FAST ACQUISITION
The maximum symbol rate for Fast Acquistion is 1028Ksps.
Fast Acquistion must be disable for rates greater than 1028Ksps.
Only supports QPSK and 8PSK in a NON-DVB MODE.
Does not support spectral inversion applications.
TM118 – Rev. 1.1
{50 – 90 MHz, 100 – 180 MHz, or 950 - 2050 MHz}
Allows the user to enter the Modulator IF Frequency in 1
Hz increments.
{NORMAL INVERTED}
Allows the user to invert the direction of rotation for PSK
Modulation. Normal meets the IESS Specification.
{QPSK, BPSK, OQPSK, 8PSK, 16QAM}
Allows the user to select the demodulation type.
{Intelsat 0.35, DVB 0.35, DVB 0.25, DVB 0.20}
Allows the user to set the spectral shape of Tx Data
Filter.
{±0 to 255 kHz}
Allows the user to set the acquisition range for the
demodulator
{0.0 – 6553.5 sec}
Allows the user to set the reacquisition delay time in
th
1/10
second increments.
{0 – 65535 Hz}
Allows the user to set the reacquisition sweep in 1 Hz
increments.
{Normal, Supressed}
Allows the user to indicate adjacent carrier as Normal or
Supressed (High Power). Unit will increase or decrease
post decimination gain appropriately.
{DISABLED, ENABLED}
Allows the user to disable or enable the Rx fast
acquisition capability.
