Keysight Modular Instruments (PXI / AXIe) — Authorized Distributor in Vietnam
Techmaster Electronics distributes the full Keysight modular instrument portfolio in Vietnam — PXIe and AXIe chassis, modules, and reference architectures for automated test systems, semiconductor parametric labs, aerospace/defense ATE, 5G/6G research, and automotive ECU validation. When you need benchtop performance in a compact multi-channel rack form factor — or you are building a test system that integrates instruments, switching, and a controller into one cohesive platform — modular wins on density, synchronization, and cost-per-channel.
Why modular wins for ATE. A single PXIe chassis can host 18+ instrument modules behind one controller, sharing a low-jitter timing backplane and a high-bandwidth PCIe data fabric. That eliminates 80% of cabling, instrument-to-instrument trigger latency, and rack space of equivalent benchtop builds. Techmaster supplies chassis, modules, controllers, software stack (Keysight OpenTAP, PathWave Test Automation), and integration services.

PXIe Chassis — Backbone
Keysight’s M9019A is the workhorse: 18-slot 3U PXIe with 24 GB/s aggregate PCIe Gen3 bandwidth, low-noise power distribution, sub-nanosecond timing backplane. For smaller systems M9018B (18 slot Gen2) and M9010A (10 slot); for large multi-chassis builds MXI-Express daisy-chains scale to hundreds of slots behind a single controller. For Vietnamese semiconductor parametric labs (Intel, Amkor, Hana Micron) and automotive ECU test (FORVIA HELLA, Bosch, VinFast supply chain), this density makes inline parallel test economically viable.
AXIe — Higher Power and Bandwidth
AXIe exceeds PXIe’s per-slot power and size limits: high-speed AWGs, BERTs, multi-port VNAs. M9505A (5-slot) and M9514A (14-slot) chassis deliver higher per-slot power and larger module envelopes. Keysight’s flagship M8199B AWG (just launched, 448 Gb/s waveform generation at 128–256 GSa/s) is AXIe — the only practical packaging for that bandwidth in a system instrument.
Modular Oscilloscopes, AWG, VNA, Power, VXT, BERT
Modular oscilloscope family: M9241A (200 MHz), M9242A (500 MHz), M9243A (1 GHz), 2 GSa/s, 2 channels, PXIe 2-slot. AXIe AWG: M8199A/B for 800G/1.6T Ethernet, PCIe 6/7, DDR5/6, optical PAM4/PAM8. PXIe VNA: P9375B/P9377B/P9384B Streamline plus M937xA covering 9 kHz–53.5 GHz. Modular DC power: N6700 mainframe + N6731–N6755 modules (up to 4 outputs/slot, 5–600 V, 50 mA–50 A). M9421A VXT (60 MHz–6 GHz, 160 MHz BW) replaces signal generator + analyzer in one PXIe module — for IoT module production at Goertek and Universal Electronics. BERT: M8131A digital signal analyzer + M8045A pattern generator for PCIe Gen6, DDR5/6, 800G Ethernet, USB4. Anchor accounts: Marvell, Amazon HW, NVIDIA Vietnam design centers.

Each system includes installation, software commissioning, operator training, plus ongoing ISO/IEC 17025 calibration.
FAQ
PXI vs PXIe vs AXIe?
PXI is the original PCI-based modular standard. PXIe (PCI Express) is dominant for general ATE with up to 24 GB/s aggregate bandwidth per chassis. AXIe is a larger form factor for high-power, high-bandwidth modules (AWGs, BERTs, multi-port VNAs).
Can I mix PXIe and AXIe?
Yes. Primary PXIe chassis hosts the controller; AXIe daisy-chains via MXI-Express or PCIe extension.
Modular vs benchtop cost?
Modular is 40–60% cheaper per channel above ~8 channels of digitizing, ~12 channels of power, or any multi-port RF.
Controllers and OS?
Embedded Windows controllers (M9037A, M9038A) or remote PCIe (M9023A, MXI-Express) to external workstation. Linux supported via standard Keysight IVI/PXIe drivers.
Used / refurbished modular available?
Yes via Keysight Premium Used — chassis and modules with factory calibration and warranty.
