Bluetooth Marker Behavior
Bluetooth markers one and two have predetermined settings that are implemented when a payload data type
is selected and the waveform is generated. A waveform is regenerated when a new payload data type is
selected while the modulation format is on. These predetermined settings will override the current marker
settings if they are different. However they do not affect the ALC hold and the alternate amplitude marker
functions. But they will affect the RF blanking function. After the waveform has been
generated/regenerated, you can modify the predetermined settings to suit your measurement needs. The
following list explains the predetermined settings for marker one and two according to the selected payload
data type:
Truncated PN9 or 8-bit
pattern
Marker one outputs a five-sample-point wide pulse (500 ns) at the EVENT
1 rear panel connector, and marker two implements RF blanking during
the time that the Bluetooth signal is low.
Continuous PN9 Marker one outputs a 1 MHz clock signal at the EVENT 1 rear panel
connector, and marker two outputs a 216 µs gated pulse signal at the
EVENT 2 rear panel connector that aligns with the transmission of the
payload data.
