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,
LTEAFDD and LTEATDD Modulation Analysis measurements, LTEAFDD and LTEATDD
CEVM measurements

7.3.72 Channel
Select data channels to save. This is only supported by 5GNR Mode’s EVM, VMA
Digital Demod, VMA Custom OFDM measurements, and by WLAN Mode’s MIMO
EVM measurement.
The <meas> param in the command must be replaced with the node of the active
