Functional description
ENRLB48 is both a hardware and software equipment designed for real-time
recording of analog IF signals, IQ (1), or base band (1) of an
instantaneous pass-band up to 48 MHz. In option, Digital signals can also
be recorded and replayed with the ENRLB48 via a Digital 32bits bus up to
50MHz max clocking LVDS or FPDP I / II standard.
Acquired data are stored on Hard Discs of the equipment. They can be analysed
by a spectrogram for analog replay of full or part of the recorded signal,
on a programmable IF or on base band (1). They are also available for transfer
to other processing systems that are network-connected to the equipment
(Gigabits Ethernet network).
The ENRLB48 is composed of a 3U, 19’’ rack mount
PC including:
- High performance cPCI Pentium M CPU card equipped with a PMC SCSI Ultra
320 card. Different digital control interfaces (PS2, USB, VGA, COM, Ethernet,
…) are also enable.
- A Wide Band Acquisition Replay cPCI card (ARLB) developed by i2e. Analog
interfaces and digital processing of acquired or replayed signals are included.
- A 438 Go storage unit (extensible) composed by 6 extractable Hard Disks.
The system can be remote controlled by local network linked or wireless
(WIFI).
By adding a TFT17'' screen with keyboard and a 2 buttons + scrolling mouse,
a stand-alone working can be available.
Inputs-Outputs at the Front :
- 10 MHz Reference (I/O), I/BB (I/O), Q/BB (I/O), IF in (I), IF out (O)
