Trace Data CSV File

Scroll Contact Us Home Prev Top Next More

Trace data can be saved as a *.CSV file. The *.CSV file contains digital data separated by commas. One (active) trace data or all traces of the active channel are saved to the file.

The *.CSV file contains comment and trace data lines. Comments start from the «!» symbol.

Before saving the *.CSV file, activate the desired channel (See Active Channel Selection). Next, set the trace type, value delimiter type, and other parameters in the Save Trace Data submenu (See the table below). If only the active trace will be saved, activate the desired trace (See Active Trace Selection). Then, click the Save... button to save the values to the file.

Parameter	Definition
Scope	Type of trace to be saved: •Active trace. •All Traces — all traces of the active channel.
Format	Data save format: •Displayed— the format in which the trace is set (See Format Setting). •Real-Imag — real and imaginary parts. •dB-Angle — logarithmic magnitude in dB and phase in degrees.
Comment	Enable/disable the entry in the comment file. The comment contains 3 lines: 1.Model, serial number, software version. 2.Save date (in the dd.mm.yyyy hh:mm:ss format). 3.The name of the saved parameters and their dimensionality.
Stimulus	Enable/disable recording to the file frequency at measurement point.
Decimal Separator	The type of delimiters between stored values, as well as the type of decimal separator: •System — delimiters defined in regional settings are used. •Point — decimal separator is point, value separator is comma.

The active trace data is saved to *.CSV in the following format:

! COPPER MOUNTAIN TECHNOLOGIES, {model}, {serial number}, {TRVNA version}
! Date: dd.mm.yyyy hh:mm:ss
! Stimulus(Hz), {parameter [dimension]}
F[0],	Data1,	Data2
F[1],	Data1,	Data2
. . .
F[N],	Data1,	Data2

F[n] — frequency at measurement point n.

Data1 — trace response in rectangular format, real part in Smith chart and polar format.

Data2 — zero in rectangular format, imaginary part in Smith chart and polar format.

The all traces of active channel are saved to *.CSV in the following format:

! COPPER MOUNTAIN TECHNOLOGIES, {model}, {serial number}, {TRVNA version}
! Date: dd.mm.yyyy hh:mm:ss
! Stimulus(Hz), {parameter 1 [dimension]}, ... {parameter N [dimension]}
F[0],	Data11,	Data21,	Data22,	Data22,	. . .	Data1N,	Data2N
F[1],	Data11,	Data21,	Data22,	Data22,	. . .	Data1N,	Data2N
. . .
F[N],	Data11,	Data11,	Data22,	Data22,	. . .	Data1N,	Data2N

F[n] — frequency at measurement point n.

Data1N — trace response in rectangular format, real part in Smith chart and polar format.

Data2N — zero in rectangular format, imaginary part in Smith chart and polar format.

Editing Saving Parameters
