Analyzing Recorded I/Q Data
Optionally, raw, unprocessed I/Q data is recorded to a separate file during recording
(see
Additional information on the I/Q data is stored in the CSV data list, indicating where in
the
.iq
file the I/Q data for a specific data set starts and how many samples it con-
tains. You can use this information to synchronize the raw I/Q data with the evaluated
measurement data for each data set.
You can also use the stored I/Q data to reproduce the measured signal on a signal
generator. Using the R&S
ARB
Toolbox, for example, you can convert the
.iq
data file
to a
.wv
file.
To convert the .iq data file to a .wv file
1. In the R&S
ARB
Toolbox, right-click the
.iq
data file.
2. Select "Convert" > "Convert from Data".
3. Select the following settings for the data format:
● "File Type": "Binary"

● "Endianness": "Little-Endian (x86)"
● "Precision": "32 Bit"
● "Signedness": "Signed (Two's Complement)"
