  • Annotazioni

  • The Marconi TF 2401 counter is a basic instrument into which plugs a frequency range unit and a function unit.

    The plug-in units at present available are a 50 MHz frequency range unit (TM 7557), a counter-timer function unit, and a 500 MHz converter unit (TM 7558).
    When used with these units the instrument performs the following basic measurements: Frequency, period, multiple periods, time interval, frequency ratio, and many other instructions.
    Features include an 8-digit read-out with memory.
