Each module is a complete two-port VNA in a single PXIe slot, compatible with PXI Hybrid slots, and is designed to deliver S-parameter measurement quality in the modular form factor. Keysight identifies wireless manufacturing test, handset component test, aerospace and defense depot maintenance level testing, and aerospace and defense manufacturing test as the primary application areas for this family. The single-slot two-port architecture supports cost-of-test reduction by allowing simultaneous characterization of multiple devices, either two-port or multiport, within a single PXI chassis. ValueTronics International stocks and ships the M937xA family from our 20,000 sq ft secure warehouse at 1675 Cambridge Drive in Elgin, Illinois. Every unit moving through our facility is inspected and performance-verified by our technicians before shipment, and the same staff who handle the instrument will answer your questions about it. Unlike drop-shippers and pass-through brokers, we hold the inventory we sell and stand behind it with named, accessible support. ## Brand Heritage Keysight Technologies was formed in 2014 when Agilent Technologies spun off its electronic measurement business as a separate company. Agilent itself was spun off from Hewlett-Packard in 1999, which means the M937xA family traces its measurement heritage through the HP and Agilent test and measurement organizations. ## Compare Other Models in This Series The Keysight M937xA family is a six-model PXIe Vector Network Analyzer line that differs principally in upper frequency limit. All six models share the same single-slot PXIe form factor, the same full two-port S-parameter architecture, the same soft front panel, and the same driver and software ecosystem. The choice between models is fundamentally a question of how much frequency coverage the application requires. The six models span the M9370A at 300 kHz to 4 GHz, the M9371A to 6.5 GHz, the M9372A to 9 GHz, the M9373A to 14 GHz, the M9374A to 20 GHz, and the M9375A to 26.5 GHz. Keysight positions this family around the principle of paying for only the frequency range needed, and the comparison below is meant to support that selection. Each pre-owned M937xA model is listed as its own product page with condition-matched pricing and availability. Specifications referenced here come from the manufacturer datasheet covering the entire family; the per-page spec table reflects the specific model on that page. The M9375A is the top frequency tier in the family, covering 300 kHz to 26.5 GHz. At that upper range the datasheet specifies maximum leveled output power of -3 dBm from 20 to 24 GHz, a typical noise floor of -100 dBm above 24 GHz in a 10 Hz IF bandwidth, and temperature stability of ±0.020 dB/°C and ±0.60°/°C from 20 to 26.5 GHz. The primary differences across the family are upper frequency coverage and the specifications that depend on it. Maximum output port power, noise floor, dynamic range, and corrected error terms are all published as a function of frequency band, so a model with a higher upper limit inherits performance specifications across the additional bands while the lower-frequency behavior remains the same as the rest of the family. The accompanying comparison table summarizes the frequency range for each of the six models, along with the headline performance numbers as published in the datasheet. Use the table to confirm the model whose upper frequency limit matches the application before considering options, calibration kits, and accessories.
