Digilent Analog Discovery 2

The Swiss Army Knife of Test Equipment

Digilent Analog Discovery 2
Whether you're a student learning electronics 101, setting up a new test bench or want to upgrade some of your equipment, the powerful Analog Discovery 2, developed in partnership with Analog Devices®, is an amazing multi-function instrument that will allow you to generate, measure, visualize, capture and control diverse signal circuits of all kinds.

It's small enough to fit in your pocket but is more than capable enough to replace a table full of lab equipment benefitting all engineering students, hobbyists, lab and repair technicians and electronics aficionados. Now you'll have the opportunity to work with analog and digital circuits in the lab or in the field.

You can do a lot with a digital multimeter, but once you get into debugging and troubleshooting circuits or you need to analyze faster or pulsed signals, an oscilloscope is an indispensable tool. The Analog Discovery 2 combines a 100MS/s USB oscilloscope, waveform generator, logic analyzer, low-voltage programmable power supply and more into a device measuring only 3.2" square by 0.95" high. It will work with your Mac, Windows or Linux-based machine.

What can the Analog Discover 2 do?

Data Logger- Data loggers do what their name suggests; they log or record data over relatively long periods of time. If you need to record something over a short interval, you may consider the oscilloscope function. Use the WaveForms software to record data.

Waveform Generator - Use waveforms to test circuits by generating specific signals to feed into the circuit you are testing. An arbitrary waveform generator(AWG) will output whatever you define, but you can also make the function generator output sine, square and other predefined signals. This feature alone can save you hundreds or even thousands of dollars!

Oscilloscope- Graphically display signals like voltage and current over time. The Analog Discovery 2 eliminates bulky and expensive equipment with its compact, lightweight and affordable design. It has 2 channel, 1M?, ±25V voltage range, differential, 14-bit resolution, 100 MS/s sample rate, and 30+ MHz bandwidth. Be sure to use with the BNC Adapter board to utilize all of the functions.

Impedance Analyzer- Thought of abstractly as the resistance of a circuit, the impedance is the total opposite force to the flow of electronics through a system. Use the WafeForms software to provide information about the load under test form the impedance, admittance, inductance, capacitance, phase and quality factor of the system. If you design filters with narrow specifications matching impedances.

Logic Analyzer - Record and evaluate digital communication signals. Similar to an O-scope except the data is processed and displayed with supplementary data that is calculated by the software to help with this evaluation. Use WaveForms software to record and translate most types of digital communication signals.

Network Analyzer - Discover how a circuit will respond with certain inputs. Components like capacitors and inductors interact with and change the input signal to create the output signal, and you'll use the WaveForms software to get an idea how circuits respond to various types of inputs.

Protocol Analyzer - Connect a piece of hardware, power it, and read or write to it. Use the logic analyzer to discover if communication between components is working, but once you've isolated the malfunctioning component, the protocol analyzer is the tool to use. You can also use the pattern generator to test the communication protocols.

Spectrum Analyzer - This easy to use tool takes somewhat complex measurements and make it easier to interpret what your electronic components are doing. Electrical noise is common in nearly all electronic systems, and many can be affected by external interference. The spectrum analyzer tool can help you identify internal and external concerns to help you work toward more efficient performance.

Pattern Generator - Generate a defined pattern of digital logic high/low signals or pulses. Use the 16 channels to generate whatever digital pattern from a single signal to a full 16-bit bus.

Voltmeter - A common feature of a digital multimeter (DMM) that is also available as a tool in the WaveForms software to efficiently and directly measure the voltage across a component.

Measure Current - The Analog Discovery 2 can't directly measure the current flowing through a circuit, but it can be calculated and viewed easily within the WaveForms software.

Power Supplies- Power supplies are must-haves for a test bench but can be bulky items. The built-in programmable power supply has two channels supporting an output voltage from 0 to 5V or from 0 to -5V. When connected to USB, expect only 250mW maximum power per channel. If you equip an external supply, the maximum power per channel rises to 2.1W.

Static I/O - Static input/output pins are used for sensing or generating change-of-state events. Utilize the 16-channel I/O for this analysis.

External Triggering - The built-in tools for 2-channel oscilloscope, power supplies, waveform generators, logic analyzers and more to generate and measure digital and analog signals can be triggered by an external source. There are two bidirectional triggers.

BNC Adapter (add-on) - Utilize this add-on board to enable the use of standard BNC terminated test leads and test probes to gain improved attenuation for the oscilloscope tool within WaveForms software.
