NOTES ON THE FORMAT
Each numeric value defined in the format can be separated by a comma or any whitespace (spaces, tabs,
and new lines). The example above shows values separated by commas and white spaces. The file would
still be valid if all values were on one line as shown below.
1000000000 -20 200000 2 8 1 0 0 0
Comments can be inserted into the file and will be ignored as long as there is whitespace or a comma
separating them from the numeric values. An example of this is below.
1000000000 One GHz
-20 Maximum output power allowed
200000 Two hundred kHz sample rate
2 Two samples
8 Period of eight
1 0 0 0 Pulse waveform
If you choose to make comments in the arb files, use words instead of numbers in the comments, as
numbers in the comments will be parsed as the next input value.
6 I/Q Offset Adjustment Dialog
This applies only to notched multi-tone signals. You will need a spectrum analyzer to make this
adjustment. To null the LO feed-through for notched multi-tone signals, place a marker on the LO feed-
through signal, and then adjust I and Q offsets until a minimum amplitude is observed in the center of
the notch. You may need to alternate between I and Q offsets a few times.
