-This adapter should be connected to the Digital Discovery's "HIGH SPEED INPUTS" pin group with the Ground symbols (downward facing arrows) pointing to the bottom of the device. While the adapter can be connected "upside down", doing so will result in the pin names shown in the [[https://reference.digilentinc.com/reference/instrumentation/digital-discovery/reference-manual#accessories|Digital Discovery Reference Manual]] not matching the actual pin names. Note that these pins cannot be used for digital output.+This adapter should be connected to the Digital Discovery's "HIGH SPEED INPUTS" pin group with the Ground symbols (downward facing arrows) pointing to the bottom of the device.

 If desired, one of these input pins can be used in this guide, along with any of the Digital Discovery's output-capable pins. Connect one of the provided black/red differential probes to the High Speed Adapter. Make sure that the black cable is connected to the side with the ground arrow. The black cable should be connected to the ground of the device under test (in this case, the Digital Discovery's ground). The red cable (the positive side of the p/n differential pair) should be connected to the chosen digital output. If desired, one of these input pins can be used in this guide, along with any of the Digital Discovery's output-capable pins.

-To use the //Logic Analyzer//, some signal/s must be applied to the digital input/s used. This guide uses the device's //Pattern Generator// instrument to apply a signal to the chosen digital input pin through the chosen digital output pin.

-The //Logic Analyzer// instrument can be used with other WaveForms instruments. Using multiple instuments at the same time is helpful in a wide variety of situations. One example would be to use the //Protocol Analyzer// to configure a device under test, the //Pattern Generator// or //Protocol Analyzer// to stimulate the device, and capturing the result in the //Logic Analyzer//, all at the same time. More information on how instruments can be operated together can be found in the [[reference:test-and-measurement:guides:waveforms-cross-triggers]] guide.+The //Logic Analyzer// instrument can be used with other WaveForms instruments.

 It should be noted that while multiple instruments can use any Digital Input pin, and those pins can be used as Digital Outputs, no more than one instrument can control a Digital Output pin at a time. WaveForms accounts for this by disabling instruments using a shared output, or by displaying a message stating that a shared output is currently used by a different instrument. It should be noted that while multiple instruments can use any Digital Input pin, and those pins can be used as Digital Outputs, no more than one instrument can control a Digital Output pin at a time.
