You can better understand your data by using analysis panels to apply filters, frequency domain transfers, and statistical analysis to data sets. Each analysis panel enables you to select a data channel, apply an analysis function, and capture results.
You can select from the following analysis panels:
- Curve Fit— Finds the line that best represents an input signal or input data set using a specific fitting method.
- Statistics— Performs statistical calculations on a signal.
- Histogram— Finds the discrete histogram of a signal.
- Amplitude Measurements— Performs peak amplitude measurement.
- FFT Spectrum— Computes the averaged FFT spectrum of a signal.
- Tone Measurements— Finds tones with specific amplitude and frequency parameters.
- Pulse and Transition Measurements— Returns various measurements of a specific pulse in a periodic waveform or an array of periodic waveforms, such as the period, pulse duration, and duty cycle.
- Limit Testing— Performs limit testing on a signal.
- Filter— Applies a lowpass, highpass, bandpass, or bandstop filter to a signal.
- Scaling and Mapping— Scales a signal based on a straight line.
- Resample— Resamples a signal according to specific delay and sampling interval.
- Signal Correlation— Computes the auto correlation of a signal or cross correlation of two signals.
You can open the Configured Code pane to view the programmatic implementation of your analysis panel. You can copy the code into a VI to automate the code.
Analysis panels support the following data types:
1D array of single-precision, floating-point numbers
1D array of double-precision, floating-point numbers
Analog waveform of single-precision, floating-point numbers
Analog waveform of double-precision, floating-point numbers
Resizing Data Sets to Open in Analysis Panels
If you need to open a large data set in an analysis panel, you must first trim the data to a smaller size.
Analysis panels have the following upper limits to the amount of data they can process:
1 million samples per channel when you launch analysis panels from the Interactive Analysis section
9 MB total file size when you select a data set from the Input Signal pull-down menu of an analysis panel
Complete the following steps to resize a data set:
Open the data and use the thumbnail view to select a subset of the data.
Click Crop to Frame to create a new capture of the subset. If the subset meets the upper limits criteria, you can open the subset in an analysis panel.
