Noise figure options (continued)
Solid black series name indicates the feature is available on
that series, while gray series name with strikethrough indi-
cates the feature is not available on that series. For example;
PNA: Available on PNA Series
PNA: Not available on PNA Series
□ Fully-corrected noise figure measurements (Option 029)
PNA-X PNA PNA-L
This option adds a low-noise receiver and firmware to the PNA-X
1
for high-accuracy noise figure measurements of amplifiers, fre-
quency converters, and mixers, utilizing Agilent's unique source-
correction technique. Using an Agilent ECal module configured as
an impedance tuner for N5241/42A (3.5 mm N4691B-M0F recom-
mended; must be ordered or supplied separately), or a built-in
tuner for N5244/45/47A, the effects of imperfect system-source
match are removed, greatly improving the accuracy of the cold-
source technique. This approach 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 for N5241/42A, does not require the external
ECal module used as an impedance tuner. For calibration of the
noise receiver, Option 029 requires a power meter or a 346 series
noise source (346C or 346C-K01 recommended). For measure-
ments of mixers and converters, a power meter is always
required. The noise source and power meters are only used during
calibration of the analyzer, and must be ordered or supplied sepa-
rately. During the S-parameter portion of the noise calibration, a
separate ECal module or mechanical calibration kit is required
(also must be ordered or supplied separately). Option 029 also
allows noise figure measurements using the standard receivers
for high-gain (> 60 dB), narrowband devices that might otherwise
overload the low-noise receiver, or for noise figure measurements
up to 67 GHz on the N5247A
