High measurement accuracy
The TF930 and TF960 use 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.
High resolution
For frequency, period and frequency ratio functions the instrument uses a reciprocal counting technique to provide high resolution at all frequencies.
Eight significant digits of answer are produced in a 1 second measurement time, nine digits in 10s and ten digits in 100s with a granularity of less than 2 counts in the least significant digit.
