FMCW Tank Level Probe Test Procedure

Question: We want to obtain FCC certification for our frequency modulated continuous wave (FMCW) level probe radar (LPR) device. Which test procedure should we use?

Answer: FMCW LPR devices fall under FCC . However, LPR devices for use only in a metal or a concrete tank, which provide some level of attenuation, may be certified in accordance with 47CFR§15.31(g) by showing compliance with the provisions of , with the LPR device installed inside the tank and measurements taken outside the tank using the measurement procedures in ANSI C63.10.

FMCW LPR devices for use in tanks that are neither metal nor concrete are subject to certification under 47CFR§15.256 and must follow the published FCC measurement procedures listed below:

  • 890966 D01 Level Probing Radar v01
  • TR14-1007 Measurement of FMCW provides background information on the derivation of the method for calculating the average of FMCW LPR transmissions, and measurements to confirm the calculated results.

 


Test Site for FCC Part 15 and 18 Devices Below 30 MHz

Question: Does the FCC allow us to measure our Part 15 and Part 18 devices below 30 MHz in a location other than an open area test site (OATS)?

Answer: With respect to Part 15 and Part 18 devices, the short answer is that all attempts must be made to perform the measurements on an OATS at the applicable limit distance before measurements at an alternate test site, or at a distance less than the limit distance, are acceptable to demonstrate compliance with the emission limits.

47CFR§15.31 stipulates the test site requirements. states that field strength measurements shall be made, to the extent possible, on an OATS. Test sites other than OATSs may be employed if they are properly calibrated so that the measurement results correspond to what would be obtained on an OATS.

FCC certification or verification of equipment such as perimeter protection systems, carrier current systems, and systems employing a leaky coaxial cable as an antenna, require installation site measurements to be performed at a minimum of three installations that can be demonstrated to be representative of typical installation sites。

斗地主达人 requires that to the extent practical, the device under test shall be measured at the distance specified in the appropriate rule section。

Test sites other than OATSs, such as anechoic chambers, may be employed only if calibrated so that the measurements correspond to those obtained on an OATS。

Since there are no standards for validation of test sites below 30 MHz, calibration must be obtained by other means, such as performing measurements at an alternate test site and comparing to measurements obtained on an OATS. Statistical analysis of the measurement data from several similar devices may be required to show correlation between the measurements from the alternate test site and an OATS. The limit distance below 30 MHz is 30 meters or more, and in most anechoic chambers it is not possible to perform measurements at such distances. Without further analysis and comprehensive testing, this may make it difficult to show correlation between measurements taken on an OATS at distances greater than the dimensions of the anechoic chamber, and measurements taken at the same distance in the anechoic chamber.

For devices, MP-5, Section 2.1 also permits the use of test sites other than OATSs only if it can be shown that the results obtained at the alternate location can be correlated to those obtained on an OATS. Sufficient tests must be conducted to demonstrate that the alternative site produces results that correlate with the results from an OATS.


Changing an FCC ID

Question: Please advise us on the procedure for changing an FCC ID.

Answer:斗地主达人 Under 2.933(b), the FCC allows a change in ID when there is no change in design, circuitry or construction of the certified device. The procedure requires a new application for equipment authorization, including specific supporting documents.

Additional requirements for the application process are in large part dependent on the status of the party requesting the change in ID and their relationship to the original grantee.

 published October 17, 2014 defines the procedures to request a change in FCC ID based on different circumstances.


EN 300 328 Version Change

Question: We understand that EN 300 328 V1.7.1 will cease to exist as a harmonized standard on December 31, 2014, and will be replaced by EN 300 328 V1.8.1. Are there significant differences between the two versions?

Answer: There are in fact significant differences between V1.7.1 and V1.8.1. A test report written to comply with V1.7.1 will not meet the requirements of V1.8.1. Devices will need to be reassessed. This includes existing devices which will continue to be placed on the market.

The primary reasons for the major differences between V1.7.1 and V1.8.1 are interference in the band and power measurement challenges.

We cannot list here all of the differences between V1。7。1 and 1。8。1, however some of the major changes in V1。8。1 include:

  • A split between FHSS and non-FHSS devices, and within each of these splits, a distinction between adaptive and non-adaptive modes.
  • Mandatory spectrum sharing requirements – Medium Access Protocol is replaced by “Adaptivity” (common in other ETSI EN standards such as EN 300 220, EN 300 440, etc.)
  • Test methods introduced for various technologies
  • Clearer requirements and test methods, as requested by TCAM, the European Commission, and the industry.

There are also new requirements for the test reports; a sample of one such requirement, for EUT Operation information, is provided in Annex E of EN 300 328 V1.8.1.

A brief summary of some of the differences between EN 300 328 V1。7。1 and V1。8。1 is shown in the following chart:

India – BIS Expands Safety Approval Scheme

The Department of Electronics and Information Technology (Deity) in India recently announced an expansion to the scope, including new products, of the Electronics and Information Technology Goods (Requirements for Compulsory Registration) Order, 2012。

Once the newly adopted scope expansion notification is published in the Gazette, it is anticipated that manufacturers will have six (6) months to comply, and that the inclusion of new products is likely to come into force in two timelines:

  1. All new products except batteries - 4/15/2016
  2. Batteries - 7/15/2016

The significance of the inclusion of new products is:

  • Power adapters and batteries that will be imported independently and/or will be used with products not covered by the mandatory registration.
  • Magnetic stripe readers are not considered to be smart card readers.
  • The category of mobile phones is expected to be wide and include many enterprise products that support cell phone technology/functionality. It is expected that there will be further clarification on which product types are considered to be included within the new scope, and which ones are not included within the new scope.

斗地主达人The BIS approval system has increased the scope of product types to which the scheme applies but the processes and procedures of BIS approval have not been changed.
