Figure 7-8: I and Q values calculation and conversion
3. Use an ASCII editor which is able to handle binary data. Create and add the follow-
ing mandatory tags before this binary data set can be further processed:
● TYPE
● CLOCK
● LEVEL OFFS
An example of the SICO.wv file contents could be:
{TYPE: SMU-WV, 0}{CLOCK: 10e6}{LEVEL OFFS: 3.010300,0.000000}
0000FF7F8E27BB79 ... 72D8BB79
To simplify the example, the checksum is set to 0, i.e. the instrument does not eval-
uate a checksum.
Tip: The tags TYPE, CLOCK, LEVEL OFFS and WAVEFORM are mandatory for each
waveform. All other tags are optional and can be inserted after the TYPE tag in
arbitrary order.
4. Pack the binary data into a WAVEFORM tag with the described structure.
{WAVEFORM-Length: #I0Q0I1Q1I2Q2 ... InQn}
● Calculate the Length
Length = Number of I/Q pairs * 4 + 1 = 20*4 + 1 = 81 bytes
● Place the string {WAVEFORM-81:# at the beginning of the data set
● Place the symbol } at the end of the data set
The contents of the waveform file SICO.wv for 20 I/Q pairs is now ready for opera-
tion and reads:
{TYPE: SMU-WV,0}
{CLOCK: 10e6}
{LEVEL OFFS: 3.010300,0.000000}
{WAVEFORM-81:#I0Q0I1Q1...InQn}
