WEIVER captures and playsback RF signals with center frequencies between 100KHz ~ 2.7GHz
RF signal and stores the le in its internal SSD or optional external SSD.
The major components in the WEIVER system include WEIVER Board (ADC, DAC and
Upconverter), Downconverter, and RF Attenuator. The system is powered by an industrial-
grade Windows Embedded 7. The RF Downconverter is capable of covering 100KHz to 2.7GHz
RF Signals and downconverts to 150MHz IF. The WEIVER Board consists of the ADC, DAC and
Upconverter. The RF Attenuator adjusts the power of the signal. The saved data les are in
16 Bit I, Q are the bandwidth around the center frequency of 8M, 24M, 48M and 56M Max.
Depending on the captured bandwidth, the SSD is capable of writing 40MB/s for a bandwidth
of 8M and 120MB/s for 24M, 240MB/s for 48M.
The WEIVER is capable of capturing all terrestrial RF signals including following signals [ DRM
/ FM / AM / DVB-T/T2 / DVB-S/S2 / DVB-C/C2 / DAB / DAB+ / ATSC / ATSC-MDTV / NTSC /
CMMB / QAM-B / ATV / ISDB-T / DTMB / T-DMB CDMA / CAL / UMTS / Wi / WiMax / PMR /
GPS / Galileo / Glonass / Bluetooth / LTE ]. WEIVER is equipped with Gigabit LAN ports. For the
captured RF signals the built-in GPS module provides pinpoint locative context every 1 second.
For precise location, the external active antenna is recommended. The GPS information is
stored in the NMEA protocol with the GPRMC information stored in a log le.
The Trigger function can be activated and deactivated. WEIVER
can get the capture started or stopped after receiving trigger
signals. The trigger signals from outside is a positive or negative
edge of TTL or CMOS. When the primary internal SSD is not
full, the WEIVER’s eSATA interface supports for lightning-fast
320MB/s write and 520MB/s read speeds to an external SSD.
The WEIVER has 10MHz Reference Clock input port to enable
for external synchronization.
