3.2 R&S Waveform

The waveform, R&S_IQ_BLE_1Mbps_1pkt_70ms_guard.ww, is a binary file containing I/Q samples that can be used through a baseband generator with ARB to create a 1 Mbps BLE modulated test data package. This waveform is compatible with all new Rohde and Schwarz signal generators like SMW200A, SMU200A, SMJ100A, SMATE200A, AMU200A, SMBV100A, AFQ100B, SMA100A, SMB100A or SMC100A.

The waveform contains a 37 byte large 1 Mbps BLE modulated package with an access address of 0x71764129.

There is a 1 ms guard time added at the beginning of the waveform and a 69 ms guard time at the end of the waveform. This leads to a 70 ms time between each package when the waveform is looped repeatedly back to back. The reason for adding the guard bands is so that each packet can be received reliably without any packages getting lost due to the limited bandwidth between the DUT and the PC running SmartRF™ Studio.
