PNA-X Series test set and power configuration options (continued)
4-port standard test set, power range and an internal second
source (Option 400)
The standard 4-port test set comes with 12 front-panel access
loops and a built-in second source. The loops pro- vide access
to the signal path between (a) the source output and the refer-
ence receiver, (b) the source output and directional coupler
thru arm and (c) the coupled arm of the directional coupler and
the port receiver. The inter- nal second source provides an
additional signal (fixed or swept) for two-tone third-order-inter-
cept (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. With two sources, source 1 is accessible
through test ports 1 and 2, and source 2 is accessible through
test ports 3 and 4. The standard test set also includes a solid-
state internal RF transfer switch in the R1 reference-receiver
path. Option 080 is recommended.
High-power configurable and extended power range
(N524xAS Option H85/485)
With extended power range and bias-tees (Option 419), the
internal bias-tees limit the maximum test port input power to
+30 dBm. The N524xAS Option H85/485 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 Option H85/485 adds
internal attenuators and cables. The N524xAS Option H85/485
and Option 419 can not be ordered together. Option H85/485
is not available for the N5247A. When ordering, select
N524xAS then add items N524xAS-H85, N524xAS-485 and
N524xA-400.

Extended power range and bias-tees (Option 419)
Adds to the standard test set one 65 dB for N5241/52A, 60 dB for
N5244/45A, and 50 dB for N5247A source attenuator (settable in
5 dB increments for N5241/42A and 10 dB increments for
N5244/45/47A), one 35 dB receiver attenuator (settable in 5 dB
increments) for N5241/42/44/45A and 50 dB receiver attenuator
(settable in 10 dB increments) for N5247A, and one bias-tee to
each test port. Option 419 requires Option 400.
Add an internal combiner and mechanical switches to 4-port
analyzer (Option 423)
Available with 4-port model only, this option adds a combiner and
mechanical switches. The mechanical switches provide increased
flexibility by having rear panel access (front panel access for the
N5247A Source 1 and 2 Out 1) to signal paths for advanced appli-
cations. Requires Options 400, 419 and 080.
