In the picture above, Oscium’s iMSO-104 and an iPad mini display the pulsed output of an Arduino board’s Pulse Width Modulation (PWM) output. In the foreground, an LED is illuminated by the pulses from the Arduino board. Making an LED light up is a simple use for this circuit, but often it’s also...

Have you ever wondered how music professionals modulate and combine audio signals? They use something called an audio mixer, which takes input from two channels and combines them in a proportion that the user can set. Here's a fun electronics project for beginners that shows you how to build an...

Part of the fun in electronics is taking stuff apart to see how things work. Sometimes this might be as involved as disassembling a smartphone or other high tech device, or as simple as stripping the insulation off of conductors in a cable assembly to get access for probing. In this picture, a USB...

Pictured above is Oscium’s iMSO-104 handheld oscilloscope measuring the waveform of a Mass Air Flow (MAF) sensor for General Motors Vortec V8 engine. In modern post 1990’s vehicles, MAF sensors monitor the flow of air through the engine’s intake and provide real time information to the vehicle’s...

In this picture, the pulsed RF output of a remote control to a garage door opener is measured with Oscium’s WiPry-Combo and displayed using an iPhone. First, confirm that the device is in power meter mode (versus spectrum mode). The time scale is set to display two pulses – the minimum necessary to...

OKLAHOMA CITY, OK –June 25, 2013--Oscium creates test equipment that utilizes the intuitive features and touchscreen technology of mobile devices like the iPad and iPhone. Founded by brothers Matt and Bryan Lee in January of 2010, Oscium existed for an entire year before releasing its first product...

The car-mounted antenna in this picture is a SIRIUS XM Satellite Radio antenna for receiving music and news radio broadcasts from satellites orbiting around the earth. The simplified block diagram shows how to use Oscium’s WiPry-Combo Peak Power Meter to investigate the signals from radio, GPS, or...

This picture shows the transient voltage response to a step function as the stimulus to the device. Oscium’s handheld oscilloscope and iOS-based software simplifies the process for measuring this and other parameters of interest. There are several parameters worth mentioning that are used to...

In this picture, the Oscium iMSO-104 handheld oscilloscope and iPad 2 are displaying the waveforms of an oscillator circuit that’s part of an infrared transmitter. The three traces plotted on the oscilloscope screen represent the time varying voltages at critical points in the oscillator circuit...

This picture depicts the settling time of a waveform’s response to a step function stimulus at the input. Conventional settling time is defined as the elapsed time from the application of a step at the input to the time at which the device output enters and remains within a specified error band...
