SER-6000
SPECTRUM EFFICIENT RECEIVER
L-3’s new Spectrum Efficient Receiver, 6th generation (SER-6000) is a 3U
rack-mount dual-channel telemetry receiver that operates in P, L, S, C-IF and C-RF
bands and features a 7-inch dual-touch screen color display.
L-3 Telemetry & RF Products’ (L-3 T&RF) SER-6000 is a next-generation compact receiving
system that combines two high-performance telemetry receivers, DSP-based multi-mode
demodulator with programmed IF and video FIR filters, a programmable bit synchronizer
and frame synchronizer within a single 5.25-inch rack-mounted chassis.
L-3’s user-friendly SER-6000 touch screen interface allows easy installation, calibration,
configuration and monitoring of the product.
FEATURES
• Up to five bands installed in one receiver; C-Band RF/IF frequencies available
• Fully compatible with IRIG Tier-0, Tier-I
Use of U.S. DoD visual information does not imply or constitute DoD endorsement.
• Dual, independently tunable receivers with multiple first- and second-IF bandwidths, an
internal high-speed pre-D AM/AGC
• Pre-D Combiner with optimal Ratio and optimal select modes
• Excellent adjacent channel rejection using multiple SAW first-IF bandwidth filters along with
highly selectable FIR second IF filters
• Multiple, user-selected second IF FIR pre-programmed filters. Bandwidths from 50 kHz to 45
MHz tunable in 1 KHz increments are available for each channel.
• Multimode FM, PM, AM, BPSK, QPSK, OQPSK, SOQPSK demodulator
• Programmable I/O allows multiple analog or video outputs for each channel
• Built-in instrumentation, including RF spectrum display, constellation and eye diagram views
• Compatible with both conventional auto-tracking antenna systems and linear predictor
antenna tracking systems (common in phased-array antennas)
• Internal bit and frame synchronizers for each receiver channel (Bitsync only on combined
output)
• Two 70MHz tape playback inputs

TUNER
L-3’s SER-6000 contains dual-channel tuner section. The tuners are independently tunable, thus allowing for frequency or space diversity
combining. Available frequency ranges include P, UL, LL, S/E, C-IF and C-RF Bands. The tuner’s center frequency can be selected with a
resolution of 100 kHz either from the front panel or by remote control.
Envelope AGC is derived from a peak AM detector with five selectable time-constant settings and three modes of gain control (AGC/
manual/freeze). Eight pre-selectable SAW filters provide selectable analog filtering of the IF prior to digital conversions and demodulation,
improving adjacent channel and in-band rejection performance.

DIGITAL MULTI-MODE DEMODULATOR
Dual multi-mode demodulators employ the latest application-specific technology in processing the 70 MHz IF signal. Each demodulator
provides FM, PM, BPSK, QPSK, OQPSK and SOQPSK operation supporting data rates as high as 30 Mbps. The flexible nature of the
demodulators and the associated IF and video filtering allow them to be used for a wide range of applications and easily reconfigured as
applications change. The internal pre-programmed second-IF FIR filters provide bandwidths from 50 kHz to 45 MHz. The Digital IF filters
are tunable in 1 KHz increments. All standard IRIG filters are available.
Multiple analog video outputs are available for channel via the programmable output configuration. Programmed video FIR filters provide
maximally flat group delay filters. Video filters are provided with the -3 dB bandwidths from 150 kHz to 30 MHz in 1 KHz increments. The
SER-6000 provides user-controllable video output levels in 1 dB steps. The user can also control the video coupling (AC/DC) and video
polarity.
