Keysight (Agilent/HP) 86633B
Used for internal or external amplitude or frequency modulation (phase-locked FM). For internal modulation, the frequencies 400 Hz and 1 kHz are available. For amplitude modulation, the modulation depth is continuously adjustable from 0 to 100%. For frequency modulation, the adjustable deviation ranges from DC to 100 kHz (200 kHz at frequencies > 1300 MHz). Long-term stability in FM: same as in CW operation (at least 3 x 10E-8/day) External AM and FM modulation is possible in the frequency range from DC to 100 kHz. All functions of this plug-in can be programmed via the basic unit and the corresponding interface. MODULATION PLUG-IN
