MPM-551 Phase Meter  yOrder productionz
*End of production



The MPM-551 is a sensitive instrument for the accurate determination of phase relations from 0 to ±180° in the frequency range from 10Hz to over 2MHz.
It is specially suitable for use in the development and improvement of wideband amplifiers and networks where only the response measurements are not sufficient. In pulse work, phase adjustments can be made from 0 to ±180° by its use.


FEATURES

Maximum sensitivity is ±5° full scale, and by offsetting it is possible to obtain direct readings to 0.1° regardless of the phase angle.
DC voltage output proportional to the phase angle is available for operating a digital voltmeter when desired.
Ease of operation and maintenance are the keynotes in design.
