TEKTRONIX 5A22N | Differential Amplifier Module

Product Overview

The TEKTRONIX 5A22N is a rugged, high-performance differential amplifier module engineered by TEKTRONIX—a global leader in test and measurement solutions—for integration with TEKTRONIX 5000-series and compatible oscilloscopes. Designed to amplify low-amplitude differential signals (e.g., from balanced circuits, power electronics, or sensor outputs) while rejecting common-mode noise, this module is a critical tool for test engineers in electronics manufacturing, aerospace, and research laboratories. Core features of the TEKTRONIX 5A22N include a wide bandwidth of 200 MHz (for capturing high-frequency signals), a gain range of 1× to 100× (adjustable via front-panel controls), and a high common-mode rejection ratio (CMRR) of 80 dB at DC (minimizing noise from ground loops or electromagnetic interference). With its robust mechanical design and compatibility with both bench-top and portable oscilloscope setups, the TEKTRONIX 5A22N ensures accurate signal amplification in diverse environments—from factory floor testing of power inverters to laboratory analysis of high-speed digital circuits. Additionally, the TEKTRONIX 5A22N supports differential input voltages up to ±500V, making it suitable for high-voltage applications like automotive battery management system (BMS) testing or industrial motor drive analysis.

Key Features and Benefits

High Bandwidth & Low Noise for Precise Signal Capture

The TEKTRONIX 5A22N’s 200 MHz bandwidth and fast 1.75 ns rise time enable it to accurately amplify high-frequency differential signals—critical for testing modern electronics like 5G transceivers, high-speed digital buses (e.g., PCIe 4.0), or power electronics switching at MHz frequencies. Its low noise floor (<50 μVrms) ensures that even weak signals (e.g., 100 μV sensor outputs from strain gauges or temperature transducers) are amplified without introducing excessive noise, preserving signal integrity for detailed analysis. For example, in aerospace applications, the module can amplify differential signals from aircraft engine vibration sensors (typically <500 μV) while rejecting common-mode noise from the engine’s electrical system—allowing engineers to detect subtle vibration anomalies that indicate potential component wear.

Exceptional CMRR & High-Voltage Tolerance

A standout advantage of the TEKTRONIX 5A22N is its high CMRR (80 dB at DC), which suppresses common-mode noise (e.g., ground loop voltage, EMI from nearby motors) that often corrupts differential signals in industrial or laboratory environments. This is particularly valuable for testing balanced circuits like audio equipment, industrial Ethernet (Profinet, Ethernet/IP), or power inverters—where common-mode noise can mask critical signal details (e.g., switching transients in inverter outputs). The module’s ability to handle ±500V differential and common-mode voltages expands its usability to high-voltage applications: for instance, testing automotive BMS systems (where battery cell voltages are measured differentially across 400V+ packs) or industrial motor drives (monitoring inverter output voltages to detect switching faults).

Versatile Compatibility & Rugged Design

The TEKTRONIX 5A22N is designed for seamless integration with TEKTRONIX’s legacy and modern oscilloscopes (e.g., 547, 555, 5850-series), leveraging the oscilloscope’s display and triggering capabilities for comprehensive signal analysis. An optional bench-top adapter allows the module to be used independently with non-TEKTRONIX oscilloscopes, increasing its versatility for mixed-brand test setups. Its rugged mechanical design (aluminum chassis, reinforced input connectors) withstands the rigors of field testing—for example, in automotive repair shops or aerospace maintenance facilities—while its wide operating temperature range (0°C to +55°C) ensures reliable performance in non-climate-controlled environments. The front-panel gain selectors and status LEDs (power, overload) also simplify operation, allowing technicians to quickly configure the module and identify issues like input overloads (preventing damage to the module or oscilloscope).
