In industrial electronics, precision is everything. Whether you're validating a new PCB design or troubleshooting a control system, the accuracy of your test & measurement setup depends not just on your oscilloscope or multimeter, but on the probes and accessories you pair with it. Tektronix, a leading name in test & measurement, offers a wide range of high-performance probes and accessories designed to meet the demands of modern engineering environments.
Why probes matter: the unsung heroes of measurement accuracy
While oscilloscopes and analyzers get most of the attention, probes are the front line of any measurement system. They directly interface with your circuit, and their quality determines how faithfully signals are captured. Poor probe selection can introduce noise, distortion, or even damage sensitive components.
Tektronix probes are engineered to maintain signal integrity across a wide range of applications, from high-speed digital to power electronics. Their portfolio includes:
Passive voltage probes for general-purpose measurements
Tektronix passive probes deliver high bandwidth and low capacitive loading, making them ideal for general-purpose signal measurements. Models like the TPP1000 and TPP0502 offer up to 1 GHz bandwidth and are designed for seamless integration with Tektronix oscilloscopes.
Active probes for high-speed, low-voltage signals
Tektronix active probes, such as the TAP2500, TAP3500, and TAP4000, are designed for high-speed signal analysis with minimal loading. They feature ultra-low input capacitance, high bandwidth, and direct connectivity to TekVPI™ oscilloscopes, making them ideal for debugging and characterising fast digital designs.
Differential probes for measuring across floating signals or power rails
Tektronix high-voltage differential probes are designed for safe, accurate floating measurements in applications like motor drives, power converters, and switching power supplies. Models such as the THDP0100 and P5210A support differential voltages up to ±6000 V and bandwidths up to 200 MHz, with features like overrange indicators, switchable attenuation, and smart oscilloscope integration.
Current probes for non-intrusive current measurement in power systems
Tektronix TICP Series isolated current probes offer 1 GHz bandwidth and complete galvanic isolation, enabling accurate current measurements even in high common-mode voltage environments. With flexible probe tips, ultra-low noise, and compatibility with Tektronix 4, 5, and 6 Series MSOs, they’re ideal for everything from low-power mobile designs to high-current industrial systems.
Each probe type is designed to match specific bandwidth, impedance, and voltage requirements, ensuring accurate and repeatable results.
Key Tektronix accessories that enhance workflow & safety
Probe accessories are not mere add-ons; they are vital components of a complete measurement system. They address the practical, real-world challenges that arise during testing, enabling measurements that would otherwise be difficult, unsafe, or impossible.
Beyond probes, Tektronix offers a suite of accessories that improve usability, safety, and efficiency in the lab or field:
- Probe positioners and holders: Ideal for hands-free testing and reducing operator fatigue. They eliminate the need for crude, makeshift solutions like tape or clips, which can lead to unstable connections and inaccurate readings. Probe holders are also insulated, which helps prevent short-circuits in dense circuitry and provides an added layer of safety during probing.
- Adapter kits: Allow compatibility with various connector types and test points. Tektronix has developed several proprietary interfaces, such as TekVPI, to optimize communication and performance between the probe and the oscilloscope.
- Extension leads and tip kits: Provide flexibility in tight or complex setups. Tip kits provide specialized contact points, from fine-pitch probe tips for microelectronics to broad hook clips for larger components, ensuring that the user can make a secure and reliable connection regardless of the physical characteristics of the test point. Similarly, extension leads allow a probe to reach circuits that are physically located far from the oscilloscope or in a difficult-to-reach location within an enclosure.
- Protective cases and storage solutions: Help maintain calibration and extend product life. Given that many probes contain sensitive internal electronics, proper storage is not just about convenience; it is essential for maintaining the integrity and accuracy of the device, ensuring it remains within its calibrated specifications over time.
These accessories are especially valuable in environments where technicians need to perform repetitive testing, or where space constraints make traditional setups impractical.
