 The
R-110 is a light weight, low power portable receiver with exceptional
sensitivity, very low noise figure and large dynamic range. The basic
receiver tunes over a frequency range of 1 kHz to 1 GHz and includes 26
bandwidths.
The
R-110 has proven itself in testing and surveillance applications though
out the world.
The
R-110B receiver is an enhanced version of the R-110 with several added
features. Covering the same frequency range of 1 kHz to 1 GHz, FM
demodulation, 33 bandwidths from 200 Hz to 200 MHz in a 1:2:5 sequence,
pulse stretch and slide back controls, and an accurate peak-reading DVM
to measure video signal levels and provide encoded data via the
IEEE-488.2 bus are included.
The
front panels have been engineered for clarity and ease of operation. A
full complement of analog controls, push-button switches, keypad, and
alphanumeric displays are provided. All of these features are easy to
learn and help the R-110 and R-110B user accomplish tasks with ease and
efficiency.
Both the R-110 and R-110B receivers accept plug-in modules to enhance
capabilities or to tailor the receiver for particular applications. The
Low Frequency Extender option uses one slot and extends tuning range to
100 Hz, and adds 50 Hz and 100 Hz IF filters.
The
receivers can be supplied in a portable configuration which includes
collapsible side handles and folding stand. Ears are available for rack
mounting.
The
receivers are compatible with various accessories, including the R-1180
Microwave Down converter, which extends the frequency range to 18 GHz,
and the R-110-40 Panoramic
