R&S®FS-K8 Bluetooth® Application Firmware
Output Power
The output power measurement determines the maximum and average output power during a burst oft the equipment under test. For this purpose a complete packet is recorded in the time domain.The peak value is determined from the complete contents of the measurement curve, whereas the average power is calculated from an area of at least 20% to 80% of the burst.
Adjacent Channel Power
The measurement of the Adjacent Channel Power determines the power of all adjacent channels. This measurement is limited to the available Bluetooth frequency band, which means that at maximum 79 channels will be measured. (39 lower channels + Tx channel + 39 upper channels).
Modulation Characteristics
The measurement of the modulation characteristics determines the maximum frequency deviation of all 8 bit sequences of the payload. Additionally the average value of the maximum frequency deviation of a packet will be calculated.
Initial Carrier Frequency Tolerance (ICFT)
The measurement of the Initial Carrier Frequency Tolerance determines the carrier offset of the four preamble bits. According to the RF Test Specification the calculation of the carrier offset is performed from the middle of the first preamble bit to the middle of the bit following the preamble.
Carrier Frequency Drift
The measurement of the Carrier Frequency Drift determines the maximum frequency drift between the average value of the preamble bits and any 10 bit group of the payload. Additionally the maximum drift rate between all 10 bit groups in the payload is determined every 50s.
