Test Steps and Description
Signaling PER
This test step must be a child step of
. This test step performs signaling PER
measurement.
Step Settings
– Repeat: Set the number of PER readings to be acquired within the test.
– Downlink (DL) Power: Select the DL power calculated depending on the Systems Offset.
– System Offsets: Set system offset for Zigbee channels. If the selected channel is not listed in the
System Offsets, the software will interpolate the offsets using the two nearest channels. This setting is
exclusive to Signaling PER. For example, the software will interpolate the offsets of the selected
channel 8 using the values from channel 6 and 11.
– PER limit: Set the upper limit of PER. Results that exceed this PER limit will be reported as Fail.
– Packet Count: Set number of packets sent to the DUT from 34999B module to calculate PER.
– Early Fail Count: Set the maximum number of consecutive failed received packets before the engine
reports a 'Pass' or 'Fail' verdict. For example, setting Early Fail Count at three would only report 'Fail'
when the test measured three consecutive failed received packets. The count will restart to zero
whenever there is a 'Pass' packet measured.
– Scan Delay: Set the time delay (milliseconds) between each packet request. This is dependent on the
response time of the DUT. The value set should be slightly longer than the beaconing period of DUT.
