Packet Bytes SCO ← Meas Setup ← Output Power
Defines the number of payload bytes that are transmitted in a packet. For SCO pack-
ets, the payload length must be adjusted because those packets have no payload
header.

Power Class ← Meas Setup ← Output Power
Selects one of the Bluetooth power classes (1 to 3). The selection of the power class
determines the limits. The default setting is power class 1 (100 mW).

Points / Symbol ← Meas Setup ← Output Power
Defines the number of measurement samples per symbol. For Basic Rate measure-
ments, the possible values are 2, 4, 8, 16, 32. The default value is 4. For EDR meas-
urements, the default value is set and cannot be changed.
The RF Test Specification requests an oversampling factor of at least 4. With this over-
sampling factor a 5 Slot Packet corresponds to 12500 measurement samples (= 2500
samples / slot).

Antenna Gain ← Meas Setup ← Output Power
Defines a level offset in order to take the gain of an antenna into account for displaying
power values. The default setting is 0 dB. Offset values that are larger or smaller than
0 dB activate the enhancement label "TDF" at the right diagram border.

Find Sync ← Output Power
Opens a dialog box to set the signal processing functions of the analyzer. They are
necessary to determine the position of the first preamble bit p
0
by correlation with the
sync word. Thus, a sufficient record length of the FM demodulated signal is necessary.
For further information refer to "Position of a Bluetooth burst" in chapter 3, "Instrument
Functions for Bluetooth Measurements (K8)" , on page 20.
LAP ← Find Sync ← Output Power
Defines the lower 24 bit Lower Address Part (LAP) of the Bluetooth Device Address
(BD_ADDR) of the equipment under test (EUT).
