PNA Family Application Options
Measurement applications
Solid black series name indicates the feature is available
on that series, while gray series name with strikethrough indicates
the feature is not available on that series. For example;
PNA: Available on PNA Series
PNA: Not available on PNA Series
Spectrum analyzer (Option 090)
PNA-X PNA PNA-L
The spectrum analyzer (SA) option adds high-performance
microwave spectrum analysis to the PNA and PNA-X Series. With
fast stepped-FFT sweeps due to optimized data processing, the
SA option provides quick spurious searches over broad frequency
ranges. Option 090 enables spectrum measurements with the test
receiver at each test port, and a reference receiver (two reference
receivers for 2-port configuration) simultaneously. This multi-
channel SA used with the internal swept-signal generators allows
efficient spurious analysis of mixers and converters. The SA option
employs source power and receiver response calibration as well
as fixture de-embedding, providing in-fixture or on-wafer spec-
trum measurements with the highest level of accuracy. Requires
Option 080, Windows 7 OS, and DSP version 5. It is recommended
to use this option on instruments with receiver attenuators to
avoid receiver compression when measuring large signals.
Integrated true-mode stimulus application
(Option 460) PNA-X
Integrated true-mode stimulus application (iTMSA) provides
mis-match-corrected true-mode (true differential mode and true
common mode) stimulus and enables accurate balanced mea-
surements under real operating conditions. iTMSA also provides
balanced measurements with forward-only sweep, reverse-only
sweep, and frequency or power sweep with arbitrary phase and
amplitude off-sets. Requires one of Options 400, 401, 410, 417,
419 and 423.
1 When configuring N524xA as a multiport analyzer using Option 551 and a
multiport test set, the combiner feature of Option 224 or 423 is temporar-
ily disabled. When configured as a standalone analyzer, the combiner
feature is enabled. When ordering a test set, select an appropriate
interface kit. Refer to page 22 Multiport Measurements section for more
details.
2 Only N4690 Series ECal modules are supported for use as an impedance
tuner.

PNA PNA-L
N-port capabilities (Option 551)
PNA-X PNA PNA-L
Adds a multiport analyzer mode, which enables full N-port error
correction and measurement capabilities using an external test
set. Only standard measurement class is available in the multi-
port analyzer mode. Not available with PNA Options 200, 210,
400 and 410. For multiport analysis greater than 8 ports, it is
highly recommended to use PLTS software N1930B to manage
the large data format files that easily grow exponentially (12 port
S-parameter files have 144 S-parameter elements).

Noise figure options

Noise figure measurements using standard receiv-
ers (Option 028) PNA-X
This option adds firmware for high-accuracy noise figure mea-
surements of amplifiers, frequency converters, and mixers using
the analyzer's standard receivers, and utilizing Keysight's unique
source-correction technique. Using an Keysight ECal module
configured as an impedance tuner (N4691B/93A/94A-M0F
recommended; must be ordered or supplied separately
effects of imperfect system-source match are removed, greatly
improving the accuracy of the cold-source technique. This ap-
proach surpasses the accuracy provided by the Y-factor method
and other cold-source implementations. A scalar calibration
choice is also available that offers less accuracy but is faster and
does not require the external ECal module used as an impedance
tuner. For calibration, a power meter and separate ECal module
or mechanical calibration kit is required (must be ordered or
supplied separately). An external preamplifier and filter(s) is
required for devices with < 30 dB of excess noise (gain plus noise
figure in dB) up to 20 GHz, < 40 dB up to 50 GHz, or < 45 dB up to
67 GHz. Front panel jumpers provide a convenient spot for adding
a preamplifier and filter for low gain, low noise figure devices. Not
available with N522xA-200 and -400.
