chips, 2 samples per chip, 1 sequence length per snapshot.
1) 0.95, 4.9 & 5.8 GHz characteristics are SISO
2) Based on a verified average data acquisition rate of ~20 Mbytes/S when logging data to hard disk in real
time (needed for long measurement runs).
3) Based on a verified average data acquisition rate of ~80 Mbytes/S when not logging data to hard disk in
real time (valid for short measurement runs).
CRC-Chanprobe can be operated in SISO or SIMO modes. A 32-element switched uniform circular array
and a 32-element 3D cross array have been implemented for use at the receiver. Both arrays employ
quarter-wavelength monopole antennas for the reception of vertically polarized waves.
