Leader LG 3236 Datasheet

AM/FM Synthesized Signal Generator

LG 3236

The LG 3236 Synthesized Signal Generator ranges from 100 kHz to 170 MHz and provides FM and AM modulation. A 5 ppm reference oscillator, ensures stable RF carrier frequency point. Electronic step attenuation, extends repeatability and service life for the RF output while eliminating switching noise. RF output level ranges from -20 dBµ to 126 dBµ in

0.1 dB steps. This combined with standard GPIB interface makes the unit a natural for automated production and inspection applications.

GPIB programming is expedited by using the 100 presets to store frequency, output level, modulation deviation and or depth, stereo pilot with level to internal memory and just recalling the presets as needed for the test routine. FM stereo separation is 55 dB or better and distortion is 0.05% or less. Simultaneous FM/AM modulation, factory option 70 adds another modulation oscillator and the simultaneous FM/AM modulation includes different modulation frequencies.
