As I send the parameter to the register, I take it that the 2595 would create a FMCW ,range from 12GHZ to 12.2GHZ,cycle 300us. When I use an oscilloscope to measure the wave, the blue line in Figure 2 shows that within the half cycle of frequency rise, within 50us, the period changes from 46.3*2ps to 41.3*2ps, which is equivalent to 10.8GHZ rising to 12.1GHZ, but the waveform drops sharply from 12.1GHZ to 10.8GHZ in the half cycle of frequency fall. As I expected the wave should be a Triangular wave, it actually became a sawtooth wave. Can anyone tell me the reasons and how to change the settings? Thanks !!!!
