# Agilent N5244A 43.5 GHz 2-Port and 4-Port PNA-X Network Analyzer (Pre-Owned) # Agilent N5244A 43.5 GHz 2-Port and 4-Port PNA-X Network Analyzer (Pre-Owned) ## Key Features At A Glance - Available in 2-port and 4-port configurations across the PNA-X series - Frequency coverage from 10 MHz to 50 GHz across the series (N5244A to 43.5 GHz; N5245A to 50.0 GHz) - 2.4 mm test port connectors at 50 ohm nominal impedance - 1 Hz frequency resolution with ±1 ppm frequency accuracy - System IF bandwidth range of 1 Hz to 15 MHz nominal - Optional high-accuracy noise figure measurement (Option 029; requires Option 224 or 423) - LAN (10/100BaseT), GPIB (IEEE-488), and USB 2.0 interfaces; LXI Class C compliant - Tiered options add extended power range, an internal second source, and a combiner 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. ## Brand Heritage 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. ## Compare Other Models in This Series 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.
