7.3.55 Data Type
Lets you save IQ data from the measurement using a specified file type (CSV, SDF,
TXT, BIN, BINX, BINF, ORB).
CSV
Comma-Separated Values. Excel compatible format. Plain text roughly three times the
size of BINF
TXT
Text format. Plain text roughly three times the size of BINF
SDF
Format developed for Keysight 89600 VSA Software. Note that due to differences in the
internal file structure, SDF files saved by X-Series are not guaranteed to work perfectly
with 89600
BIN
Interleaved 16-bit Q15 signed IQ file, in Big Endian format. Q15 is a DSP format in which
the most significant bit is the sign bit, followed by 15 bits of fraction. The Q15 number
has a decimal range between -32768 and -32767. The data is scaled to fit within this
decimal range
BIN files do not include sampling rate information inside the file, there will be associated
txt file including sampling rate and scaling information
BINX
Interleaved 16-bit Q15 signed IQ file, in Little Endian format. The data is scaled to fit
within the decimal range
BINX files do not include sampling rate information inside the file, there will be
associated txt file including sampling rate and scaling information
BINF
32-bit IEEE 754 floating-point number in Little Endian format. The data is raw IQ data
BINF files do not include sampling rate information inside the file, there will be
associated txt file including sampling rate information
ORB
Format developed for Keysight ORAN Studio. This format is only supported by 5GNR,
