\section{General Description}
|
|
The 5432 Zotino is a 4hp EEM module part of the ARTIQ Sinara family.
|
|
It adds digital-analog converting capabilities to carrier cards such as 1124 Kasli and 1125 Kasli-SoC.
|
|
|
|
It provides 4 groups of 8 analog channels each, exposed by 1 HD68 connector.
|
|
Each channel supports output voltage from -10 V to 10 V.
|
|
All channels can be updated simultaneously.
|
|
Channels can broken out to BNC, SMA or MCX by adding external 5518 BNC-IDC, 5528 SMA-IDC or 5538 MCX-IDC cards.

The following are cross-talk and transient behavior of Zotino\footnote{\label{zotino21}https://github.com/sinara-hw/Zotino/issues/21}.
|
|
In terms of output noise, it was measured after 15 cm IDC cable, IDC-SMA, 100 cm coax ($\sim$50 pF), and 500 k$\Omega$ $||$ 150 pF\footnote{\label{zotino27}https://github.com/sinara-hw/Zotino/issues/27}.
|
|
The DAC output during noise measurement is 3.5 V.

\section{Example ARTIQ code}
|
|
The sections below demonstrate simple usage scenarios of the 5432 DAC Zotino 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{Set output voltage}
|
|
The following example initializes the Zotino card, then emits 1.0 V, 2.0 V, 3.0 V and 4.0 V at channel 0, 1, 2, 3 respectively.
|
|
Voltages of all 4 channels are updated simultaneously with the use of \texttt{set\char`_dac()}.

|

|
|
|
|
\subsection{Triangular Wave}
|
|
A triangular waveform at 10 Hz, 16 V peak-to-peak.
|
|
Timing accuracy of the RTIO system can be demonstrated by the precision of the frequency.
|
|
|
|
Import \texttt{scipy.signal} and \texttt{numpy} modules to run this example.
