  • Phase-Sensitive Voltmeter VP250.
    Intended mainly for deriving Nyquist characteristics of amplifiers in the range 20 Hz to 20 kHz.

    Two 6-inch centre-zero meters indicate respectively the in-phase and quadrature components of the output of the unit under test with reference to the phase of the input signal. Each of these meters is provided with a separate amplifier channel having input resistance greater than 50 MΩ; one of them has a 90° phase shifter. The meters themselves are wattmeters (to provide phase discrimination) of a new thermocouple type, to cover the wide frequency range. 

    Range of measurement is 15 mV to 15 V in seven ranges.
