1454-AH
The General Radio 1454-AH Decade Voltage Divider was introduced in Catalog P (1959) and remained available through Catalog S (1965).
The Type 1454-AH is a four stage voltage divider using the Kelvin and Varley 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 700 V at audio frequencies. Applications for the 1454-AH include voltmeter calibration, measurements of gain and attenuation, and turns ratio of transformers. The 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.
