5 Ad vertising Channel Power Measurement
This step must be a child step of
. This step measures the transmit (Tx)
power of each advertising channel based on the System Offset and Power Limits set.
Step Settings
– System Offsets: Set path loss between RF I/O to DUT.
– Power Limits: Set the limit on power measurement to determine the ‘Pass’ or ‘Fail’ results of the DUT.
For example, setting the limit from -30 to 0 dBm would allow a DUT of -20 dBm to report a ‘Pass’
result.
– Measurement Timeout: Set the timeout for this test step to exit measurement. Default to 10,500
milliseconds and the range is from 100 to 300,000 milliseconds.
– ADC Noise Floor: Set the ADC noise floor for advertising channel Tx power detection and
measurement. Any RF events that occur above the set noise floor will trigger power measurement.
Defaults to -31 dBm. This is an advanced parameter that should only be adjusted if directed by
Keysight.
– ADC Capture Multiplier: Set the multiplier that increases the ADC capture points during advertising
channel Tx power detection and measurement. This is typically used when the advertising packets RF
bursts are long or when the timing between each advertising channel (Channel 37, 38, and 39) is long
during an advertising event.
– Retries: Set the number of attempts to obtain power measurement.
NOTE
If Retries are set >1 then the system will attempt additional measurements if the
results are outside of the specification limits (USL and LSL). As such correctly
setting the specification limits is important.
