Format Data: Numeric Data (Remote Command Only)
This command specifies the format of the trace data input and output. It specifies the formats used for
trace data during data transfer across any remote port. It affects only the data format for setting and
querying trace data for the :TRACe[:DATA], TRACe[:DATA]?, :CALCulate:DATA[n]? and
FETCh:SANalyzer[n]? commands and queries.
Remote Command
494
<n> - is the trace that will be used
<threshold> - is the level below which trace data peaks are ignored. Note that
the threshold value is required and is always used as a peak criterion. To
effectively disable the threshold criterion for this command, provide a
substantially low threshold value such as –200 dBm. Also note that the
threshold value used in this command is independent of and has no effect on
the threshold value stored under the Peak Criteria menu.
<excursion> - is the minimum amplitude variation (rise and fall) required for a
signal to be identified as peak. Note that the excursion value is required and is
always used as a peak criterion. To effectively disable the excursion criterion
for this command, provide the minimum value of 0.0 dB. Also note that the
excursion value used in this command is independent of and has no effect on
the excursion value stored under the Peak Criteria menu.
Values must be provided for threshold and excursion. The sorting and display
line parameters are optional (defaults are AMPLitude and ALL).
Note that there is always a Y-axis value for the display line, regardless of
whether the display line state is on or off. It is the current Y-axis value of the
display line which is used by this command to determine whether a peak
should be reportedSorting order:
AMPLitude - lists the peaks in order of descending amplitude, with the
highest peak first (default if optional parameter not sent)
FREQuency - lists the peaks in order of occurrence, left to right across the
x-axis.
TIME - lists the peaks in order of occurrence, left to right across the x-axis.
Peaks vs. Display Line:
ALL - lists all of the peaks found (default if optional parameter not sent).
GTDLine (greater than display line) - lists all of the peaks found above the
display line.
LTDLine (less than display line) - lists all of the peaks found below the
display line.
