The AD-1 is a professional quality agile
audio/video demodulator. The unit pro­vides audio and video outputs from any
analog input channel in the 54 to 88
and 108 to 806 MHz frequency range.
The AD-1 is ideal for signal monitoring
and signal conditioning (audio/video
processing and remodulation) applica­tions. Agile channel selection permits
on-the-fly channel changes.

The AD-1 takes a single NTSC channel
in the 54 to 88 and 108 to 806 MHz fre­quency range and demodulates the
audio and video information. Baseband
audio and video as well as 4.5 MHz
audio subcarrier and mulitplex audio
are provided as outputs. The AD-1 fea­tures phase locked loop synthesized
frequency control with a tuning incre­ment of 250 kHz. Channel selection is
accomplished with the use of simple to
use front panel accessible dip switches.
A Nyquist filter provides stable, accu­rate demodulation of the vestigial side­band signal. Additionally, this filter mini­mizes distortion and preserves the tim­ing of the signal. Delayed AGC circuitry
automatically compensates for input
signal variations. The AD-1 also utilizes
a quasi-synchronous video detector that
has low differential gain and minimal
phase distortion. A quadrature audio
detector delivers a very low distortion
audio output. The broadband multiplex
audio, 4.5 MHz audio subcarrier, or the
optional BTSC stereo (L/R) or SAP out­puts make the AD-1 ideal for any stereo
application.
