CSV File Format

ASCII text file with real-valued channel data. For n channels, there are n values in a line, separated by a separator character, and terminated with a newline (or carriage return and newline). The first line may contain channel names and units, separated in the same manner as the numeric data. If units are present, they may be any valid unit string in Twin Builder, and they must follow the channel name and be enclosed in square brackets. The channel name and unit must together be enclosed in double quotation marks.

Example:

"Time [ms]", "R1.V [V]", "C1.I [uA]"

0,4.2,2.0

1.33,4.1,1.95

2.0,3.9,1.8

Complex data is handled as follows:

• The first channel name must be "f", and may have units.
• Following channels are in pairs, either

• "Re(name) [units]", "Im(name) [units]" where Re() and Im() are for complex data in real and imaginary form, or
• "Abs(name) [units]", "Phi(name) [units]", where Abs() and Phi() specify complex data in magnitude and phase.

Name is the channel name, the same for each pair of channels. Units are optional, SI if none specified.

Example (comma-separated):

"f [kHz]", "Abs(x)[mV]","Phi(x)[rad]"
