\section{General Description}
|
||||||
|
The 5432 Zotino is a 4hp EEM module and part of the ARTIQ/Sinara family. It adds digital-analog conversion capabilities to carrier cards such as 1124 Kasli and 1125 Kasli-SoC.
|
||||||
|
|
||||||
|
It provides four groups of eight analog channels each, exposed by one 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.

\subsection{Setting 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 channels 0, 1, 2, and 3 respectively. Voltages of all 4 channels are updated simultaneously with the use of \texttt{set\char`_dac()}.

\section{LEDs}
|
|
||||||
|
|
||||||
5632 DAC Fastino provides eight user LEDs in the front panel. These are directly accessible in the ARTIQ RTIO. Four additional LEDs indicate, respectively, power good (\texttt{PG}), ??? (\texttt{FD}), overtemperature (\texttt{OT}), and gateware or initialization error (\texttt{ERR}).
|
|
||||||
|
|
||||||
\sysdescsection
|
|
||||||
|
|
||||||
5632 DAC Fastino should be entered in the \texttt{peripherals} list of the corresponding core device in the following format:
|
|
||||||
|
|
||||||
\begin{tcolorbox}[colback=white]
|
|
||||||
\begin{minted}{json}
|
|
||||||
{
|
|
||||||
"type": "fastino",
|
|
||||||
"ports": [0],
|
|
||||||
"log2_width": 0 // select 0 to 5, default is 0
|
|
||||||
}
|
|
||||||
\end{minted}
|
|
||||||
\end{tcolorbox}
|
|
||||||
|
|
||||||
Replace 0 with the EEM port used on the core device. Any port may be used on the core device side. Despite providing two EEM ports, Fastino only requires one of two under ARTIQ control. This should always be \texttt{EEM0}. If connected, \texttt{EEM1} will be ignored.
|
|
||||||
|
|
||||||
The \texttt{log2\_width} field accepts a number from 0 to 5 inclusive and represents (in powers of two) the number of DAC channels packed into a single RTIO write (1 to 32). This allows and defines the use of \texttt{set\_group()} functions rather than \texttt{set\_dac()} as in examples given below.

\subsection{CIC interpolators}
|
|
||||||
|
|
||||||
Fastino gateware features dynamically configurable CIC (cubic B-spline) interpolators, defined individually by channel, with interpolation rates from 1 (2.55 MSPS) to 65536 (39 SPS). For more details, see manual documentation on ARTIQ driver functions \texttt{stage\_cic} and \texttt{apply\_cic}.

\section{General Description}
|
|
||||||
|
|
||||||
The #1 is a 4hp EEM module, part of the ARTIQ/Sinara family. It adds digital-analog conversion capabilities to carrier cards such as 1124 Kasli and 1125 Kasli-SoC. It is closely related to the #2 and the two cards share a compatible output interface.
|
|
||||||
|
|
||||||
It provides four groups of eight analog channels each, exposed by one 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.

||||||

||||||
\subsection{Setting output voltage}
|
|
||||||
|
|
||||||
The following example initializes the #2 card, then emits 1.0 V, 2.0 V, 3.0 V and 4.0 V at channels 0, 1, 2, and 3 respectively. Voltage of all 4 channels is updated simultaneously with the use of \texttt{set\char`_dac()}.

\subsection{Triangular wave}
|
|
||||||
|
|
||||||
The following example generates 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.
