INTRODUCTION
The DVE5000 series Digital Video Exciters are a combined HD / SD MPEG Encoder,
Modulator and integral serial HPA controller, all contained within a single ½ width 1U-rack
unit.
Output options include:
“70MHz”
52 - 88MHz
“L- Band”
950 – 1750MHz
“ASI”
270Mb/s to ISO / IEC 13818-2 188bytes
L-Band models include an L-band input for the combining of external communications
equipment or other DVE’s for MCPC applications.
A monitor output is also provided for connecting to an IRD or spectrum analyser. L-Band
monitoring is performed after “combining”.
L-Band output is tuneable from 950 to 1750MHz in 1 KHz steps, and the amplitude can be
varied over a 40dB range. The maximum output is +5dBm.
The DVE5000 provides, at L-Band, QPSK DVB-S modulation and optionally can provide
additional 8PSK and 16QAM modulation schemes.
DVBS-2 can also be provided optionally at QPSK / 8PSK / 16APSK / 32APSK.
An optional 70 MHz output is provided which can provide DVB-T / LMS-T* / DVB-S / DVBS-2
modulation schemes.
The 70MHz output is tuneable (dependant on symbol rate / bandwidth) from 52 MHz to
88MHz in 1 KHz steps. Amplitude can be controlled by up to 12dB’s dependant on
modulation scheme.
The 70MHz output is not available at the same time as the L-Band output; in L-band mode
the 70MHz connector becomes the ASI output.
The basic model provides PAL / NTSC analogue standard definition source encoding at
4:2:0 with 4 channels of analogue audio.
Options available can provide encoding at High Definition, 4:2:2, SDI video input with
embedded audio, eight channel AES / EBU digital audio inputs, Dolby E pass-thru’, BISS
conditional access, and a very low delay mode at <80mS (SD).
Similarly options are available to provide an ASI input for further multiplexing with other
exciter units or existing ASI streams.
Video encoding @ 4:2:2 can be up to 50MB/s (SD), 80MB/s (HD) when using internal
modulator and up to 100MB/s (HD) in ASI output mode.
This manual provides information on the complete range available; note that not all options
are fitted at time of manufacture, and may require a return to factory for future hardware up-
grades. Purchases of additional licence keys to enable functions not initially ordered may be
entered in the field. Firmware up-grades may be offered from time to time for the customer
to download into the DVE5000 to add additional features as they become available.
Full remote control can be made either by RS232/485 of the in built Web Browser.
Due to continual design improvements some features described may be modified or added
to.
Contact factory, customer support or agent if any query arises.
