• Notes

• True R.M.S Wideband Voltmeter

  The frequency response of this instrument permits the measurement of the true R.M.S. value of white noise in the range of 50 Hz to 10 MHz. 

  The voltage coverage is 0 to 300 V in nine switched ranges.

  The instrument consists of a high frequency Vacuo-junction preceded by a high gain-stabilised wide band amplifier. Readings are indicated on a 3½” meter.

  A typical application is the quick and accurate setting of noise levels in radar receivers
