+\section{General Description}
+The 5108 Sampler is a 8hp EEM module part of the ARTIQ Sinara family.
+It adds analog-digital converting capabilities to carrier cards such as 1124 Kasli and 1125 Kasli-SoC.
+
+It provides 8 analog-to-digital channels, each exposed by a BNC connector.
+Each channel supports input voltage ranges from \textpm 10mV to \textpm 10V.
+All channels can be updated simultaneously.

+\section{Example ARTIQ code}
+The sections below demonstrate simple usage scenarios of the 5108 Sampler card with the ARTIQ control system.
+They do not exhaustively demonstrate all the features of the ARTIQ system.
+The full documentation for the ARTIQ software and gateware is available at \url{https://m-labs.hk}.
+
+\subsection{Get input voltage}
+The following example initializes the Sampler card with 1x gain on all ADC channels.
+Sample all ADC channels at the end.
+
+\inputcolorboxminted{firstline=9,lastline=21}{examples/sampler.py}
+
+\subsection{Voltage-controlled DDS Amplitude (SU-Servo Only)}
+The SU-Servo feature can be enabled by integrating the 5108 Sampler with 4410 DDS Urukuls.
+Amplitude of the DDS output can be controlled by the ADC input of the Sampler through PI control, characterised by the following transfer function.
+\[H(s)=k_p+\frac{k_i}{s+\frac{k_i}{g}}\]
+In the following example, the amplitude of DDS is proportional to the ADC input from Sampler.
+First, initialize the RTIO, SU-Servo and its channel with 1x gain.
+
+\inputcolorboxminted{firstline=10,lastline=17}{examples/suservo.py}
+
+Next, setup the PI control as an IIR filter. It has -1 proportional gain $k_p$ and no integrator gain $k_i$.
+
+\inputcolorboxminted{firstline=18,lastline=25}{examples/suservo.py}
+
+Then, configure the DDS frequency to 10 MHz with 3V input offset.
+When input voltage $\geq$ offset voltage, the DDS output amplitude is 0.
+
+\inputcolorboxminted{firstline=26,lastline=30}{examples/suservo.py}
+
+SU-Servo encodes the ADC voltage in a linear scale [-1, 1].
+Therefore, 3V is converted to 0.3.
+Note that the ASF of all DDS channels are capped at 1.0, the amplitude clips when ADC input $\leq -7V$ with the above IIR filter.
+
+Finally, enable the SU-Servo channel with the IIR filter programmed beforehand.
+
+\inputcolorboxminted{firstline=32,lastline=33}{examples/suservo.py}
+
+A 10 MHz DDS signal is generated from the example above, with amplitude controllable by ADC.
+The RMS voltage of the DDS channel against the ADC voltage is plotted.
+The DDS channel is terminated with 50\textOmega.
