Thanks for watching! This is one simple demo that we showed at a conference, but there are countless applications that benefit from small-scale, real-time neural networks. Check out some other examples: apis.liquidinstruments.com/mnn/

@@LiquidInstruments Would be nice if people would stop using the nomenclature of "neural networks" when at most, this is machinelearning. The term "neural network" was deviced by McCulloch & Pitts back in the 1930's. Their oversimplification has nothing to do with a neural network whatsoever. Same goes for the other overused buzzword, "AI" which again, is at most just machinelearning. Sorry for the rant, I just find it misleading using these types of buzzwords. The product otherwise seems interresting.

@@Gin-toki A neural network is not a buzzword, it is something very concrete. An autoencoder is a neural architecture, that is, a kind of neural network. Yes, pre-trained neural nets are used here to denoise signals in real time. You can look up the term "denoising autoencoder" to verify.

We're glad you love Moku! The Moku Spectrum Analyzer is built on a heterodyne/FFT architecture, which means it samples entire spectra at once and isn't suited for zero-span measurements. However, the great thing about Moku is that it provides a reconfigurable suite of instruments to give you the right tool for the job. The Moku Lock-in Amplifier gives you the amplitude of the signal at a particular frequency over time. Plus, it delivers another advantage: you also have phase information available, and can output both the amplitude and phase in real time to other Moku instruments. Check it out on our website: liquidinstruments.com/products/integrated-instruments/lock-in-amplifier/ Or on KZbin: kzbin.info/www/bejne/iWjQk3mKlL9qnNE

@@LiquidInstruments Thank you for the reply! I have looked at the lock-in amplifier, however I can not find an easy way for it to do what I want. The lock-in amplifier gives me the signal amplitude vs time after demodulation. However, in a zero span measurement I want to have the Fourier transform of that signal at the specific frequency. Is that something that is possible, perhaps using other instruments or perhaps even the cloud compile?

@@eriksvanberg8536 We'd like to understand more details about your goals and setup in order to give the best response. Reach out to us at liquidinstruments.com/support/contact/ to submit your questions to an applications engineer.

Thanks for your comment! In this case, the two signals are very different. In the classic implementation the PDH sidebands are far outside the cavity linewidth and would be transmitted only very weakly to the PDtrans diode.

Thanks for catching our algebra mistake. It doesn't affect the content of the tutorial overall and we're glad you enjoyed the video. We appreciate the comment.

Thanks! If you'd like to learn more tips to optimize your PDH setup, check out our guide: www.liquidinstruments.com/the-ultimate-guide-to-pdh-locking-performing-efficient-laser-frequency-stabilization/

Thanks! With ultra-low timing jitter, an integrated Data Logger, and zero dead-time statistics and on-device histograms, the Moku Time & Frequency Analyzer accelerates experiment timelines and increases data interpretation efficiency.

@@LiquidInstruments Yeah - I get it. That's why it's neato. You mashed cool things together. Going to mash more? I mean heck what other instrumentation can supplement this - it seems like that is kind of the idea.

I have to agree that 1MV/s would be better communicated as 1V/us (us = microsec) or 1mV/ns.

Thanks for the request! We'll look into that and add to our list of video topics.

We're lucky to have Jess on our team! Hear her explain how to configure the Moku Time & Frequency Analyzer for event counting, specifically for a Hanbury-Brown-Twiss (HBT) photon counting setup. kzbin.info/www/bejne/qZuvlWN5eMpljpI

Take it for a spin! You can download the software in demo mode here: www.liquidinstruments.com/products/desktop-apps/

You can indeed choose to get very precise with the frequency configuration, but the instruments are able to address a wide range of applications that may not need that level of granularity. The instrument configuration can change in just a few seconds, and up to a minute if you're using all four instruments simultaneously in Multi-instrument Mode. You can try the software for free without the hardware in demo mode from our website, but keep in mind configuration time will be slightly longer on actual hardware. Feel free to reach out to us with any more questions!

We're glad you enjoyed this video. To continue learning, check out how to configure the Moku Time & Frequency Analyzer for advanced interval analysis. kzbin.info/www/bejne/aIXSkmaEfbOVjrM

We have apps for Windows, macOS, iPadOS, and visionOS - our software team develops these in our Canberra, Australia office.

For photon counting, oscillator characterization, FSOC, jitter analysis, pulse-width modulation decoding, and more, the Moku Time & Frequency Analyzer can do it all. Check it out: www.liquidinstruments.com/products/integrated-instruments/time-frequency-analyzer/

We describe Moku:Go as a versatile, easy-to-use, 30 MHz bandwidth solution for quick experiments and testing - but sonic screwdriver has a nice ring to it!

Thanks for the comment! We think Moku for visionOS is cool too. 😎 Android and ChromeOS are on our radar - follow us on LinkedIn to stay on top of our latest news and product updates: www.linkedin.com/company/liquidinstruments/

The fast controller is the main controller responsible for locking the laser. It can act quickly, and control actuators that act quickly (like piezos), to give you the best dynamic locking performance. The limitation of this system tends to be small dynamic range, so it saturates as the laser drifts over time. The slow controller helps by offloading some of the control authority from the fast system to a different actuator with better range, but slower speed (typically a heater element). Or to put it another way, the fast controller is designed to suppress small, fast "noise" using a piezo and the slow controller compensates for larger, slower "drift" using a heater. Together, the two give you the best of both worlds!

We're glad you enjoyed the video!

Thanks for watching! We'd love to hear more about what you plan to film with your Moku:Lab. In this video, we captured the animations using PowerPoint and recorded the software screen caps using the iPad screen recording function. We used Premier to edit the video. You can also try Camtasia for desktop screen caps and basic editing, and/or DaVinci Resolve if you have complex editing needs. For desktop screen caps, you can also use built-in the Windows screen recorder or the QuickTime screen recorder for Mac.

@@LiquidInstruments Thanks a lot for sharing. I'm trying out Moku in some of our physics experiments for teaching.

Thanks for watching, Hien! We typically use a BNC male to screw terminal connector to connect the speaker to our Moku device.

Hi Xuliang, Thanks for your comment. To learn more about Moku:Pro, you can visit our website at www.liquidinstruments.com/products/hardware-platforms/mokupro/. To make a purchase, you can email our sales team at [email protected].

Hi Mahadesh, thanks for your comment. The great thing about Multi-instrument Mode is that there’s no coding required. You simply drag and drop any of our 12 software-defined instruments to combine them in whatever setup you need. If you want to code additional custom functionality with Moku Cloud Compile, it uses standard VHDL. There are lots of free resources available online that can help you get started with VHDL. Feel free to contact to us at [email protected] and we can help you find specific resources that meet your needs.

Thanks for watching! One way to think about the OPO process is one green photon is down converted to two infrared photons. Because of energy conservation, the two resulting infrared photons must be related (correlated) in their energies. You can find more information on squeeze states, including references for further reading, at www.rp-photonics.com/squeezed_states_of_light.html

it always has to be 2 photons because if you do the calculations you will get a zero probability of finding odd numbers of photons, (just calc <n|squeezed_vac>)

Moku:Pro is music to our ears with any soundtrack! Hope you enjoyed the new music!

In general, there are two ways to change the set point. If you need a constant (DC) value, use the Input Offset field to add or subtract the set point value from the sensor input and form the error input to the PID Controller. For trajectory tracking, the set point can be given as a voltage on the second input BNC. Then, use the Control Matrix to subtract one input (the set point) from the other (the sensor signal) to again form the error that goes into the PID. For the set point of the fan and the ball in this system specifically, a potentiometer connected to one of the inputs is used to adjust the set point. Thanks for watching!

The transfer function may look slightly different in the app compared to MATLAB since the integrator saturation is enabled to prevent the ball from always going to the max height. This would add an extra pole to the equation that was not included for simplicity. We’re happy to discuss this in greater detail if you'd like. Visit the User Forum on the Support section of our website.

You can’t use the Data Logger to log digital inputs. However, the Logic Analyzer can log digital signals. They are separate instruments in the desktop app. You can learn more about our full suite of integrated instruments on our website.

An AC power adapter is included with every Moku:Go depending on the country that you live in. The specs for the AC input are 100-240 V at 1.5 A (50/60 Hz). The DC output is 12 V at 5 A.

We think so, too! Glad you enjoyed the video.
