TM110 – Rev. 1.3
{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.
{MIL-188-165A, INTELSAT 0.35, DVB 0.35, DVB 0.25}
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 – 900.0 sec}
Allows the user to set the reacquisition delay time in
th
1/10 second increments.
{0 – 32000 Hz}
Allows the user to set the reacquisition sweep in 1 Hz
increments.
{Normal, Suppressed}
Allows the user to indicate adjacent carrier as Normal or
Suppressed (High Power). Unit will increase or decrease
post discrimination gain appropriately.
{DISABLE, ENABLED}
Allows the user to disable or enable the RX Fast
Acqusition for low symbol rates.
{-30 to –90}
Sets a minimum carrier receive level when a carrier
drops below this level. IThe modem will sweep and try to
acquire a new signal. This prevents extremely small
carriers from falsely locking the modem.
{0.0 – 9.9 dB}
Allows user to select an EB/NO level that will trigger an
alarm when the received EB/NO is worse.
{Refer to Technical Specs for Data Rates}
Allows the user to set the Data Rate in bps steps via the
Front Panel Arrows or Keypad.
Allows the user to view the Symbol Rate.
