At export, the sample indexes are written in scientific notification.
If you create a mask manually in a CSV file, you can write the indexes simply as intergers.
The file should contain 1000 pairs of min-max values.
TXT Format
TXT files are ASCII files that contain only amplitude values in divisions but no time values.
Amplitude values are separated by commas. Pairs of values are listed as two subsequent
single values, without any identification. There is no comma at the end of the file.
Example: TXT file
4.00,4.20,4.05,4.25,4.08,4.28,....., -4.05,-4.25,-4.00,-4.20
BIN Format
BIN files contain binary amplitude values only but no time values. Each value has a word
size of 8, or 16, or 32 bit, the word size is the same throughout the file.
Words are given in Big Endian order - beginning with the MSB (Most Significant Byte)
and ending with the LSB (Least Significant Byte). Pairs of values are listed as two sub-
sequent single values, without any identification.
9.2 Working with Masks
Masks define a frame with which you can compare the signal values. You can load pre-
configured masks or define your own masks based on existing waveforms. When you
perform a test, you can define which actions are to be taken upon violation of the mask
limits.
Masks are displayed in the color used for reference waveforms.
