The following specifications apply to the Configure Chirp (N Ch) VI when configuring a linear chirp signal.
|Start frequency range||0 to PDM rate/2|
|Stop frequency range||0 to PDM rate/2|
|Pre-chirp duration range||0 to 232 − 1 PDM samples, or approximately 23 minutes at PDM rate of 3.072 MHz|
|Chirp duration range||0 to 232 − 1 − Pre-chirp duration samples|
The linear chirp rate range, in seconds, is defined by the following equation:
Refer to the following table for maximum chirp rates at different PDM rates.
|Maximum Linear Chirp Rate||PDM Rate = 600 kHz||PDM Rate = 800 kHz||PDM Rate = 2.4 MHz||PDM Rate = 3.072 MHz||PDM Rate = 4.8 MHz|
|Range||±1.37 MHz/s||±2.44 MHz/s||±21.9 MHz/s||±35.9 MHz/s||±87.8 MHz/s|
|Minimum Time DC to PDM rate/2||7 ms||5 ms||2 ms||2 ms||1 ms|
