1. A This depends on your radar system For traffic speed displays a typical range will be around 3 to 5 meters Q Why do I get different output amplitudes at the same radar transceiver A For precision sensitivity tests K DT1 and also the unit under test UUT should be mechanically fixed You should also prevent objects nearby the direct link between K DT1 and the UUT Use distances gt 30cm between K DT1 and the UUT Use absorber material e g Ecosorb AN or Ecosorb LS from Emerson amp Cuming if the test setting is placed on a table or in a test chamber gt What is the expected battery life With a daily use of 50 seconds Alkaline cells should last about 1 year Is battery loaded while K DT1 is connected on USB port No K DT1 is powered by the USB port during a host connection How can I measure frequency and RF power of my transceivers K DT1 is only a Doppler Simulator For power and frequency mesurements you may use the RFEbeam K TS1 system PFO FO User Manual Revision History Version Date Changes 1 0 15 Sept 2009 initial release 1 1 15 Oct 2009 corrected chapter Selecting Another Preset RFbeam does not assume any responsibility for use of any circuitry described no circuit patent licenses are implied and RFbeam reserves the right at any time without notice to change said circuitry and specifications 2009 RFbeam Microwave GmbH www rfbeam ch Page 9 92.
