If it attempts to connect to another SAS, this constitutes a new and separate registration. Suggestion: “between the CBSD and the SAS.” |\n| 2 | Footnote 2 | At what time does a sample need to be submitted to the FCC for PAG (e.g. before or after going to the test lab) . Can basic information be provided as to what is done in the PAG, what is required of the test lab and device manufacturer? |\n| 3 | a) The ability to compel the device-undertest (DUT) to operate on a channel selectable by test personnel. | This action can be accomplished by having the SAS provide a grant in the chosen channel and verifying externally that the CBSD under testis transmitting in that channel. |\n\n\n| Page | Text / area within OET Lab Report | Comment / Discussion |\n| --- | --- | --- |\n| 3 | b) The ability to vary the output power from the minimum to the maximum realizable levels and set it to a desired level. | The grant has an associated maximum EIRP value. Cycling the CBSD through a series of grant allocations with varying power and measuring the output power can provide the needed verification.\u003Cbr>Clarification on the minimum level is requested. |\n| 3 | c) As needed, the ability to continuously transmit a modulated signal (i.e., with no time bursting or signal gating applied) . | Since many CBSDs are likely to support TDLTE where transmission DL alternates with receiving UL, this would require a special mode for the radio.\u003Cbr>Please be specific about what needs may be found that would require this continuous transmission, what power levels would be used, what frequency range(s) might be tested, etc. |\n| 3 | a), b), c) | What is the essence for these test, are they intended for RF test where unit is not connected to a SAS or CBSD-SAS protocol |\n| 3 | d) The ability to enter all required SAS registration information. | CBSDs may be designed such that a significant amount of registration information is entered directly into the SAS by the CBSD vendor or by the CBSD User/Owner. Examples include the User/Owner name and contact information, antenna characteristics that apply to all units of a particular model from the CBSD vendor, EIRP capability, measurement capability, etc. There may be no provision in the CBSD software to hold or transmit all SAS registration information. |\n| 3 | e) The ability to view all information provided to the radio by the SAS. | This function can most easily and reliably be provided by an external protocol analyzer. |\n| 3 | Footnote 6 | Who determines whether a SAS test harness or actual SAS is used? I assume this would require running through the WINN Forum CBSD test cases on a certified SAS. It may be difficult for an actual SAS to run many tests designed for a SAS test harness.\u003Cbr>Could the CBSD vendor and SAS vendor work together on a test plan / execution / results to demonstrate compliance? |\n| 4 | 1.
