Aim-TTi TF930 Universal Counter

High measurement accuracy

The Aim-TTi TF930 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.

Flexible signal conditioning

Input 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 functions

The Aim-TTi TF930 can measure frequency, period, pulse width, duty cycle and frequency ratio, as well as event counting (totalise).

Remote control and read-back via USB

The Aim-TTi TF930 incporporate a USB interface which allows it to be remotely controlled using RS232 protocol via a computer’s USB port. The remote commands of their predecessor instrument, the TF830, are compatible with the command set.

Battery operation when needed

The Aim-TTi TF930 operate from internal rechargeable NiMH batteries which give typically 24 hours operating life. The universal AC charger supplied will recharge the batteries in less than 4 hours and can be used for continuous AC operation. The instruments can also be powered from a standard USB port.


Ten digit LCD

The high contrast display has ten 12.5mm (0.5”) high digits along with a comprehensive set of annunciators. These show input configuration and function, measurement time and status, external reference connection, low battery and the units of the measurement which may be Hz, kHz, MHz, ns, us, ms or s.
