In addition to frequency measurement the TF830 offers period measurement, frequency ratio, pulse width measurement and event counting. Pulse width measurements can be made from rising to falling edge or vice versa.
The TF830 uses the reciprocal frequency counting technique to achieve high resolution at all frequencies. Reciprocal counting involves synchronised multiple period measurements followed by computation of the reciprocal value. This results in high resolution measurements regardless of the signal frequency and eliminates the +/-1 input cycle errors of a conventional frequency counter. The system yields at least 7 digits of resolution per second of measurement time and can measure low frequencies to a resolution of 0.001 mHz. To ensure maximum flexibility the TF830 can operate from disposable batteries, rechargeable batteries or AC line. Low power circuitry is combined with an LCD display to give up to 200 hours of operation from alkaline batteries.
The TF830 is available with the option of an addressable RS-232 interface. This can be used as a normal RS-232 interface or as part of a multi-instrument setup under the TTi ARC system. All front panel functions can be remotely controlled and measurements can be read back to the controller. This makes it suitable for use in a wide variety of automatic measurement systems.
