenuators and the test port couplers. This
extends the maximum port power that the analyzer can safely
handle to +43 dBm. Selecting OptionH85/285 adds internal at-
tenuators and cables. The N524xAS Option H85/285 and Option
219 can not be ordered together. Option H85/285 is not available
for the N5249A or the N5247A. When ordering, select N524xAS
then add items N524xAS-H85, N524xAS-285 and N524xA-200.
Extended power range and bias-tees (Option 219)
Adds to the standard test set one 65 dB for N5241/42/49A,
60 dB for N5244/45A, and 50 dB for N5247A source attenuator
(set table in 5 dB increments for N5241/42/49A and 10 dB incre-
ments for N5244/45/47A), one 35 dB receiver attenuator (settable
in 5 dB increments) for N5241/42/44/45/49A and 50 dB receiver
attenuator (settable in 10 dB increments) for N5247A, and one
bias-tee to each test port. Option 219 requires Option 200.
Add an internal second source, a combiner
and mechanical switches to 2-port analyzer
(Option 224)
Available with 2-port model only, this option adds an internal
second source, a combiner and mechanical switches. The inter-
nal second source provides an additional signal (fixed or swept)
for two-tone third-order-intercept (TOI) and intermodulation
testing of amplifiers, or it can be used as a fast swept-LO signal
for fixed-IF testing of mixers and converters. The mechanical
switches provide increased flexibility by having rear panel access
(front panel access for N5247A Source 1 and 2 Out 1) to signal
paths for advanced applications. Access to the second source
is available through two output connectors on the front panel.
Requires Options 200, 219 and 080.

1 The block diagrams shown above include hardware that must be ordered
as separate options, such as pulse generators (Option 025), pulse modu-
lators (Options 021 and 022), and IF access (Option 020). 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.
