Note: The 1002_0B is identical to the 1002_0, except that you have the option of whether you want to include the USB cable.
The PhidgetAnalog 4-Output Produces a voltage over -10V to +10V at a maximum of ±20mA. If this current is exceeded an error will be thrown to notify that the voltage may have dropped below the setpoint. The voltage is produced with 12 bit resolution (4.8mV).
The board is not isolated and all 4 channels share a common ground.
All the power is supplied by via USB.
* The maximum output frequency is dependent on the speed of your system.

Welcome to the 1002 user guide! In order to get started, make sure you have the following hardware on hand:
Next, you will need to connect the pieces:
Now that you have everything together, let's start using the 1002!
In order to demonstrate the functionality of the 1002, the Phidget Control Panel running on a Windows machine will be used.
The Phidget Control Panel is available for use on both macOS and Windows machines. If you would like to follow along, first take a look at the getting started guide for your operating system:
Linux users can follow the getting started with Linux guide and continue reading here for more information about the 1002.
After plugging the 1002 into your computer and opening the Phidget Control Panel, you will see something like this:
The Phidget Control Panel will list all connected Phidgets and associated objects, as well as the following information:
The Phidget Control Panel can also be used to test your device. Double-clicking on an object will open an example.
Double-click on the Voltage Output object in order to run the example:
General information about the selected object will be displayed at the top of the window. You can also experiment with the following functionality:
The terminal blocks on this board are labelled on the underside to save space:
The 1002 is not isolated. All four channels use the same ground.
The 1002 will limit the available current per channel at ±20mA.
For more information on analog outputs, see the Analog Output Primer.
You can protect your board from dust and debris by purchasing an enclosure. An enclosure will also prevent unintentional shorts caused by objects touching the pins on the bottom of the board or any terminal screws.
Use a USB cable to connect this Phidget to your computer. We have a number of different lengths available, although the maximum length of a USB cable is 5 meters due to limitations in the timing protocol. For longer distances, we recommend that you use a Single Board Computer to control the Phidget remotely.
