IF input port selection (for 720 MHz or 1.2 GHz IF)
IF1 Nom , IF1 Alt
IF2 Nom, IF2 Alt
IF input port selection (for Wide Band)
IF1 Nom , IF1 Alt
Expected IF 520 to 920 MHz (nominal 720 MHz IF input) or 960 to 1600 MHz
(nominal 1.2 GHz IF input). expressed in Hz. Enter any value in float or real format.
Example: for 720 MHz, type: 72e+7 or 720000000. The programmed value is always
displayed in float format. Resolution step: 32-bit float format.
Carrier acquisition peak range (from the expected carrier frequency) and PLL tracking
range. Expressed in Hz. Enter any value from 10,000 to 2e6. Select a value that takes
into account the frequency offset in the worst operational conditions. (Doppler,
frequency uncertainties, etc.).
Carrier acquisition can be restarted at any moment by clicking on
 BPSK
BPSK demodulation.
 QPSK
QPSK demodulation.
 OQPSK
OQPSK or SQPSK or SOQPSK demodulation.
 UQPSK
UQPSK or AQPSK, AUQPSK, AUSQPSK demodulation
 8PSK
8PSK demodulation
 16QAM
16 QAM demodulation
 16APSK
16 APSK demodulation
 32 APSK
32 APSK demodulation
 64 APSK
64 APSK demodulation
For GMSK Select OQPSK + Matched filter = GMSK and then enter BTs value
For SOQPSK Select OQPSK + Matched filter = SOQPSK and then select the
dedicated filter
Enable the automatic switch function between 8PSK and OQPSK demodulation. This
function is only available with OQPSK and 8PSK modulation. In this mode, the
programmed symbol rate is constant.
It cannot be duplicated or distributed without expressed written consent.
