The Testec TT-HF-612RA is a 500MHz passive oscilloscope probe designed for high-frequency measurements in professional electronic testing environments. Part of the TT-HF series, this model features a readout attenuator (RA) for automatic scaling recognition on compatible oscilloscopes, streamlining workflow in high-speed digital and RF applications.
With 10:1 attenuation and 10 MΩ input impedance, the probe minimises circuit loading while maintaining signal integrity. Its low input capacitance (10 pF) ensures accurate capture of fast transient signals, critical for debugging embedded systems, power electronics, and communication protocols. The 1.3m shielded cable provides flexible positioning with minimal noise interference, while the CAT I 500Vrms rating ensures safe operation in standard laboratory conditions.
Unique to the 612RA variant is the integrated readout actuator, enabling automatic probe identification on oscilloscopes supporting TekVPI™-style interfaces. This eliminates manual scaling errors during multi-probe setups. The probe’s compensation range (10-20 pF) ensures compatibility with most modern oscilloscopes, and factory-adjusted HF compensation guarantees <0.7ns rise time performance out of the box.
Engineers requiring basic functionality without readout capabilities may consider the standard TT-HF-612 variant. However, the 612RA’s automated scaling and Mediator-compatible design make it ideal for mixed-signal environments where probe management efficiency is paramount.
