1455 Series Decade Voltage Divider


1455 Series Decade Voltage Divider

  • Linearity better than 20 ppm (5-dial model)
  • Input impedance: for 1455-A 10 kΩ & 1455-B, 1455-BH 100 kΩ
  • High-frequency model, down 3 dB at 7.5 MHz

The GR 1455 Kelvin-Varley Voltage Dividers provide accurately known voltage ratios from 0.00001 to 1.00000 for use in many common measurements:

1. Voltage gain or attenuation

2. Linearity of potentiometers and other controls

3. Frequency response of audio and rf networks

4. Transformer turns ratio

5. Voltmeter calibration

A resistive divider of the Kelvin-Varley type, the 1455 has precision resistors throughout (rather than in selected positions only) for over-all high accuracy. Linearity is as low as 0.02 ppm of input.
