What is the difference between the pulse and the FMCW (Frequency Modulated continuous Wave) measurement?

FAQ - RLS

1. Is it possible to set the 4…20mA output range, and how?
2. What is the shortest measuring interval?
3. What is the OTT RLS?
4. Q: What is the difference between the pulse and the FMCW (Frequency Modulated continuous Wave) measurement? A: • FMCW - constant signal – requires more power. • Pulse - short reoccurring impulses – less power consumption.
