Understanding passive probes

Passive probes are the most common type of oscilloscope probe used in electronic test and measurement. In this presentation, you’ll learn why passive probes are favored for their rugged design, low cost, and ease of use across a wide range of applications. The concept of attenuation factors is explained, comparing 1X probes with 10X probes. Additional topics include automatic probe detection mechanisms, switchable probes, and the importance of probe compensation for accurate measurements.

What you’ll learn:

• The key differences between 1X and 10X passive probes, including their impact on bandwidth, input impedance, and circuit loading
• How oscilloscopes detect probe attenuation automatically and when manual configuration is required
• Why probe compensation is essential for accurate amplitude and pulse shape measurements, particularly with 10X probes
