Analog Devices Scopy

[Ahmend Studioz]

SCOPYon my ADALM2000 has been throwing an error message when trying to launch both the Oscilloscope and Volt Meter. I'm not have the problem with the Signal Generator. With the little spinning icon, the error message is "SCOPY not responding."

The oscilloscope and voltmeter shouldn't run at the same time, however, the application shouldn't crash. Do you have any steps to reproduce this issue ? What version of software/firmware are you running ?

After re-installing SCOPY from the wiki link (latest Windows release - see picture), SCOPY connects and calibrates fine. Signal generator launches fine too. When I launch Oscilloscope, "Not responding) message (see picture). I am also not able to X out of SCOPY and must use Task Manager to shut down SCOPY. I'm using Windows 10.

I'm a beginner and have built a few simple circuits following GREAT COURSES, Modern Electronics lecture series. These include an amp built with transistors, a battery tester using an integrate amp chip and an attempt at a two stage transistor amp. Sometimes I use the SCOPY Power Supply. Sometimes I use AA batteries to get up to 10 volts + and 10 volts, as called for in the diagrams on GREAT COURSES. With that voltage, I smoked transistors on two occasions. An electrical engineer friend advised to use less voltage and throw in an additional resistors to protect transistors and I've been using 4.5 volts or so. As a side note, I'm also connecting all of the grounds/ reference grounds of my AA batteries with the SCOPY ground leads.

Once I get a circuit wired up, powered up, I then start sampling voltages using my separate multi-meter and also the Oscilloscope probes to see the input and output. I usually fail the first time so, to confirm the Signal Generator is working I've connected those leads direct to the Oscilloscope leads to confirm I'm getting signal. Some trial and error.

Question - is the ADALM2000 designed to be protected by mistakes that a beginner might make? Aka, smoking transistors, connect Signal Generator leads direct to Oscilloscope (I've learned maybe one should always have a load/ resistor when doing this.) I haven't seen any visible/ physical signs of this looking at the ADALM2000 unit - aka, blue lights still on.

No luck. I uninstalled, restarted, installed your version, restarted. SCOPY connects and calibrates. When I attempt to launch oscilloscope or volt meter (closing in-between) I get "not responding". Power supply and signal generator seem to launch fine. Can AD overnight or 2nd day a new ADALM2000 and I can return the one I have for AD's analysis? I've had it for about 2 months and actively used it for about 8 hours.

I got lost after deleted INI files out of ADI and then uninstalling SCOPY. I got confused/ lost on the ADALM2000 Firmware Updates page. Firmware images, Mass Storage Update, DFU Update is all Greek to me. It looks like I'm supposed to copy and open a file in the ADAL2000. Not sure I did this but, if I did, then what? I was expected to just re-install SCOPY. Can you direct me to clear and simple step by step instructions? After SCOPY uninstalled and INI files deleted, then what exactly?

You don't have to install to reinstall the firmware just yet. Just delete the inifiles, install Scopy, and try to connect using the remote interface - basically when starting the application hit the "+" button, and add the 192.168.2.1 interface and connect to it - as described here wiki.analog.com/.../scopy

Sorry about that - I was typing in wrong IP address (missed the "2"). I uninstalled, deleted INI file, reinstalled, restarted and connect to remote device with correct IP address and it's working with initial test!

We can see "shape" of response, but the issue is amplitude value. If I found just inductor can provide 40dB gain, I will get Nobel prize (or Edison medal?) As you see, the shape is correct, and it seems it has a resonant frequency of 439 kHz but its absolute value of amplitude is not reliable at all. This is not connection issue but may be impedance mismatch or,,,, transmission evaluation is made just by voltage, and multiplied voltage by IFT may producing miracle 40 dB.

Now two BNC terminals can be connected to input and output of the circuit. Two GND clip are internally connected in the adaptor, but connect just to make it sure. (The frequency range is not so strict, but it is good habit to connect always.)

In the software named "scopy" by Analog Devices, initially it will recognize USB connection to the computer and click "connect" and the button will turn to "calibrating". Still we should not connect anything,

The board as Ch1, Ch2, and green terminal for the embedded power supply. Now let' make a simple connection of RC circuit (In my case, 1k and 0.1 uF). Red clip are in/out of DUT and black ones are GND.

Now let's go to Scopy. Indeed, all of available network analyzers are automatic for parameter setting, but NWA (network analyzer) of ADALM2000 is "full manual". All of parameter should be cared to get proper result.

First of all, I made an adaptor with two BNCs and terminal adaptor for ADALM2000. The interface of ADALM2000 is just pin header and before I made this adaptor, every time I had to puzzle its connection.

The schematic is as shown above. Ch 1 and 2 of the scope are connected to DUT (device under test). Indeed it is "counter intuitive" because one of two AWG (arbitral wave generator), AWG2 is connected to the output side of DUT. Initially I connected AWG1 and 2 for input and output, but AWG1 should be disconnected. The schematic above looks wrong, but it is the circuit measuring DUT in the direction of the image.

This is the completed adaptor for frequency response measurement. If we prepare AWG connection switch, it will be able to measure full two ports. Currently this is just for Ch1 to Ch2. Green terminal block is the power supply output inside ADALM2000. The power supply can generate max 50 mA, +/- 5V, which is suitable for quick operational amplifier circuit check.

It would be very interesting if you try to measure the gain margin and phase of the control loop of a switched source, I am thinking of buying the adalm2000 but you scared me with the 40dB gain of the inductor, very good your adapter I think the analog discovery brings it.
