If the direction of the message is outbound to the ISC board, ">\t" is inserted before the string. Outbound
commands are always a single line, so that is sufficient.
These are purely cosmetic edits to make the transmissions a bit easier to visually parse for the user.
3.5 Sweeping
Sweeping is one of the more complicated features of the ISC board.
It gives the user a glimpse at the matching quality of their load across a range of frequencies.
The 'Sweep (dBm)' button performs a sweep using dBm as the preferred unit of power for both inputs and outputs. This is
done with the $SWPD command, which also takes arguments from the adjacent lineEdits.
For an improved experience the user is provided with both a dBm and watt input, though only the dBm value is
actually used in the end. When the value in either lineEdit changes, the other is also updated:
This uses a pair of conversion functions provided for convenience.
convert_dbm_to_watt: A value in dBm is provided as the argument, and a value in watt is returned.
convert_watt_to_dbm: A value in dBm is provided as the argument, and a value in dBm is returned.
The actions of the sweep button are two-part:
Execute the sweep and parse the resulting data
Draw a plot from the data (If the sweep was successful)
