Settings General/Demod
Opens the "General Settings" or the "Demod Settings" dialog box. For details see
chapter 4.2, "General Settings Dialog Box (K91)", on page 87 or chapter 4.3, "Demod
Settings Dialog Box", on page 97.
Alternatively, the "General Settings" dialog box is opened as follows:
●
FREQ key, with focus on the "Frequency" field
●
AMPT key, with focus on the "Signal Level" ("RF") field
●
TRIG key, with focus on the "Trigger Mode" field
Display List/Graph
Configures the result display. The measurement results are displayed either in form of
a list of measurement points or as a graphical trace.
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).
Remote command:

For result queries see chapter 5.8, "FETCh Subsystem (WLAN)", on page 168
PVT
Opens the PVT submenu to select the Power vs Time measurement results.
The PVT result displays show the minimum, average and maximum levels measured
over the full range of the measured input data, or over complete PPDUs displayed
within the gating lines if gating is switched on. The results are displayed as a single
PPDU. Using screen B in full screen provides additional power information during this
measurement.
