In the picture above, Oscium’s iMSO-104 oscilloscope is measuring the output waveform of an infrared receiver (IR Rx). The iPad and iMSO are functioning as the oscilloscope for measuring the receiver’s output signal as the relative alignment between transmitter and receiver varies. There are two...

This picture shows a conducted measurement test setup using iPad Mini and WiPry-Combo . The extension cord between iPad Mini and WiPry-Combo affords users much needed flexibility in positioning the DUT with respect to the measurement instruments. In this case, the iPad Mini can be placed in a safe...

Tonight is movie night and it’s time to make the microwave popcorn – but don’t forget the butter and salt! While the microwave oven cooks a bag of popcorn, the video streaming from the local Wi-Fi stalls, and then after some delay Netflix pops up an error message saying the network link went away...

Frequently asked questions about WiPry-Pro Combo. How do I use WiPry to optimize my WiFi network settings? Spectrum mode allows you to view which frequencies in the spectrum are already in use or have a high noise floor. Selecting a channel with a low reading will yield increased throughput and...

Here are some frequently asked questions for LogiScope: Does LogiScope work with the Lightning Adapter? Yes. The official Apple Lightning adapter is compatible. Is it possible to perform a single-shot waveform capture? Yes. Touch and hold pause or play (in the bottom right corner) until it changes...

Frequently asked questions about WiPry 2500x, WiPry 790x, WiPry 340x, WiPry 5x, WiPry-Pro, & WiPry-Pro Combo. General Questions How do I use WiPry to optimize my WiFi network settings? Spectrum mode allows you to view which frequencies in the spectrum are already in use or have a high noise...

Frequently asked questions for iMSO-204x , iMSO-204L, iMSO-204 & iMSO-104. General Questions Can I measure AC voltage and in what voltage range? Yes, you can measure either AC or DC voltage on the analog channel. The maximum voltages are -8v to +13v in 1x mode and -40v to +40v in 10x mode. What...

In the March 2013 issue of Electronic Design, Maxim Integrated engineer Bill Laumeister writes about the increasing role of robots in our everyday life. True to Moore’s Law predictions, continuing miniaturization and reduced cost of individual transistors allows for microprocessors that are more...

The figure above contains a series of charts showing the equivalent DC voltage from a Pulse Width Modulation (PWM) signal over a period of time. There are subcharts showing the measured PWM signal at points in time indicated in the main chart’s saw tooth shaped waveform. I created these charts from...

The figure above is a schematic diagram of a Pulse Width Modulation (PWM) signal driving an LED with an handheld oscilloscope and voltmeter monitoring the LED’s voltage. In this post and the next we will look at how the pulsed voltage resembles a DC voltage to a load, and use an Excel spreadsheet,...
