The Current Sense Transformer In past blogs we've discussed the current measurement features of the ADALM1000 (SMU). The ALM1000's SMU channels can measure DC currents from -200mA to +200mA. Because of the 100 KSPS sampling rate it can actually measu...

All the connections to the ADALM2000 personal instrument hardware are made though the 30 pin male header (0.1 inch centers) connector. This is a very common, generic connector and is simple to attach wires to as with the various female to female cabl...

The objective of this tutorial is to use the Pattern Generator and Logic Analyzer instruments provided by the ADALM2000 (M2K) board and the Scopy software toolset to visualize UART (Universal Asynchronous Receiver/Transmitter) transactions between t...

In this tutorial we will use ADALM2000 (M2K) board and the Logic Analyzer instrument provided by the Scopy software toolset to visualize I2C (Inter-Integrated Circuit) transactions between two devices. The ADT7420 PMOD Temperature Demo project will ...

The objective of this tutorial is to use the Logic Analyzer instrument provided by the ADALM2000 (M2K) board and the Scopy software toolset to visualize SPI (Serial Peripheral Interface) transactions between two devices. The Total Dissolved Solids ...

The best transistors to keep in your stock of parts When you need transistors for a project there are a multitude of choices. This can make answering the question “What transistor should I use?” potentially very confusing. Fear not, befor...

Using Signals from the Headphone Output Active Learning Modules (M1k , M2k) The objective of this Blog entry is to show how to connect the audio output from the headphone jack on laptop computers, tablets or smart phones to be used in conjunction wit...

Measuring Seismic waves with ADALM1000 and a Geophone Commercial systems used for seismic exploration usually require expensive analog instrumentation. In this Blog entry, a low cost vertical geophone is connected directly to the analog input channe...

Which Multi-meter to add to my tool kit? From the simple interconnection of a few resistors to a large complicated circuit, every design needs to be tested for its electrical properties. The two channel scope and function generator software instrumen...

Extra power supplies for Active Learning Modules (M2k , M1k) We have over the years gotten many questions with regard to the limited current and voltages available from the built in user power supplies provided by the Active Learning Modules ADALM100...

A Classic phase measurement, The Lissajous pattern All periodic signals can be described in terms of amplitude and phase. We all learn that in basic circuit theory classes. You surely have needed to calculate a signal's phase change when it passes t...

New Feature in ALICE Adds Input Divider Frequency Compensation In this blog installment we are going to talk about a problematic limitation of the ADALM1000. To keep production costs of the board low, certain trade-offs were made. One was to foreg...

Measuring very small resistances with ADALM1000 part 2 This blog installment continues the discussion on making a Milliohm meter using the ADALM1000 and AD8210 current shunt monitor IC. Using the solder-less breadboard to connect to the AD8210 can...

The objectives that we want to accomplish in this article are to examine the frequency spectrum of signals and emphasize filtering by a second-order filter circuit using the ADALM2000 Active Learning Module connected to a host via Scopy applic...

ASEE Paper on Personal Instrumentation and the ADALM1000 In this paper from the June annual meeting of the ASEE, "Requirements for the Effective Application of Personal Instrumentation in ECE Undergraduate Courses", faculty from a number of univer...

Measure very small resistances by building your own Milliohm-meter The lowest resistance range on a typical three and a half digit DMM is 200 ohms with a resolution of 0.1 ohms. A much more expensive high end dedicated bench milliohm meter will su...

One of the primary uses of Amplitude Modulation is in aiding the transmission of information. Let us suppose we are in a room full of students, and the students in the back of the classroom cannot hear the teacher. He can increase his volume and s...

Combining ALICE Scope traces in LTSpice Simulations The ADALM1000 and ALICE 1.2 Desktop is a multi-purpose and incredibly useful set of measurement tools for testing electronics projects and experiments. Circuit simulators like LTSpice, and others...

Combining LTSpice Simulations with ALICE Scope traces Circuit simulators like LTSpice, and others, are useful tools for testing out electronic circuit experiments before actually constructing the circuit. The ADALM1000 and ALICE 1.2 Desktop is a m...

The ALICE Impedance Analyzer ALICE 1.1 Desktop is a multi-purpose and incredibly useful tool for working on electronics projects and experiments. But with all its capabilities it can be a little intimidating to get comfortable using all of the too...

How do you know if your copy of ALICE is up to date? As we develop courseware and lab activities for the ADALM1000 we often discover new ways to improve ALICE. New versions are put up on the ADI Wiki site for download frequently. Sometimes they co...

ETS and increasing the Bandwidth of the ADALM1000 In two previous blogs we discussed how to use equivalent time sampling (ETS) techniques in the software to display higher frequency signals with the ALM1000 hardware. In this blog we will talk abou...

More on Equivalent Time Sampling with the ADALM1000 As was discussed in a previous blog, a new version of the ALICE 1.1 desktop software suite for ADALM1000 (as of 7-5-2017) now includes an option that implements a form of equivalent time sampling...
