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.

Getting Started

Welcome to the 1002 user guide! In order to get started, make sure you have the following hardware on hand:

  • 1002 PhidgetAnalog 4-Output
  • USB cable and computer
  • something to use with the 1002 (multimeter, oscilloscope, device with voltage input, etc.)

Next, you will need to connect the pieces:

  1. Connect the output of the 1002 to your device. Note the polarity on the underside of the 1002.
  2. Connect the 1002 to your computer using the USB cable.

Now that you have everything together, let's start using the 1002!

Using the 1002

Phidget Control Panel

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.

First Look

After plugging the 1002 into your computer and opening the Phidget Control Panel, you will see something like this:

1002 Panel.jpg

The Phidget Control Panel will list all connected Phidgets and associated objects, as well as the following information:

  • Serial number: allows you to differentiate between similar Phidgets.
  • Channel: allows you to differentiate between similar objects on a Phidget.
  • Version number: corresponds to the firmware version your Phidget is running. If your Phidget is listed in red, your firmware is out of date. Update the firmware by double-clicking the entry.

The Phidget Control Panel can also be used to test your device. Double-clicking on an object will open an example.

Voltage Output

Double-click on the Voltage Output object in order to run the example:

1002 VoltageOutput Example.jpg

General information about the selected object will be displayed at the top of the window. You can also experiment with the following functionality:

  • Set the output voltage by dragging the Voltage slider.
  • Enable/disable the output voltage by toggling the Enable button.

Technical Details


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 reliable results, don’t approach this limit, as it will vary from channel to channel.
  • For maximum accuracy, limit the current to 5mA.
  • If more than ±20mA of current is drawn, the device goes into a constant current supply mode. When this happens, the current will be held constant at it’s maximum value, and the output voltage will depend on the value of the load that the device is trying to drive.
  • If your application requires a larger current source / sink, the 1002 can be used as an input to a larger external amplifier circuit.
  • All the power is supplied by the USB bus.

USB Cables

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.
