Array Name Type (4 bytes) = miINT8 (1)
Array Name Length (string length of name - e.g. 10 for CenterFreq)
Array Name (including pad bytes which are 0's) (see Array Size above)
Array Data Element Type (4 bytes) = miDOUBLE (9)
SizeofArray(4bytes)=8
The Instrument Setting Value (8 bytes)
Pad Bytes: 0 or more 0 bytes to end the record on an 8-byte boundary
The actual IQ data record with values written as single precision floating point
values (miSINGLE):
The I data array is written first:
Array Type (4 bytes) = miSINGLE (7)
Array Size (4 bytes) = 56 + nameLen + padding
nameLen is the string length of the name
padding = (8 - (nameLen % 8)) % 8
