Warranty

Limited warranty is provided against manufacturing defects only.

Intended usage

The device is only to be used with a genuine Analog Discovery 2™ hardware, WaveForms™ software and accompanying WaveForms™ workspace.

Up-to-date documentation

Links to the up-to-date documentation will be provided at the product page: https://knack.supply/product/ad2ct/

Documentation

Download the “.dwf3work” workspace file from https://github.com/knack-supply/ad2-curve-tracer.

Open it with WaveForms™ software.

Switch to Tabbed Interface in WaveForms™: Settings → Options → General → Instrument windows: Tabbed.

Plug in the add-on into Analog Discovery 2™ as shown:

Add-on board with AD2

Insert the device under test, according to pinout shown in the next section.

Click “Play” button on the “Script” tab in WaveForms.

Switch to the “Scope” tab.

Waveforms interface

Pinout

The IC socket has 2 rows: one for diodes and one for transistors.

Pinout

Diodes

Use the row closest to the board-to-board connection header. The pin closer to the centre of the board is anode, the rest are cathode.

Transistors

Use the row furthest from the board-to-board connection header and closest to the edge of the board.

From the middle of the board to the edge:

  1. Collector / Drain
  2. Base / Gate
  3. Emitter / Source
  4. Collector / Drain
  5. Base / Gate
  6. Emitter / Source
  7. Collector / Drain

Compliance

RoHS

All components and substances used in manufacturing of this product are RoHS compliant.

Safety

The device doesn’t expose voltage higher than it’s host device, Analog Discovery 2, can provide. Usually it’s 10V between -5V and +5V rails, referenced to AD2’s device ground.

Current drive capability is limited to that of AD2’s adjustable dual-rail power supply and is further limited by design of the device itself to 60mA.

EMC

The device doesn’t radiate EM intentionally.

Unintended oscillations in the device could only theoretically occur at frequencies below 1.1MHz (typ.), there are no traces on the PCB which could act as transmitting antennae at those frequencies.
