\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.

\section{Example ARTIQ code}
|
|
The sections below demonstrate simple usage scenarios of the 5432 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()}.
|
|
|
|
\begin{minted}{python}
|
|
def prepare(self):
|
|
self.channels = [0, 1, 2, 3]
|
|
self.voltages = [1.0, 2.0, 3.0, 4.0]
|
|
|
|
@kernel
|
|
def run(self):
|
|
self.core.reset()
|
|
self.core.break_realtime()
|
|
self.zotino.init()
|
|
|
|
delay(1*ms)
|
|
self.zotino.set_dac(self.voltages, self.channels)
|
|
\end{minted}
|
|
|
|
\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.
|
|
\begin{minted}{python}
|
|
from scipy import signal
|
|
import numpy
|
|
|
|
def prepare(self):
|
|
self.period = 0.1*s
|
|
self.sample = 128
|
|
t = numpy.linspace(0, 1, self.sample)
|
|
self.voltages = 8*signal.sawtooth(2*numpy.pi*t, 0.5)
|
|
self.interval = self.period/self.sample
|
|
|
|
@kernel
|
|
def run(self):
|
|
self.core.reset()
|
|
self.core.break_realtime()
|
|
self.zotino.init()
|
|
|
|
delay(1*ms)
|
|
|
|
counter = 0
|
|
while True:
|
|
self.zotino.set_dac([self.voltages[counter]], [0])
|
|
counter = (counter + 1) % self.sample
|
|
delay(self.interval)
|
|
\end{minted}
|
|
|
|
\section{Ordering Information}
|
|
To order, please visit \url{https://m-labs.hk} and select the 5432 Zotino in the ARTIQ Sinara crate configuration tool. The card may also be ordered separately by writing to \url{mailto:sales@m-labs.hk}.
