Confidence Level
Setting this menu key to On enables the PXT to determine the probability of whether the Pm-an
measurement will pass or fail, based on the table in 3GPP TS 36.521-1 Appendix G.4.4-2. This may cause
the Pm-an measurement to stop before the Max Frame Size has been reached.
Setting this menu key to Off enables the Pm-an measurement to run for the number of transmissions set
using the Max Frame Size menu key.

Pm-dsg
(Probability of misdetection of downlink signaling grant)
The Pm-dsg measurement is used as part of an RCT system to perform test cases in 36.521-1, section 8.4.1.
As described in this specification, this measurement sends MAC padding data to the UE and counts the
numbers of ACKs, NACKs and statDTX. Pm-dsg is the ratio (statDTX)/(NACK+ACK+statDTX).
The measurement checks whether the PDCCH has been received by the UE at all. An ACK or a NACK
implies that it has been, whereas detection of a statDTX condition implies it has not.

Max Frame Size
This setting determines the maximum number of transport blocks sent when Test Start is selected.
If Confidence Level is set to On, the test may stop before reaching the maximum
number of frames.
