 Parameters of the pulses in a sequence can be swept across a range of values. This turns the sequence in a
 multi-dimensional measurement.
 
+**Physical units**

 Pulses in pulse_lib are specified in the physical units in the context of the target device:
 * Amplitudes are specified in millivolts
 * Time is specified in nanoseconds
 * MW pulses are specified for a specific qubit and resonance and drive frequency in Hz
 * Channels are identified with a logical name
 
+**Quantum device signal processing**
+
 Pulse_lib translates the specified pulse sequence to output signals of the AWG. It takes care of:
 * Phase coherence of pulses per qubit
 * Capacitive coupling of plunger and barrier gates of quantum dots using a virtual matrix
