\section{General Description}
|
|
The 4410 Urukul card is a 4hp EEM module part of the ARTIQ Sinara family.
|
|
It adds frequency generation capabilities to carrier cards such as 1124 Kasli and 1125 Kasli-SoC.
|
|
|
|
It provides 4 channels of DDS at 1GS/s.
|
|
Output frequency from \textless 1 to \textgreater 400 MHz are supported.
|
|
The nominal maximum output power of each channel is 10dBm.
|
|
Each channel can be attenuated from 0 to -31.5 dB by a digital attenuator.
|
|
RF switches (1ns temporal resolution) on each channel provides 70 dB isolation.
|
|
Urukul comes with either AD9910 or AD9912 chips.

\section{Example ARTIQ code}
|
|
The sections below demonstrate simple usage scenarios of the 4410 Urukul 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}.
|
|
|
|
% Timing accuracy in the examples below is well under 1 nanosecond thanks to the ARTIQ RTIO system.
|
|
|
|
\subsection{10 MHz Sinusoidal Wave}
|
|
Both the CPLD and the DDS channels should be initialized.
|
|
|
|
\begin{minted}{python}
|
|
@kernel
|
|
def run(self):
|
|
self.core.reset()
|
|
self.cpld.init()
|
|
self.dds0.init()
|
|
self.dds0.cfg_sw(True)
|
|
self.dds0.set_att(6.)
|
|
self.dds0.set(10*MHz)
|
|
\end{minted}
|
|
|
|
If the synchronization feature of AD9910 was enabled, RF signal across different channels of the same Urukul can be synchronized.
|
|
For example, synchronized RF signal can be produced on both channel 0 and channel 1 after configuring an appropriate phase mode.
|
|
\begin{minted}{python}
|
|
@kernel
|
|
def run(self):
|
|
self.core.reset()
|
|
self.cpld.init()
|
|
|
|
self.dds0.init()
|
|
self.dds0.cfg_sw(True)
|
|
self.dds0.set_phase_mode(PHASE_MODE_TRACKING)
|
|
self.dds0.set_att(6.)
|
|
self.dds1.init()
|
|
self.dds1.cfg_sw(True)
|
|
self.dds1.set_phase_mode(PHASE_MODE_TRACKING)
|
|
self.dds1.set_att(6.)
|
|
|
|
self.dds0.set(10*MHz)
|
|
self.dds1.set(10*MHz)
|
|
\end{minted}
|
|

\subsection{DDS RAM Modulation}
|
|
Only available to AD9910 variants. Set field \texttt{dds} as an Urukul channel, \texttt{cpld} as the corresponding Urukul CPLD.
|
|
|
