Modulation Meter Type AFM3 Section A. Introduction Accurate measurements on distorted sig nals are rendered easy by a switch that enables the positive and negative peak value to be measured separately. If in creased resolution is desired, an ext�ar nal indicator, such as a voltmeter, can be employed to extend the measuring range downwards. - Page 11 Section C. Accessories PLUG-IN CRYSTAL OSCILLATOR UNIT, CODE 900-252 COOE \I00.2S2 General The Plug-in Crystal Oscillator Unit, code 900-252, is preferably used within the frequency range 67 - 1 001 MHz to Fig. Cl. The Crystal Oscillator Unit, achieve low residual FM. It is supplied code 900-252.
