OTM-3000
FREQUENCY AGILE - F.C.C. COMPATIBLE
TELEVISION MODULATOR
1) INTRODUCTION
The Olson Technology OTM-3000 is a frequency agile F.C.C. compatible television modulator that will pro-
vide high level output, on any channel from 55.25MHz, Ch. 2 through 445.25MHz, Ch. 61 (YY). All channels
are selectable in 1MHz increments by front panel DIP switches. F.C.C. offsets of +12KHz and +25KHz are
also selectable by front panel DIP switches.
The OTM-3000 uses SAW filtering for 60dB adjacent channel rejection. This unit also offers the unique
Olson Technology feature of >80dB out-of-band carrier to noise ratio which allows virtually unlimited numbers
of the OTM-3000 to be combined without the need for external band pass filters. The OTM-3000 is BTSC
stereo compatible.
2) CHANNEL SELECTION
Remove the front panel plate marked “Output Channel Select” to expose the channel select and offset select
