Waveform Analog Discovery 2 Portable Form Factor
It is not intended to provide enough information to enable complete duplication of the Analog Discovery 2, or to allow users to design custom configurations for programmable parts in the design.Analog Discovery 2 is the next generation of the very popular Analog Discovery. This document describes the Analog Discovery 2's circuits, with the intent of providing a better understanding of its electrical functions, operations, and a more detailed description of the hardware’s features and limitations. Meeting all of these requirements proved challenging however, the task ultimately generated some new and innovative circuits. Its features and specifications, as well as the additional requirements of operating from USB or external power, maintaining the small and portable form factor, the robustness to withstand student use in a variety of environments, and low-cost are based directly on feedback that was obtained from numerous professors from several universities. The SDK for the Digilent Analog Discovery 2 comes in the form of a.The Analog Discovery 2 was designed for students in typical university-based circuits and electronics classes. Accessing the AD2 SDK from Java.
The core of the Analog Discovery 2 is the Xilinx® Spartan®-6 FPGA (specifically, the XC6SLX16-1L device). Furthermore, for distortion-free measurements, the common mode and differential voltages need to meet specifications.Important Note: Pinout Diagram 1.1 Architectural Overview and Block DiagramAnalog Discovery 2's high-level block diagram is presented in Fig. The circuit under test might also be connected to earth or possibly floating.For safety reasons, it is the user’s responsibility to understand the powering and grounding scheme, and to make sure that there is a common GND reference between the Analog Discovery Studio 2 and the circuit under test, and that the common mode and differential voltages do not exceed specifications. – which might also be grounded) the Analog Discovery Pro's GND reference might be connected to the whole GND system and ultimately to the power network protection (earth ground). Depending on the PC powering scheme, and other PC connections (Ethernet, audio, etc.
Waveform Analog Discovery 2 Software Works With
Referring to the block diagram in Fig. Analog voltages are prefixed with a “V” (for voltage), and suffixes and indexes are used in various ways: to specify the location in the signal path (IN, MUX, BUF, ADC, etc.) to indicate the related instrument (SC, AWG, etc.) to indicate the channel (1 or 2) and to indicate the type of signal (P, N, or diff). Signal and equations also use certain naming conventions. Signals in the Analog Output block, also called AWG, use “AWG” indexes, and signals in the Digital block use a D index – all of the instruments offered by the Discovery 2 and WaveForms use the circuits in these three blocks. The WaveForms software works with the FPGA to control all the functional blocks of the Analog Discovery 2, including setting parameters, acquiring data, and transferring and storing data.Signals in the Analog Input block, also called the Scope, use “SC” indexes to indicate they are related to the scope block. Once programmed, the FPGA inside the Discovery communicates with the PC-based WaveForms application via a USB 2.0 connection.
As examples, in equation \ref$ coordinates.To be visible on the scope screen and not distorted, a signal should be included in all the solid line polygons of a figure ( linear range = geometrical intersection of the surfaces).Only the differential input voltage is shown on the scope screen. Indexes are omitted where not relevant. For example, the Scope Input Divider and Gain Selection schematic is only shown for channel 1 since the schematic for channel 2 is identical. The WaveForms software uses these parameters to correct the acquired data and the generated signalsIn the sections that follow, schematics are not shown separately for identical blocks. Instead, a calibration operation is performed at manufacturing (or by the user), and parameters are stored in memory. Except for the “Probe Calibration” trimmers in the scope Input divider, the Analog Discovery 2 includes no analog calibration circuitry.
The graphical representation will be clamped. A signal overpassing the linear range will be distorted on the scope screen, i.e.
