When the instrument is started, the bode plot is shown in the program and it was verified that the RC filters are working with the cutoff at 1KHz just as designed. The connections to the input and output side of the filter is connected as follows:e the WaveGen 1 output and Oscilloscope Channel 1 input of the device is connected to the filter input, while the Oscilloscope Channel 2 is connected to the filter output, as shown in the picture below.

The waveforms software that comes up with this device has a tab called Network analyser. The PCB design and the fabricated PCB images :Īnd in order to test them, I used the bode plot feature of AD2. My main objective of using analog discovery(AD) is to build a vibration sample magnetometer (VSM) and use AD2 to source power and acquire measurements.īut before I show you how I did that, I can want to show few of the preliminary tests that I did with AD2, and show you where it succeeds and where it fails.Īs a part of developing the sample holder for the above project, I designed 20 low pass RC filters. One of the better measurements I was able to do with this system was to measure superconducting transition temperature of Nb thin film, a graph of the same is attached here.Ī preliminary test of Analog Discovery 2!

I would love to show you the block diagram but even 5 different images coudnt capture the entire block diagram (yes it was that messy!) so I have uploaded the source code at the end if anyone wants to take a look at it. I also added functions to write the obtained data in a systematic format. So, in the end, I combined parts from LS336's example and SMU's VI tree in a way that is suitable for the current requirement of measuring Resistance as a function of sample temperature. The back panel (block diagram) actually contain many sub-VI's that act as functions so one can use them in their own program. Now, however, SMU's examples didn't work well for me, in such a case, one would make a new VI, right-click on the block diagram and go to It had all the features I wanted to control from that instrument.
In the case of LS336, "Lakeshore 336 Configure heater output control parameters and acquire single reading.vi" example was just what I needed. Once installed, one can find example codes by going to HELP>FIND EXAMPLE> and searching the model number.

Luckily both LS336 and SMU had instrument drivers available.

To get started with designing such software, typically one needs to install the instrumentation driver and look into example program. There are 2 parts to any VI, the front panel, where you put all the user-controllable elements like buttons tet bar etc and logical back panel/ where all the logic for the program is written using "G" programming language. In Labview, such software are what are called VI's which stands for virtual instrument. I wanted to use LabVIEW to make a program to automate data acquisition of resistance of the sample as a function of sample temperature. Currently, Lakeshore 336 (LS336) temperature controller, B2912A Source meters (SMU) are connected in the photo below. One can connect any instruments to this break outbox using banana pin wires. Wires from the sample, temperature sensor and the heater come out of the cooler to a breakout box. The sample you see is connected thermally to a heater and a temperature sensor (cernox sensor). An image of the sample holder with the sample can be seen here. The sample is kept on a sample holder that is designed in house, keeping in mind of all the sample space constraints and to maximise the thermal conductivity between cooler and the sample. The cryostat uses a liquid helium compressor to cool down the chamber where the sample will be kept. The system I'm using comprises of a Cryostat, Temperature controller, Source meter Unit. I wanted to interface all the instruments using LabVIEW. The lab that I currently work in does electrical and magnetic measurements of specific samples at liquid helium temperature (4 K). Scientists around the world use LabVIEW and National Instruments products to design and control instruments. Typical Use case of LabVIEW in research labs. What were the biggest problems encountered?: Low power supply capability, coupling between Ch1 and Ch2 of the oscilloscope, it has bandwidth limitations and voltage input limitation, the device gets disconnected often(probably faulty cable) What other parts do you consider comparable to this product?: ADALM1000,SainSmart DDS140,Hantek iDSO 1070A,Link Instruments MSO-28 RoadTest: Analog Discovery 2 + LabView Home Bundleĭid you receive all parts the manufacturer stated would be included in the package?: True
