Showman 6000 is a natural development of the very successful
5000 series in service world wide.
The advanced Showman 6000 series, offers a fully agile demodulator
for television RF signals in the range 45.25 to 860.25 MHz PAL or
55.25 to 801.25 MHz NTSC. A high performance conversion process
guarantees measurement quality performance with a dynamic range
of facilities.
Designed for ease of operation with tuning by Channel, Frequency
or Program and a clear LCD with menu options to configure the unit
to the application.
Showman 6000, for quality demodulation to base band or IF, video
and audio. Enhanced facilities give control for IF or RF source,
Zero Carrier Pulse (ZCP), Serial Control, Audio Monitor and comprehensive
Alarm monitoring.
These and additional features set the Showman in a class apart.
A cost effective demodulator with performance for almost any area
of the world.

|
|
Channel
|
Up to 198 channels available
pre-programmed to 'country or application' channel table.
Channel table selection through 'Configuration' menu.
|
|
Frequency
|
Channel selection via direct keying of Vision carrier
frequency.
|
|
Program
|
Up to 99 channels may be stored and recalled as 'Program'
selected channels.
|
|
IF
|
IF input selected via 'Configuration' menu.
|
|
Audio
|
Selected Audio output from available input sources,
level adjustable via 'Configuration' menu.
|
|
Monitor
|
Monitor Audio select through headphone socket, level
adjustable under menu control.
|
|
|
Phase locked video IF stage providing synchronous demodulation
and active carrier regeneration. Resulting in ultra
linear demodulation, good intermodulation performance
and pulse response. IF output is available for distribution
or re-modulation and has adjustable output level controlled
through the 'Configuration' menu.
|
|
A quasi split sound processor stage suitable for all
FM standards is used to provide excellent audio quality.
All outputs are low impedance, electronically balanced.
Each pair has output level control adjustable via 'Audio'
menu. NICAM units offer option to default to FM or silence
and also IEC/EBU 958 Digital Audio Output. Sound intercarrier
output as standard.
|
|
Display and Configuration menu
|
|
2 x 20 character LCD with contrast control and auto
scroll provides clear display of Channel, Frequency
and RF Input level.
Through the 'Configuration' menu, the user has control
of; Channel table selection, AFC, Sound trap, IF or
RF input select, RS232 or RS485 serial control options,
ZCP and associated line and position for depth of modulation
measurements.
