Analyzing Measurement Results
Various analysis methods available with waveform analysis commands
The Agilent 4294A provides waveform analysis commands that allow you, for example, to
search for the maximum and minimum values on the waveform and analyze waveform
ripples and resonator parameters.
Use the following commands to specify the applicable range for analysis and the trace to be
analyzed.
• “ANARANG” on page 267
• “ANASEGM” on page 268
• “ANARFULL” on page 268
• “ANAODATA” on page 266
• “ANAOMEMO” on page 266
Use the following command to define the peak for analysis.
• “THRR” on page 452
NOTE
The analysis range and the peak definition specified using the above commands are
available only for waveform analysis commands. Note that the above range and the
definition are irrelevant to the search range and the peak definition available during search
using the marker or to the analysis range available during equivalent circuit analysis.
Searching for maximum and minimum values
Use the following waveform analysis commands to search for and read the maximum and
minimum values on the active trace.
• “OUTPMAX?” on page 384
• “OUTPMIN?” on page 386
• “OUTPMINMAX?” on page 386
You can perform the same function by using the marker search function to move the
marker to each of the maximum and minimum value positions and reading the
marker-specified value at each position.
NOTE
The analysis range for waveform analysis commands is specified separately from that for
marker search. Therefore, one or both of the maximum and minimum values for these
ranges may differ if these ranges are different.
Searching for peaks
Use the following commands to search for and read peak values on the active trace.
• “PEAK?” on page 397
• “NEXPK?” on page 363
• “NPEAK?” on page 364
• “NEXNPK?” on page 362
• “LMAXS?” on page 343
• “LMINS?” on page 344
