1.0 DESCRIPTION
The CamPac2 is a small lightweight HD/SD
COFDM microwave transmitter intended for
wireless camera applications including sports
coverage and electronic news gathering
(ENG). Its stylish, rugged machined housing
provides durability and excellent thermal
characteristics for operation in the harshest of
conditions. The transmitter can be mounted on
video cameras using integrated battery adapter
plates. Anton Bauer style plates are standard,
though IDX/Sony “V" clip may also be used.
The CamPac2 transmitter includes an
integrated MPEG2 encoder and variable
bandwidth COFDM modulator. This next
generation, high quality MPEG2 encoder can
be configured for HD and SD operation -or-
for SD operation only, while both versions
have an ultra-low latency mode for sports
coverage.
The encoder has the ability to be upgraded to
MPEG4/H.264. The variable bandwidth
modulator offers very high data rates through
efficient use of available bandwidth. Data
rates in the 20 to 50 Mbps rate can be
achieved in the robust QPSK, 16-QAM or 64-
QAM formats.
While the CP2 can be configured to utilize
COFDM bandwidths from 5-16MHz, the
6/7/8 MHz bandwidth modes are DVB-T
compliant to ensure compatibility with any
DVB-T standard system.
The CamPac2 accepts HD/SD SDI, ASI,
Analog Component and Composite video
input formats. The dual audio inputs can be
configured for mic or line input.
CamPac2 will also accept SDI Embedded
audio. The audio gains are easily set using the
programmable gain and the digital VU meters
displayed on the color TFT display. The
control panel uses a unique rotary dial that
senses the position of the user’s finger when
pressure is applied and rotated around the
disk. By dialing around the wheel and using
the (Esc) ▲and (Ent) ▼buttons, you can
navigate through the menu system.
The CP2 can be controlled remotely via RS
232/RS485 using a PDA or PC, and the
control panel may be removed and remoted up
to 100 feet away with an optional extender.
An N-type RF connector allows the CamPac2
to be used for applications where connection
to a remote antenna is required. For wireless
camera applications, an Omni-directional
antenna attaches directly to the RF output
connector, ensuring maximum EIRP
(Effective Isotropic Radiated Power).
The CP2 unit consists of a Base and a Power
Amplifier Module (PAM). The first
generation CP2 used an “IF” style interface
between the Base and PAM. The second
generation CP2 uses an “IQ” style interface.
Note: Earlier CamPac2 “IF” based units do
not support swapping PAM’s. “IQ”
based units do support interchangeable
PAM’s.
The RF function of the unit is determined by
the upconverter and amplifier installed in the
PAM. The unit is programmed with operating
frequencies and frequency ranges per
customer specification, allowing users to
customize their RF selections. The currently
available operating bands are (check with
Nucomm for availability of other bands and
PAM’s):
2GHz PAM: 1.990 - 2.700 GHz
7GHz PAM: 5.725 - 5.850 GHz
6.425 - 6.525 GHz
6.875 - 7.125 GHz
