APSK R2 / R1 (Digital Demod)
Default: 32APSK, code rate 3/4, R2/R1 2.84 (See Digital Demod Standard Setups/Presets Table for additional default values.)
determines the Ring 2 to Ring 1 ratio for 16-APSK w/DVB and 32-APSK w/DVB digital format measurements.
The ring ratio is the ratio of the magnitude of symbol states on a ring (R2) to the magnitude of symbol states on the inner ring (R1). R2 / R1 is a valid parameter for both 16-APSK w/DVB and 32-APSK w/DVB format measurements.
The default ring ratios for 16-APSK w/DVB and 32-APSK are listed in the Digital Demod Standard Setups/Presets Table.
