Variable Description
Its unit is seconds for time-domain traces, or a dimensionless index (0 to Npoints – 1) for frequency-domain
traces.
It defines the beginning of the next field of trace elements to be compressed. This is relative to the beginning of
the previous field.
This parameter has a default value equal to the <length> variable. Note that this parameter is used for a
completely different purpose when curve fitting (see
"CFIT" on page 117 above).
<rlimit> Repeat Limit is an optional integer.
It specifies the number of data items that you want returned, and ignores any additional items beyond that
number. You can use the Start Offset and the Repeat Limit to pick out exactly which part of the data you want
to use.
The default value is all the data.
Calculate Peaks of Trace Data (Remote Command Only)
Returns a list of all the peaks for the currently selected measurement and subopcode [n]. The
peaks must meet the requirements of the peak threshold and excursion values.
l
n = any valid subopcode for the current measurement. See the MEASure:<measurement>
command description of your specific measurement for information on the data that can be
returned.
The command can only be used with specific subopcodes, and with measurement results that are
trace data. Both real and complex traces can be searched, but complex traces are converted to
magnitude in dBm. In many measurements, specifying subopcode n=0 retrieves the raw trace
data, which cannot be searched for peaks. Specifying subopcode n=1 typically retrieves calculated
results values, which also cannot be searched for peaks.
This command uses the data setting specified by the FORMat:BORDer (see "Format Data: Byte
Order (Remote Command Only)" on page 125 ) and FORMat:DATA (see "Format Data: Numeric Data
(Remote Command Only)" on page 124 ) commands and can return real or ASCII data. If the
format is set to INT,32, it returns REAL,32 data.
The command has four types of parameters:
l
Threshold (in dBm)
l
Excursion (in dB)
l
Sorting order (amplitude, frequency, time)
l
Optional in some measurements: Display line use (all, > display line, < display line)
