Thurlby Thandar TF930 - 3GHz Universal Frequency Counter

The TTI TF930 uses a high quality temperature compensated internal frequency reference (TCXO) which has a low aging rate and is stable to within ±1ppm over the full temperature range. Its short warm-up time allows accurate measurements to be made even under portable battery powered conditions.

An External Reference input is provided and changeover from the internal timebase is automatic when an external reference standard is connected.
