BPSK (Binary Phase Shift Keying) Channel 1 Example

Binary, Biphase, or Bipolar Phase Shift Keying (BPSK) is a means to rapidly select between two pre-programmed phases. The PMG-M-130 incorporates two separate 14 bit behavior registers to control the output phases identically effect both the I & Q outputs.  The logic state of the MODIN pin controls the selection of the Phase Set A (PS-A IBR-00-01) and Phase B (PS-B IBR-02-03) registers.  When MODIN=low, PS-A is selected and when MODIN=1, PS-B is selected.  The basic programming steps to incorporate BSPK are:

Note: If higher order PSK modulation is desired, the user should select the single tone mode and program PS-A using the 512K byte SRAM and the associated control pins on the Remote Control connector. Figure 1.0.0 below shows a typical operation of the BPSK mode.
