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.
| Form factor | Flagship product | Best for |
|---|---|---|
| PXIe Chassis | M9019A · M9018B · M9010A | General-purpose ATE, semi parametric, RF |
| AXIe Chassis | M9505A · M9514A | High-power, high-bandwidth modules |
| PXIe Oscilloscopes | M9241A / M9242A / M9243A | Rack-mounted scope, benchtop performance |
| AXIe AWG | M8199A / M8199B | 200+ Gbaud high-speed digital / optical |
| PXIe VNA | P937xB Streamline / M937xA | Modular RF / microwave network analysis |
| PXIe Modular DC Power | N6700 + N673x modules | Multi-output ATE power |
| PXIe Vector Transceiver | M9421A VXT | 5G/6G, WLAN, IoT gen+analysis |
| BERT / SerDes | M8131A · M8045A | PCIe Gen6, DDR6, 800G PHY |
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 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 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.

Techmaster supplies the full Keysight software stack — OpenTAP, PathWave Test Automation, BenchVue, X-Series measurement applications — and integrates with existing LabVIEW, TestStand, or Python frameworks. Each system includes installation, software commissioning, operator training, plus ongoing ISO/IEC 17025 calibration.
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).
Yes. Primary PXIe chassis hosts the controller; AXIe daisy-chains via MXI-Express or PCIe extension.
Modular is 40–60% cheaper per channel above ~8 channels of digitizing, ~12 channels of power, or any multi-port RF.
Embedded Windows controllers (M9037A, M9038A) or remote PCIe (M9023A, MXI-Express) to external workstation. Linux supported via standard Keysight IVI/PXIe drivers.
Yes via Keysight Premium Used — chassis and modules with factory calibration and warranty.
