+        MIXER CALIBRATION
+The program is designed to play a continuous single tone to calibrate an IQ mixer. To do this, connect the mixer's
+output to a spectrum analyzer. Adjustments for the DC offsets, gain, and phase must be made manually.
+
+If you have access to the API for retrieving data from the spectrum analyzer, you can utilize the commented lines below
+to semi-automate the process.
+
+Before proceeding to the next node, take the following steps:
+    - Update the DC offsets in the configuration at: config/controllers/"con1"/analog_outputs.
+    - Modify the DC gain and phase for the IQ signals in the configuration, under either:
+      mixer_qubit_g & mixer_qubit_g or mixer_resonator_g & mixer_resonator_g.

+# These are the 2 commands used to correct for mixer imperfections. The first is used to set the DC of the `I` and `Q`
+# channels to compensate for the LO leakage. The 2nd command is used to correct for the phase and amplitude mismatches
+# between the channels.
+# The output of the IQ Mixer should be connected to a spectrum analyzer and values should be chosen as to minimize the
+# unwanted peaks.
+# If python can read the output of the spectrum analyzer, then this process can be automated and the correct values can

+# Note that the LO leakage (DC Offset) depends on the 'I' & 'Q' powers, it is advised to run this step with no input power.
+# This will ensure that there is no LO leakage while the pulses are not played in the case where the is no switch.
