TF930.

TF930 is a high quality bench/portable universal frequency counter which offers period measurement, frequency ratio, pulse width and event counting. It uses an advanced reciprocal frequency counting technique to achieve high resolution at all frequencies. A DC coupled input enables VLF measurements to be made. The timebase uses a high quality TCXO crystal with a very low ageing rate. An external reference can also be used. The large 10 digit LCD has a full set of annunciators. Measurement times can be set between 0.3 seconds and 10 seconds. Pulse width measurements can be made from rising to falling or falling to rising edge with adjustable thresholds. A variable attenuator is incorporated the input impedance is switchable between 1MW and 50W. The instruments 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 4hrs and can be used for continuous AC operation.
