Digilent BNC Adapter Board

Added to your shopping cart

The Digilent BNC Adapter Board is a simple add-on board intended to be used with the Digilent Analog Discovery 2, which allows you to use standard BNC-terminated test leads and probes with your pocket-sized oscilloscope. The adapter board provides BNC terminations to each of the two oscilloscope channels and enables you to AC couple or DC couple signals to the oscilloscope in the Analog Discovery.

Each channel of the oscilloscope can be selected as AC or DC, coupled by adjusting the jumper that is located behind that channel’s BNC input connector. In addition, the two AWG channels are equipped with BNC terminations, and each channel can have either the 50-ohm or the 0-ohm termination selected. This enables the user to match the Analog Discovery’s output impedance with standard 50-ohm test leads or to be directly tied to the lead. Additionally, the adapter board takes the oscilloscope bandwidth from 9 MHz (wire harness) to 30 MHz on the Digilent Analog Discovery 2.

  • Allows the use of standard BNC-terminated test leads and probes on your Analog Discovery
  • Selectable AC and DC coupling to oscilloscope probes
  • Selectable 50-ohm or 0-ohm output impedance on arbitrary waveform generator (AWG) channels
  • With the Discovery BNC, the differential scope inputs of the Analog Discovery become single-ended with the negative input connected to the ground

Digilent BNC Adapter Board Product Help and Resources

Core Skill: DIY

Whether it's for assembling a kit, hacking an enclosure, or creating your own parts; the DIY skill is all about knowing how to use tools and the techniques associated with them.

1 DIY

Skill Level: Noob - Basic assembly is required. You may need to provide your own basic tools like a screwdriver, hammer or scissors. Power tools or custom parts are not required. Instructions will be included and easy to follow. Sewing may be required, but only with included patterns.

Core Skill: Electrical Prototyping

If it requires power, you need to know how much, what all the pins do, and how to hook it up. You may need to reference datasheets, schematics, and know the ins and outs of electronics.

2 Electrical Prototyping

Skill Level: Rookie - You may be required to know a bit more about the component, such as orientation, or how to hook it up, in addition to power requirements. You will need to understand polarized components.

Customer Comments

  • I have the original Analog Discovery. The header configuration looks the same. Will this work with mine?

    • Yup! The BNC Adapter Board is compatible with both the Analog Discovery and the Analog Discovery 2.
