To get started, you will need to connect the PSLab device, run the software, and configure the circuit.
There are PSLab applications for Android as well as Windows, macOS, and Linux on PCs.
Connecting the PSLab¶
Connecting to a PC requires a USB cable, or an OTG “On the Go” cable for an Android mobile device. The PSLab has a “micro-USB” connector, and the other end will be typically a USB-A, USB-C, or micro-USB connector, depending on the client device.
Alternatively, Bluetooth operation allows connection to devices without a physical cable. In addition to more flexibility, this also provides isolation between the PSLab and the client device.
Configuring the first circuit¶
WARNING: Do not use PSLab with high voltage circuits, in hazardous environments, or without appropriate supervision!
Before you start, keep the following in mind:
Short circuits can damage the PSLab, connected equipment, and potentially cause a fire.
PSLab when used connected to a computer or some power supplies has an earth ground. This may create a potentially dangerous voltage differential and affect some modes of operation. This needs to be taken into consideration when working with electronic circuits. The safest mode of operation is on battery, connected via Bluetooth.
To get started, we will use a very simple circuit where the output of one PSLab instrument is connected to the input of another instrument on the same device. This simple “Hello World” circuit allows us to verify that the software and hardware are working properly.
Using a short dupont wire, connect Voltage 1 (PV1) directly to Channel 1 (CH1) Hint: For most circuits you would also connect a ground wire. There is no need to connect ground in this case, as it is connected internally on the PSLab.
Connect the appropriate USB cable from the PSLab to your device
Open the PSLab application
Select Power Source
Change PV1 to 3.3V
Click the back arrow in the top left corner of the screen
In the Voltage section, click CH1
Observe the voltage output. It should read 3.3V
Click the back arrow, and repeat steps 4 through 9 using a different voltage
Congratulations, you just verified the software and hardware are working!
If something went wrong, verify the cables are correctly connected, unplug and replug in the PSLab, and restart the application before trying again. For any further help, feel free to ask via Gitter.
