Managing Data, Settings, and Pictures Data, Settings, and Picture File Formats
Results Export File Format
The Results Export format contains trace points and/or scalar results produced by the measurement. The
fi le contains general information about the measurement settings at the top of the fi le and the results data in
the second part of the fi le. Groups of settings or results are headed with [text], as described below.
At the top of the fi le is the measurement name and the date and time data was acquired.
The fi rst group of settings is [Global Parameters]. These settings include the Measurement Frequency,
Acquisition Data, Reference Level and others.
The second group of settings is [Parameters]. These settings are speci fi c parameters which vary depending
on the measurement.
The next group is [Trace Parameters], which may not be present, depending on the measurement. Within
this group, there are parameters speci
fi c to a trace. There will be a Trace Parameters group for each
trace shown on the display.
The next group is [Results]. These are scalar results for the measurement.
Next is [Traces]. The Traces group consists of one or more [Trace] groups. There is one Trace group for
each trace. Each [Trace] group contains background information about the trace (units, number of points, x
scaling, and others depending on the measurement) at the top of the group, followed by the trace points.
Acquisition Data with Setup File (.tiq) Format
The fi le consists of two parts - the header that is in XML and the data that is in binary format.
Header.
The header consists entirely of the DataFile element. This element is broken down into
sub-elements.
1. DataSetsCollection
2. Setup
DataSetsCollection. The DataSetsCollection contains a DataDescription element, a DataSet element,
and a ProductSpeci fi c element.
Binary data.
Binary data is a sequence of Int32 values, which are IQ pairs (I,Q,I,Q, ...) in binary Little
Endian format.
To convert these values to volts, multiply the individual values by the Scaling value in the DataDescription.
The binary data starts at an offset into the fi le == the "offset" attribute in the DataFile element. This
offset number will always start at the 19th character into the fi le (starting with 1), and will always be 9
characters long.
NOTE.
You should not casually modify the XML header, because this will change the offset to the start of
the binary data.
