The regulatory requirements will give guidelines so all devices in certain range will work together in a efficient manner. Q11 – Why or what is regulatory compliant testing such as FCC ID or CE R&TTE?Ī11 – Any product on market that is considered an intentional or non-intentional short-range radiator that will share air transmission frequencies must go through compliant testing.

Q10 – What is the recommended step to submit product to compliance labs for testing?Ī10 – The basic idea would be work together with your compliance lab at every stage, and conduct a pre-compliance measurement before officially submit the EUT to final testing, the pre-compliance measurement is first taken to point out any obvious over the limit violations such as excessive fundamental or harmonic power levels, or transmitting time beyond allowed limit, so we can make corrections if there is any, before setting product up for a full compliance test. Q9 – What does DUT / EUT or UUT mean in FCC ID testing report?Ī9 – Device under test – DUT, also known as equipment under test – EUT or unit under test – UUT, is a term commonly used to refer to a manufactured product undergoing testing in labs. An example is when transmission is achieved with the use of push button, typical appliances include garage door openers, automotive remote keyless entry etc.
Q8 – What is random mode operation of remote control transmitter?Ī8 – Transmission of a signal that is not done in a pre-defined or pre-determined fashion.
To operate in this mode, limits in Paragraph 231, Section E may be applied. Q7 – What is continuous mode operation of remote control transmitter?Ī7 – It’s mode of continuous in operation that is beyond the allowed time period specified by Paragraph 231, Section A. Q6 – What is periodic mode operation of remote control transmitter?Ī6 – It’s mode of operation that has a prescribed number of burst periods and off period of transmission, typical appliances include garage door openers, automotive remote keyless entry etc. Q5 – What are typical RF lab tests that could be issues in qualifying a product?Ī5 – Fundamental power levels, occupied bandwith, spurs, harmonic products of fundamental operating frequency, unintentional radiation while turning your product off and on, all the above parameters are described by a regulatory agency’s standards, even to extent of describing the setting and placement of the test equipment and orientation of the remote control transmitter device under test. Also receivers needs to go through other tests such as susceptibility and immunity test, and here at Solidremote, we only use superheterodyne receiver modules, which can pass FCC or CE R&TTE labs test without problem. While for older generation super-regenerative receivers, it has high levels re-radiation from antenna port, so it might be a issue to get compliance testing. Most of today’s new generation receivers use super-heterodyne modules, thus has low emssion from antenna port, so meeting compliance is typically not a issue. Q4 – Is a radio receiver considered as intentional radiator and does it need to get FCC ID before marketing?Ī4 – Even though RF receivers are considered non-intentional radiators, compliance testing still needs to be done. For example, if transmission is not regulated, one continuous transmitted high power remote control should cause signal jamming in specific areas. This not only reduces the chance of interference between signals, but also promotes safety.

Q3 – Why is sharing air frequencies so important in ISM band?Ī3 – One of the benefits of the ISM band is that license is not required, however the use of ISM frequency must be done in organized and regulated manner. Be sure to consult your compliance testing labs to see if in-house re-qualifications can be made, and the necessary procedures.
This situation depends on the level and type of modification, such as antenna changes to modulation to carrier changes. Q2 – Do I have to resubmit product for qualification if the product is modified even slightly after received an FCC ID number?Ī2 – After receiving certification that test subject has been accepted by a regulatory agency, any modification normally means re-qualification. An non-intentional radiator radiates unwanted RF frequencies such as spurs and harmonics of the later, such as a DC motor when working, measures must be taken to control the radiation levels. Q1 – What is the difference between intentional and non-intentional radiation?Ī1 – An intentional radiator, normally known as transmitter, radiates a controlled frequency. Here are some common questions asked regarding FCC ID testing for typical RF remote control transmitter, should you have any questions, please let us know.
