DSB/VSB
MODULATORS
|
| Modulators
are designed to convert a base band or A.V. (Audio Video) signal
into an RF signal. This allows the outputs from set-top boxes,
videos, DVD's, AM and FM tuners, CD players or cameras to be
integrated into any television system. By using Kingray and
Teleste's wide variety of agile modulators (able to adjust the RF
output frequencies via dip switches or software) a flexible
solution is available to suit each individual system. |
|
Double
Sideband (DSB) Modulator
|
| The
DSB modulator uses both upper and lower sidebands. This
means at least one, sometimes two channel spaces need to
be left so that the modulators dont interfere with each
other. While relatively cheap, it uses extra bandwidth. |
|
|
Vestigial
Sideband (VSB) Modulator
|
| The
VSB Modulator has the second sideband filtered out. This
allows you to place modulated channels adjacent to each
other. The second or lower sideband must be be attenuated
by 60 dB or more so it will not interfere with adjacent
channels. More expensive due to superior filtering but
makes more channels available. |

|
| |
| Kingray
have developed a new range of modulator products that can
be rack mounted or individually installed. The ideas have
come from your feedback. It is a product range that has
been designed to be as flexible as possible yet suit
numerous requirements including all future digital
products. These products are the KR (Kingray Racking)
Series and include a Passive Combiner, Powering Facility,
Wall Mount, 19” Subrack, Double Sideband Modulators and
a range of new generation Distribution Amplifiers.
Products currently being developed in the same series will
include V.S.B. Modulators, Demodulators and a Digital
Processing Headend. |

| MD100V
& MD100U |
|
The
MD100V (44-320 MHz) [230 mA @ 18V DC] and the MD100U
(470-860 MHz) [180 mA @ 18V DC] replace the three MD80
models. They are both double sideband modulators with
basic audio/video inputs and agile RF output. The outputs
are phase lock looped to provide stability and can be set
in 250 kHz steps. A test switch has been included to
assist with the initial setup. (There is an external 5.5
MHz input for optional future use with a demodulator as a
channel converter).
To
provide extra flexibility these units can have an output
of anywhere between 65-105 dB. This is achieved by the use
of a 20 dB gain control and a switch. The MD100's have
been build in the new die-cast housing for extra shielding
and can be rack mounted/powered, powered individually or
remote powered.
Two
power options are available:
| |
PSK18S
for single units.
PSK18KR for multiple units. |
|
(The
MD100V is currently undergoing further development to
increase the bandwidth to 44-470 MHz).
