LG 3236 LG 3281 STEREO SIGNAL GENERATOR

The LG 3236(S1 version) Synthesized Standard Signal Generator  covers  a  wide  frequency  range  of  100  kHz  to 170 MHz and provides FM/AM modulation capabil-ity.    The  high-accuracy  crystal-controlled  reference  oscillator  ensures  highly  stable  RF  frequency  of  ±5  x  10-6 (5 ppm).The solid-state step attenuator is used for the RF out-put system to extend service life (because there is no mechanical contact), and is suited to frequent chang-es in output level such as in automatic production and inspection applications.For  modulation  functions,  the  LG  3236(S1  version)  is  equipped  with  a  high-quality  stereo  FM  modulator.  The  AM modulator supports up to 100 %. In addition, the LG 3236(S1  version)  is  equipped  with  a  simultaneous  AM/FM  modulation  function  (2  Audio  Frequency  systems)  and a DDS AF oscillator that covers a frequency range of 20 Hz to 20 kHz.FM stereo modulator and simultaneous FM/AM modu-lation capability is equipped.

FEATURES

Oscillation frequency is locked to a high-accura-cy reference oscillator to ensure accuracy of ±5 x 10-6 (5 ppm).■The  solid-state  step  attenuator  is  used  for  the  RF  output  system  to  extend  service  life  (be-cause  there  is  no  mechanical  contact),  and  is  suited  to  frequent  changes  in  output  level  such  as in automatic production and inspection appli-cations.■The  RF  frequency  covers  a  wide  range  of  100  kHz to 170 MHz.■The  output  level  can  be  set  in  the  range  of  -20  dBμ to 126 dBμ (0 dBμ = 1 μV, 50 Ω into open cir-cuit) in 0.1 dB steps.■Equipped  with  a  simultaneous  AM/FM  modula-tion function.■Two  systems  of  low-distortion,  fixed  oscillators  are  provided  as  AF  oscillators,  and  the  AM/FM  and the L and R of FM stereo can be set to dif-ferent frequencies.■The variable DDS oscillator is provided allowing arbitrary  AF  frequencies  to  be  specified  in  1-Hz  resolution.■The FM modulation supports up to 200 kHz and AM modulation up to 100 %.In addition, a wide bandwidth of external modu-lation  up  to  100  kHz  is  supported  for  both  FM  and AM.■FM stereo modulator is equipped.■Since  the  GPIB  interface  is  provided  as  stan-dard, this instrument can be incorporated into a GPIB measurement system.■The  numeric  keys  are  used  for  setting  the  fre-quency, output level, and modulation factor.■Up  to  100  preset  conditions  consisting  of  fre-quency,  output  level,  and  modulation  can  be  stored to internal memory.■All  front  panel  switches  (except  power  switch)  can  be  remotely  controlled  via  the  24-pin  con-nector on the rear panel.■An  SCA  input  connector  and  a  PILOT  output  connector  are  provided  for  connecting  instru-ments  such  as  an  external  FM  multiple  signal  generator.
