Introduction 1
1.1 General
1.1.1 Description
The Model 4430-V and the 4430-VN VME cards are high-performance tunable
BPSK/QPSK demodulator modules for the VMEbus. The demodulator features
a tunable input carrier frequency range of 6kHz to 6 MHz. A tunable modulator
is available for the Model 4430-V & VN for complete BPSK/QPSK system up-
link and loop-back capabilities on a single module.
The demodulator is a Costas Loop implementation with input circuitry that fea-
tures independently tunable high-pass and low-pass front-end filters (effectively
offering a band-pass filter). This input circuitry also offers 40 dB of AGC, thus
the demodulator can be connected directly to a receiver. The high level of pro-
gramming (tuning) offered by the Model 4430-V/VN makes it ideal for SGLS
and other multi-carrier applications.
All setup parameters for the Model 4430-V/VN such as carrier frequency, bit
rate, loop bandwidth and input filtering are programmable via the VMEbus.
Readback (status) of input signal presence and lock status are also available.
1.1.2 Description of the Specifications
➢
Standard Carrier Frequency 6 kHz to 6 MHz
➢
Supports Data Rates From 50 bps to 1.5 Mbps
➢
LBWs From .003 to 3% of Carrier Frequency
➢
Input Levels From -30dBm to +10dBm
➢
Optional On-Board BPSK/QPSK Modulator
➢
1 db (Eb/No) Synchronization Threshold
