Below are the questions asked during the live event, along with their respective answers.
Q: Can Anritsu equipment be used for meeting both European and FCC standards? Are there different products? If so what are the differences?
A: Yes, both FCC for U.S. and Radio Equipment Directive (RED) and ETSI for Europe could be evaluated. Fundamentally, these are different standards with different criteria and thresholds but they share many of the same test parameters and test cases.
Q: What exact role does the 5G tester play in testing for EMC?
A: To provide RF and protocol signaling needed to simulate real environments of operation for a device. Also to provide downlink signaling and control the device for uplink transmission. The 5G tester is also capable of measuring many of the test parameters such as TRX RF measurements or throughput.
Q: Where does RF exposure testing come into play and can you use the Anritsu 5G tester for that?
A: RF exposure is another regulatory validation subject for the effect and absorption of RF energy in the tissue. Although it is fundamentally a different set of measurements to show compliance, it uses the same 5G Tester to establish the required conditions and operate the device under test. Anritsu’s MT8000A and MT8821C are used widely in the industry for validation of RF exposure for 5G, 4G, and legacy technologies.
Q: In sub-6 to EMC (Immunity), do you have a study of when the intra-band is less immune than inter-band? Taking into consideration the throughput.
A: Not sure I understand the question. Can you elaborate? You can submit another question by accessing the on-demand version of the presentation.
Q: Is it true that there is less concern for PIM (passive intermodulation) from on-site equipment for 5G systems versus existing PIM problems for 4G systems?
A: I am not sure what is “on-site” equipment. The test instruments do not cause any PIM.
Q: What are the challenges for creating and maintaining quiet zone in dff chamber?
A: Size of the chamber and orientation of the device. Bigger QZ require bigger chambers and potentially larger reflectors, both adding to the cost, weight, and size of a chamber.
Q: If I choose um frequency band to measure all the specified characteristics, can I test it with other connections (other bands connected) to simulate a real situation when carrier aggregation happens?
A: Yes, the MT8000 and 8821C both support, Carrier Aggregation, and interband and intraband handovers. All measurements are readily available and can be performed for any of the supported band combinations on the device without the need to terminate and re-establish connection.
Q: With the MS2090A, can I validate the performance of the gNB and check the full compliance of 3gpp?
A: MS2090A is capable of measuring many operational parameters in the field. For a complete overview of all measurements and 3GPP coverage please contact Anritsu.
Q: Do you have any Radio EMC standards for 5G?
A: Yes, the global 5G standards are listed at the beginning of the presentation. Download the PDF of the slides for that information. Available in the on-demand presentation.
