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 time base is automatic when an external reference standard is connected.High ResolutionFor 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.Flexible Signal ConditioningInput A has configurable coupling (AC or DC), input impedance (1MW or 50W), attenuation (1:1 or 5:1), threshold (fully variable) and active edge, and can be used for frequencies in the range 0.001Hz to >125MHz. Input B is a nominal 50W input for frequencies in the range 80MHz to > 3GHz.Input C (TF960 only) uses a standard N connector and has a nominal 50W input for frequencies in the range 1.8GHz to > 6GHz.Multiple Measurement FunctionsThe TF930 and TF960 can measure frequency, period, pulse width, duty cycle and frequency ratio, as well as event counting (totalise).Remote Cont
