Key Features and Benefits
The TEKTRONIX 5A38 stands out for its high-frequency performance, versatility, and reliability—addressing critical challenges in ultra-fast signal measurement and analysis.
200 MHz Bandwidth for Ultra-Fast Signals
With a 200 MHz bandwidth, the TEKTRONIX 5A38 excels at capturing high-frequency waveforms that lower-bandwidth modules (e.g., 100 MHz) cannot resolve. This is critical for applications like aerospace radar signal testing, high-speed digital circuit validation (e.g., 100BASE-T Ethernet), and power electronics switching transient analysis (e.g., SiC/GaN inverter waveforms). Its <1.75 ns rise time ensures that even the fastest signal edges are reproduced accurately, providing engineers with a true representation of signal behavior to identify issues like overshoot or ringing.
Differential Input for Noise-Isolated Measurements
Unlike single-ended modules, the
TEKTRONIX 5A38 supports differential input, allowing measurement of voltage differences between two non-grounded points. This eliminates common-mode noise (e.g., power supply hum, electromagnetic interference from industrial equipment) that would corrupt single-ended measurements—essential for analyzing balanced circuits (e.g., differential amplifiers, twisted-pair communication lines) or signals in noisy industrial environments (e.g., factory floors with high-voltage machinery).
Low-Noise Amplification for Small-Signal Accuracy
Equipped with low-noise analog amplifiers, the TEKTRONIX 5A38 delivers exceptional signal-to-noise ratio (SNR) even for small-amplitude signals (down to 5 mV/div). This is critical for applications like sensor output testing (e.g., MEMS accelerometer signals) or low-voltage RF signal analysis, where background noise could obscure critical signal details. The module’s precise gain control (±1% accuracy) further ensures that measurements are consistent and repeatable.
Rugged Design for Industrial & Laboratory Use
Built to Tektronix’s rigorous industrial standards, the TEKTRONIX 5A38 withstands the demands of both laboratory and field testing. Its robust housing resists vibration (10–500 Hz, 2 G rms) and temperature fluctuations (0°C to +55°C), ensuring reliable performance in aerospace test facilities, manufacturing floors, or research labs. The ±400 V input voltage rating also provides protection against accidental overvoltage—common in industrial testing scenarios (e.g., measuring power supply outputs).
Seamless Integration with 5000-Series Oscilloscopes
As a native plug-in for Tektronix 5000-series oscilloscopes—a widely used platform in industrial and research settings—the TEKTRONIX 5A38 requires no complex calibration or third-party adapters. It leverages the oscilloscope’s existing time base and display system, allowing engineers to start measurements within minutes. Its compact form factor (fits standard 5000-series slots) also preserves bench space, eliminating the need for external signal conditioning hardware. Paired with our one-year warranty and technical support (including probe calibration guidance), this ensures long-term productivity and measurement confidence.
