#32 - Complex Testing Methods

🔎 Complex Testing Methods (RF, HIPOT, Ground Bonding)

There are measurements that occur frequently in industry but go far beyond simple current or voltage measurements. In these cases, complex and sophisticated measurement logic must be implemented, which requires a high level of professional expertise and experience. In the upcoming posts, we will present three such testing methods.

Here is what we will cover:

📡 RF measurements
– The role and purpose of RF testing in end-of-line (EOL) validation
– Overview of signaling and non-signaling RF test methods
– Radiated and conducted measurement setups
– Measurement environment and equipment: antennas, chambers, VNA

⚡ HIPOT (high-voltage insulation testing)
– The purpose of HIPOT tests in verifying insulation and electrical safety limits
– Insulation resistance, AC/DC voltage withstand, and breakdown voltage measurements
– Typical voltage–time characteristics and protective functions of these tests
– Practical considerations: test instruments, verification functions, and grounding fault handling

🌍 Ground Bonding (protective earth continuity testing)
– The purpose of Ground Bonding tests in verifying protective earth continuity
– Typical measurements between the connector ground point and the device enclosure
– Comparison of two-wire and four-wire measurement methods
– Advantages of high-current testing: accuracy and current-carrying capability verification
