Managing Data, Settings, and Pictures
Results Export File Format
The Results Export format contains trace points and/or scalar results produced by the measurement. The
file contains general information about the measurement settings at the top of the file and the results data in
the second part of the file. Groups of settings or results are headed with [text], as described below.
At the top of the file is the measurement name and the date and time data was acquired.
The first 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 specific 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 specific 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 file 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.
and a ProductSpecific 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 file == the "offset" attribute in the DataFile element. This
offset number will always start at the 19th character into the file (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.
