The General Radio 1454-AH Decade Voltage Divider was introduced in Catalog P (1959) and remained available through Catalog S (1965).

Type 1454-AH is a four-stage voltage divider using the Kelvin–Varley divider circuit. The use of four special Type 510 resistance units achieve this. It features a constant 100 kΩ input resistance, with a maximum input voltage of 700 V at audio frequencies.

Applications for the 1454-AH include voltmeter calibration, measurements of gain and attenuation, and turns ratio of transformers.

Type 1454-AH is identical to the Type 1454-A except that all resistance values are increased by a factor of 10. Ungrounded or grounded operation is possible with a link at the input terminals.


  • Voltage Ratio: 0.0001 to 1.0000 in steps of 0.0001
  • Accuracy: ±0.04% of indicated ratio
  • Frequency Characteristics: frequency error is <0.1% at 2 kHz if the external capacitance placed across the output terminals is less than 50 pF
  • Input Resistance: 100 kΩ
  • Output Resistance: Varies with output setting
  • Maximum Input Voltage: 700 VRMS, limited to 350  VRMS for maximum accuracy
