The Agilent N5244A and N5245A are PNA-X network analyzers offered in two-port and four-port configurations. They characterize the magnitude and phase response of RF and microwave components by measuring reflection (Sii) and transmission (Sij) S-parameters across a swept frequency range, reporting corrected performance after error correction and uncorrected raw performance.
Beyond standard S-parameter measurement, these analyzers perform group delay measurements and, with the addition of pulse generators and pulse modulators, point-in-pulse and pulse-profile pulsed-RF measurements. Configured with Option 029, they add hardware and firmware for high-accuracy noise figure measurements. External IF inputs and the external test set driver also support measurement configurations that use remote mixers.
ValueTronics stocks and holds its own inventory in a 20,000 square foot secure warehouse at 1675 Cambridge Drive in Elgin, Illinois. Pre-owned units are inspected and functionally verified in-house by our technicians before they ship, while new units ship factory-sealed exactly as received from the manufacturer.
This instrument carries Agilent Technologies branding. Agilent was established in 1999 as a spinoff of Hewlett-Packard, and its electronic test-and-measurement business was renamed Keysight Technologies in 2014.
The PNA-X family on this page spans the N5244A and N5245A, each offered in two-port and four-port configurations. The series shares a common measurement architecture and option set, differing principally in maximum frequency coverage.
Across the series, the analyzers support corrected and uncorrected S-parameter measurement, group delay, and pulsed-RF measurement, and through the option structure can add extended power range, an internal second source and combiner, and high-accuracy noise figure measurement.
Each model below links to its own dedicated product page with pre-owned-matched pricing and availability. Select the model and configuration that fits your application, and the linked page reflects pricing for that specific pre-owned unit.
The two models differ in frequency coverage: the N5244A spans 10 MHz to 43.5 GHz, while the N5245A extends to 10 MHz to 50.0 GHz. Both are available as two-port or four-port instruments, and option suffixes (200/400, 219/419, 224/423) determine power range, second-source, and combiner capability.
Option 029 adds high-accuracy noise figure measurement on either model and requires Option 224 or 423. The comparison table below summarizes the frequency, port, and option differences across the configurations.
| Model | Frequency Range | Nominal (Preset) Power | Frequency Resolution |

| N5245A | 10 MHz to 50.0 GHz | -15 dBm | 1 Hz |
| N5244A | 10 MHz to 43.5 GHz | -5 dBm | 1 Hz |

Important: Direct receiver access should only be used when the receiver input will never exceed its maximum receiver input.
Important: 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.
Important: The Corrected System Performance (with cal kits) and Dynamic Accuracy charts apply ONLY to N5244A/N5245A (and N5244AS/N5245AS) units with serial number prefixes MY5244/45, SG5244/45, and US5244/45, and above.
Important: Corrected system performance is specified with the 85056A (2.4 mm) calibration kit and 85133F flexible test port cable set and a full 2-port calibration; these calibration accessories are required to achieve the corrected specifications and are ordered separately.
Important: Option dependencies: Option 029 requires Option 224 or Option 423; Option 219 requires Option 200; Option 224 requires Options 200, 219, and 080; Option 419 requires Option 400; Option 423 requires Options 400, 419, and 080.
Important: Specifications for Recall & Sweep Speed are not provided for the N522xA analyzers.
