Carrier Frequency Drift measurement
The measurement of the Carrier Frequency Drift (Carr Freq Drift softkey) 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 50µs.
With Clear/Write trace mode and single sweep operation the selected number of sweeps will be
processed and according to the RF Test Specification the results of all sweeps will be compared with
the defined tolerance. If a different trace mode is selected, the analyzer can alternatively combine
several traces and determine the measurement results from the resulting trace.

Relative Transmit Power (EDR) measurement
The measurement of the Relative Transmit Power (Rel TX Power softkey) is an enhanced data rate
measurement (EDR). It determines the average transmission power of the GFSK and DPSK modulated
parts of the signal and calculates the ratio of those values.
The measurement results must conform to the requirement:
• (P
GFSK
– 4dB) < P
DPSK
< (P
GFSK
+ 1dB)
