• Notes

• 1 kHz - 60 MHz frequency counter Digipet 60,
  expandable to 130 MHz - 160 MHz, and 420 MHz - 460 MHz with optional add-on units.
  
  Runs on 100 VAC +/-10% 50-400Hz, or 12 VDC (10-14V) via screw terminal block on the rear of the unit.
  
  Resolution is 1 kHz or 1Hz, depending if the range is set to MHz or kHz respectively.

  Input sensitivity can be adjusted from 0.05 V, 0.5 V and 5 V RMS.

  Input impedance can be selected between 1 MΩ, 20 pF (1 kHz-60 MHz)
  or 50 Ω (300 kHz - 60 MHz).

  Maximum test input voltage is 150 V @ 1 MΩ impedance, and 5 V @ 50 Ω impedance.
