Beat Frequency Oscillator
Type 1022
A sig nal generator cove ring the
range of 20-20,000 Hz and designed
especially for aco ustic and e·lectro ­
ac oustic measurements. Logarithmi c
sweep and automatic drive for
recording of frequency response
curves. Th e output signal can be
frequency modulated and controlled
by a compressor loop.
