Conducted disturbance 1
EUT contains two approved modules: a low power radio operating in the 2.4-2.4835 GHZ Band “FCC ID WZK-PR-1002” + a 24 GHz Doppler
Radar “FCC ID WZK-PR-1001”. Both radios were active during the test.
December 11, 2017 and January 4, 2018
The Equipment Under Test (EUT) was an Invention Planet, LLC Smart Coach Radar Module. The coach radar module is a
pocket-sized general purpose speed doppler radar gun in the 24GHZ range that can be used for many uses including
traffic safety, radio controlled hobbies, motorsports, neighborhood safety, industrial safety, scientific research and much
more. You decide what to measure and when, using one of two modes – snapshot or repeating – to accurately monitor
the speeds of vehicles, radio controlled planes/cars, runners and any other moving object from 7-375 MPH (11-600 KPH).
The EUT also incorporates a low power radio operating in the 2400-2483.5 MHz ISM band.
During testing the Radar Module was transmitting continuously at both radios to simulate the worst scenario when the
radios are co-located in the final product
24GHz & 2.403-2.4835GHZ
EUT was running with 2.4GHZ + 24GHZ and both signals enabled at max power (One representative/worst case channel of each radio)

A preview measurement was generated with receiver in continuous scan or sweep mode while the EUT was rotated
and antenna adjusted to maximize radiated emission. Emissions detected within 6 dB or above limit were remeasured with the appropriate detector against the correlating limit and recorded as the final measurement.

The spectral plot is a summation of a vertical and horizontal scan. The spectral scan has been corrected with the associated transducer factors (i.e. antenna factors, cable loss,
amplifier gains, and attenuators.

3 An inverse proportionality factor of 20 dB per decade (20 log (10/3) = 10.5 dB) has been used to normalize the specification limit to a measurement distance of 3
meters to determine compliance.
