Key Features and Benefits
High-Precision Differential Amplification for Weak Signals
The TEKTRONIX 5B12N delivers adjustable gain (1x to 100x) to amplify low-amplitude differential signals—down to microvolt (µV) levels—without introducing significant noise or distortion. This capability is critical for applications like measuring sensor outputs (e.g., strain gauge signals, thermocouple voltages) or analyzing power supply ripple in industrial control systems, where faint signals would otherwise be undetectable by a standard oscilloscope. For example, in a factory automation setup, the module can amplify a 10 µV differential signal from a pressure sensor to 1 mV (100x gain), allowing the oscilloscope to clearly display and analyze signal variations—helping technicians identify subtle changes that indicate sensor degradation or system inefficiencies.
Exceptional Common-Mode Noise Rejection
With a CMRR of ≥80 dB at DC to 1 kHz (and ≥60 dB at 10 MHz), the
TEKTRONIX 5B12N effectively rejects common-mode noise—electrical interference (e.g., from nearby motors, power cables, or industrial VFDs) that appears equally on both input terminals. This is a game-changer for industrial environments, where noise can corrupt signal measurements and lead to incorrect diagnoses. For instance, when testing a motor control circuit, the module will amplify the desired differential signal (e.g., PWM control signals) while suppressing common-mode noise from the motor’s power supply—ensuring the oscilloscope displays only the relevant signal, not interference. This noise rejection also reduces the need for external shielding or filtering, simplifying test setups and saving time.
Wide Bandwidth for Versatile Signal Analysis
The TEKTRONIX 5B12N offers a broad bandwidth (DC to 100 MHz at 1x gain, DC to 50 MHz at 100x gain), enabling it to handle both low-frequency signals (e.g., DC sensor outputs, slow analog control signals) and high-frequency signals (e.g., high-speed digital logic, RF interference). This versatility eliminates the need for multiple specialized amplifiers, making the module a cost-effective solution for diverse testing tasks. For example, in a power electronics lab, the module can analyze low-frequency battery voltage ripple (DC to 1 kHz) and high-frequency switching noise (up to 50 MHz) from an inverter—all with a single plug-in module. The flat frequency response across its bandwidth also ensures signal fidelity, so the amplified signal accurately represents the original waveform (no distortion or attenuation at critical frequencies).
Seamless Integration with Tektronix Oscilloscopes
Designed exclusively for Tektronix 5000-series and 7000-series oscilloscopes, the TEKTRONIX 5B12N features a plug-and-play design that connects directly to the oscilloscope’s chassis—no external power supplies or adapters required. The module is automatically recognized by the oscilloscope, which adjusts its settings (e.g., input range, bandwidth) to match the module’s capabilities—eliminating manual configuration errors. This integration also allows users to control the module’s gain settings directly from the oscilloscope’s front panel or software (e.g., TekScope PC Software), streamlining operation. For example, a technician can switch between 10x and 50x gain using the oscilloscope’s menu, without touching the module—ideal for dynamic testing scenarios where gain needs to be adjusted quickly.
Rugged Design for Industrial and Laboratory Use
Built to withstand the demands of both laboratory and industrial environments, the TEKTRONIX 5B12N features a durable metal housing, reinforced input terminals, and compliance with IEC 61010-1 safety standards (for protection against electric shock). Its operating temperature range (0°C to +50°C) suits controlled lab settings and slightly harsh industrial test areas (e.g., factory floors with moderate temperature fluctuations). The module also includes overvoltage protection (up to ±300 V input) and short-circuit protection, preventing damage from accidental input overloads—common in fast-paced testing environments. This ruggedness ensures the module maintains performance and reliability over years of heavy use, reducing replacement costs and downtime.
