●
Rise Time, IEEE802.11b, g
Shows the rise time of the pulsed signal in µs. This is the time period the signal
needs to increase its power level from 10% to 90% of the maximum resp. the aver-
age power depending on the reference power setting. For better orientation, the
table also shows the corresponding limits specified in the standard.
●
Fall Time, IEEE802.11b, g
Shows the fall time of the pulsed signal in µs. This is the time period the signal
needs to decrease its power level from 90% to 10% of the maximum resp. the
average power depending on the reference power setting. For better orientation,
the table also shows the corresponding limits specified in the standard.
●
Mean Power, IEEE802.11b, g
Shows the mean burst power in dBm.
●
Peak Power, IEEE802.11b, g
Shows the maximum burst power in dBm.

3.9.2.3 Result Display for MIMO Measurements
For MIMO measurements (IEEE 802.11ac or n (MIMO) only) the results are provided
as an overview of all data streams in the Global Result Summary (List 1), and for the
individual streams in separate result summaries (List 2). To switch between the two
views, use the "Display Graph/List1/List2" softkey. To view more details for the individ-
ual summaries, select the table and then press the "Split Screen/Maximize Screen" key
(
).
