This is a complete list of the technical specifications for the N5244A and N5245A with the following options:
Option 029, adds hardware and firmware for high-accuracy noise figure measurements. It requires one of Option
224 or 423. See the block diagram.
Option 200, 2-port standard test set (includes six front-panel access loops) and power range. See the block
diagram.
Option 219, adds 2-port extended power range, source and receiver attenuators, and bias-tees (requires Option
200). See the block diagram.
Option 224, adds an internal second source, a combiner, and mechanical switches to the 2-port analyzer (requires
Option 200, 219, and 080). See the block diagram.
Option 400, 4-port standard test set (includes twelve front-panel access loops), power range, and an internal
second source (Option 080 recommended). See the block diagram.
Option 419, adds 4-port extended power range, source and receiver attenuators, and bias-tees (requires Option
400). See the block diagram.
Option 423, adds an internal combiner, and mechanical switches to the 4-port analyzer (requires Option 400, 419,
and 080). See the block diagram.
Notes
Specifications for the N5244AS and N5245AS Option H85, when configured in standard configuration, are the same
as those of closest N5244A and N5245A option configuration.
The Corrected System Performance with Cal Kits and Dynamic Accuracy Charts apply ONLY to N5244A/45A models
with serial numbers starting with MY5244/45, SG5244/45, and US5244/45, and above. This document provides
technical specifications for the 85056A calibration kit, and the N4693A 2-Port ECal module. Please download our
free Uncertainty Calculator from http://www.keysight.com/find/na_calculator to generate the curves for your
calibration kit and PNA setup.
For all tables in this data sheet, the specified performance at the exact frequency of a break is the degraded value of
the two specifications at that frequency.
Definitions
All specifications and characteristics apply over a 25 °C ±5 °C range (unless otherwise stated) and 90 minutes after
the instrument has been turned on.
Specification (spec.): Warranted performance. Specifications include guardbands to account for the expected
statistical performance distribution, measurement uncertainties, and changes in performance due to environmental
conditions.
Characteristic (char.): A performance parameter that the product is expected to meet before it leaves the factory, but
that is not verified in the field and is not covered by the product warranty. A characteristic includes the same
guardbands as a specification.
Typical (typ.): Expected performance of an average unit which does not include guardbands. It is not covered by the
product warranty.
Nominal (nom.): A general, descriptive term that does not imply a level of performance. It is not covered by the
product warranty.
Calibration: The process of measuring known standards to characterize a network analyzer's systematic (repeatable)
errors.
Corrected (residual): Indicates performance after error correction (calibration). It is determined by the quality of
calibration standards and how well "known" they are, plus system repeatability, stability, and noise.
6
Uncorrected (raw): Indicates instrument performance without error correction. The uncorrected performance affects
the stability of a calibration.
Standard: When referring to the analyzer, this includes no options unless noted otherwise.
7
Corrected System Performance
The specifications in this section apply for measurements made with the N5244A and N5245A
analyzer with the following conditions:
 10 Hz IF bandwidth
 No averaging applied to data
 Isolation calibration with an averaging factor of 8
 Source in filtered mode where applicable
System Dynamic Range and Receiver Dynamic Range
 System Dynamic Range is defined as the maximum leveled output power (spec) minus the noise floor (spec).
 Extended Dynamic Range at Direct Access Input is defined as the maximum leveled output power (spec) minus
the direct receiver access input noise floor (spec).
 Receiver Dynamic Range is defined as the test port compression at 0.1 dB (typical) minus the noise floor
(typical).
The effective dynamic range must take measurement uncertainties and interfering signals into
account.
Direct receiver access should only be used when the receiver input will never exceed its maximum
receiver input. When the analyzer is in segment sweep mode, it can have predefined frequency
segments which will output a higher power level when the extended dynamic range is required (i.e.
devices with high insertion loss), and reduced power when the maximum receiver input level will
occur (i.e. devices with low insertion loss). The extended range is only available in one-path
transmission measurements.
System dynamic range may typically be degraded at particular frequencies below 500 MHz due to
spurious receiver residuals.

Limited by 0.1 dB receiver compression. Applies to devices with bandwidth <400 MHz. For devices with higher
bandwidths, calculate the DUT output noise power as -174 dBm + 10*log10(B) + Gain (dB) + NF (dB), where B is the
bandwidth of the DUT in Hz, and use the Max Input Power specification.

Dynamic Accuracy
Table 29. Dynamic Accuracy - Specification
Standard receiver accuracy of the test port input power reading relative to the reference input power level. It is
verified with the following measurements:

Compression over frequency

IF linearity at a single frequency of 1.998765 GHz using a reference level of -20 dBm for an input power
range of 0 to -60 dBm. For value below -60 dBm, refer to “VNA Receiver Dynamic Accuracy Specifications
and Uncertainties”.
Applies to the N5244A and N5245A with the following serial numbers.
N5244A and N5244AS: MY5244/SG5244/US5244 and above
N5245A and N5245AS: MY5245/SG5245/US5245 and above
For the performance of older analyzers, refer to the VNA Uncertainty Calculator.

Aperture (MHz)
In general, the following formula can be used to determine the accuracy, in seconds, of specific group delay
measurement:
±Phase Accuracy (deg)/[360 × Aperture (Hz)]
Depending on the aperture and device length, the phase accuracy used is either incremental phase accuracy or
worst-case phase accuracy.
Group delay is computed by measuring the phase change within a specified frequency step (determined by the
frequency span and the number of points per sweep).

In Filtered Mode, the signal path goes through filters to minimize harmonics below 3.2 GHz. In Hi Power Mode, the
signal bypasses the filters to maximize output power.

Option 029 affects only port 1 and 2 coupler thru insertion loss. Refer to Options 219, 419, 224, 423 for the
coupler thru insertion loss on port 3 or port 4. Port 1 impedance tuner switch is in bypass position and port 2 noise
receiver switch is in normal position.
