The GW Instek GTP-100A-4 is a high-quality, switchable passive probe designed for professional oscilloscope measurements. Ideal for R&D labs, educational institutions, service centers, and production test environments, this probe provides the flexibility to measure a wide dynamic range of signals — from low-speed control signals to high-frequency clock waveforms.
Key Features
-
Dual Bandwidth Performance
-
10X Mode: 100 MHz bandwidth for high-frequency signal analysis.
-
1X Mode: 6 MHz bandwidth for low-level, sensitive measurements (e.g., ripple, noise, or power supply rails).
-
-
Switchable 1X / 10X Attenuation
Quickly toggle between attenuation ratios without changing probes, saving setup time and protecting your oscilloscope input from unexpected high voltages. -
High Input Impedance
Minimizes circuit loading, preserving signal integrity for accurate measurements. -
Robust 4-Meter Cable Length
The extended 4-meter cable provides flexibility to reach distant test points on large circuit boards or in crowded test racks — significantly longer than standard 1.2m–1.5m probes. -
Compact, Ergonomic Design
Lightweight and durable housing with a comfortable grip and slip-resistant surface for precise daily use.
