IQ File Summary Descriptions
Click the IQ File summary icon to display information of the saved IQ data recorded.
The data file is created in binary format. From the beginning of the file, I-phase data and Q-phase data are recorded by 4 bytes. The I-phase data and Q-phase data are recorded as a float type.
Beginning of file:
I-phase data 1 (4Byte)
Q-phase data 1 (4Byte)
I-phase data 2 (4Byte)
Q-phase data 2 (4Byte)
I-phase data 3 (4Byte)
Q-phase data 3 (4Byte)
The IQ data can be converted to power based on the following formula.
P=10Log10(I2+Q2)
P: Power (dBm)
I: I-phase data
Q: Q-phase data
