Capacitance Decade Box with Five Ranges

The REED Instruments R5406 is a digital test instrument that provides selectable capacitance values across five decade ranges. It is designed for technicians and engineers who need a precise, programmable capacitance source for circuit prototyping, calibration or educational demonstrations. The decade-box format allows quick switching between ranges without swapping discrete components.

Five Decade Ranges for Broad Simulation

The unit covers five decade steps, giving wide headroom to simulate many capacitor values encountered in filter tuning, timing circuits or sensor emulation. Resolution is limited to the decade increments provided, so applications requiring continuously variable capacitance or values outside the defined ranges will need a different instrument.

Highlights

  • 5 decade ranges cover wide capacitance values
  • Digital readout simplifies precise setting selection
  • Decade box design enables quick value switching
  • Compact test tool fits bench and field use

Questions about this item

Will the R5406 work with my older analog oscilloscope for calibration?

The R5406 is a digital decade box providing 5 decade ranges of capacitance, so it can supply precise values to any instrument that accepts external capacitance standards regardless of the instrument's age.

How do I verify the R5406 is delivering the correct capacitance after connecting it?

Select a decade range on the R5406, then measure the output terminals with a calibrated capacitance meter; the reading should match the selected decade value within the instrument's stated accuracy.
