The AimTTi TF930 Universal Counter

The AimTTi TF930 Universal Counter uses an internal temperature-compensated TCXO of high quality. The lifespan is small and stable over ±1 ppm over the entire temperature range. An external reference can also be used. The measuring range runs from 0.001 Hz to 3 GHz.

At one second measuring time eight significant digits are available, nine in 10 s and ten digits in 100 s with accuracy of plus or minus two of the least significant digit. Input A is configurable on both AC and DC, impedance, input damping, threshold voltage and rising or falling edge.

The available measurement functions of this instrument are frequency, period time, pulse-width, duty-cycle and frequency ratio, in addition to event counting.
Via USB the instrument can be controlled from a PC. With the internal NiMH batteries the instrument can measure 24 hours (typ.).


  • Frequency range: 1 µHz to 3 GHz
  • Six measurement functions
  • High impedance measurement up to 125 MHz
  • Portable and bench use
