Add this 5" CRT SDU to any receiver with an
IF output; you specify the frequency (typically 10.7, 21.4, 45, or 70 MHz),
and see all signals in any span of spectrum from 0-10 MHz wide (slightly less on some
receivers). No sweep delay--30 sweeps per second allows real time
signal detection of the shortest signal bursts! 65 dB dynamic range, operates
from 120 VAC.
12VDC
available on special order. 120VAC/12VDC adaptation $35 at time of order.
Ideal for use with military and government receivers; ICOM R7000, 7100, 8500,
9000; AOR AR5000, AR3000A; and many more.
Specify your receiver's
IF at time of order. IF other than supplied 10.7 MHz is an additional
$200.00, due to the addition of the specific IF. A switch is provided
allowing the use of either frequency option.

APPLICATIONS
AVCOM's new SDM-42A Spectrum Display
Monitor is designed for use as a panoramic signal display for VHF scanners and
communication receivers such as the ICOM R-7000. The SDM-42A displays all
signals present in the receiver's IF on a 5" CRT so that the operator can
monitor signal activity. The operator can then quickly tune to signals as they
appear on the spectrum display. This greatly facilitates locating and tuning of
intermittent signals as well as surveilling a particular frequency band. The
SDM-42A Spectrum Display Monitor (with a scanner) can be used with AVCOM’s
PSA-65A Portable Spectrum Analyzer to create a powerful broad and narrow band
spectrum monitoring system.
The SDM-42A spectrum display can be used for other applications such as
monitoring satellite receiver IF's and demodulating single channel per carrier
satellite signals (with optional demodulator circuitry). It can also be used as
a general purpose spectrum analyzer covering specific frequency ranges.
