The form must be completed by the applicant and submitted to Nemko before testing is started. Preparation of Equipment for Testing Note (a): Number of samples for testing The following samples are needed for FCC 15D testing: RF Conducted Tests: One sample with a 50 ohm antenna connector (preferably SMA Female). Only one antenna connector is needed for these tests even if the equipment has more than one antenna. Monitoring Tests: One sample with 50 ohm antenna connectors fitted to all antennas (preferably SMA female). Additionally we need a companion device that will work together with the EUT, the companion device must also have antenna connectors on all antennas. Radiated Tests: One sample with integral antennas. This sample will be used to measure Antenna Gain, Part 15B and Power-Line Conducted tests. Note (b): Burst Mode All RF tests are performed with the EUT in force transmit, aka burst mode. Software and necessary programming tools must be submitted to Nemko together with the test samples before start of testing. Note (c): Monitoring Tests Monitoring tests are performed in normal operating mode by establishing a connection from the handset (or the initiating device) to the base station (or the responding device). Most tests are performed by establishing connections from the initiating device to the responding device and observing which channel and/or timeslot is used. For monitoring tests we need a EUT and a Companion device that both have antenna connectors on all antennas (preferably SMA female, again). Additionally, we need access to the CLK100 signal on the Base Station, this is necessary because some of the tests require that the interferers are synced to the DECT frame. Note (d): Connection to an external power supply Means of c…
