WiPry-Power's Features and Benefits
Here are a few of WiPry Power’s prominent features and a description to help you get started.
SMB Coaxial Connector You can use the included 2.4 GHz antenna for radiated power measurements, or use cables to make conducted power measurements. Learn about Oscium’s conducted measurement accessory pack here.
30-Pin iOS Connector You connect WiPry-Power to your iOS device with this connector. Your iPhone, iPod or iPad powers WiPry through this connector so there’s no power cord to carry or extra batteries to keep charged. WiPry-Power passes the digitized power measurements to your iPhone through this connector, integrating signal and power into a single connection.
Touch Screen Oscium wrote the WiPry user interface taking full advantage to the iOS device touch screen. You have
all the menus and measurement controls available at the touch of a finger. You can scroll and zoom the measurement window by simply squeezing together or spreading apart your two fingers on the screen. Of course, if you’ve ever used an iPhone, iPod or iPad to listen to music or check your email then you’re already an expert with the touch screen.
WiPry App from iTunes Start making RF power measurements when you open the WiPry App with your iPhone, iPod, or iPad. The application is free at iTunes.com or the App Store and loads in 30 seconds, or less. You can use WiPry’s demo mode to try out the user interface and measurement capabilities on simulated WIFI, DECT, and DSS signals.
Getting Started Using WiPry-Power
Unpacking the box
WiPry-Power arrives handsomely packaged with everything you need to get started right away. You’ll find the WiPry-Power device and the 2.4 GHz SMB antenna when you open the box, resting securely in the professionally designed electro-static safe foam packaging. Your WiPry Power comes with Oscium’s Quickstart Guide reference card with step-by-step instructions for getting started. Be sure to read the warning about WiPry-Power’s maximum input power level.
Downloading and using WiPry
You can download Oscium’s free WiPry app from iTunes on your computer or from the App Store if you are using an iPhone, iPod, or iPad. WiPry works will all the iOS devices listed that run iOS 4 or later, regardless of which device generation you are using. Run WiPry’s demo mode and analyze simulated WiFi, DECT, and DSSS protocol signals. Oscium enables the vertical and horizontal cursor measurements in demo mode so you can become familiar with the capabilities without WiPry Power installed.
Connect WiPry Power to Start Measuring RF Power
Use your iPhone, iPod, or iPad to make RF power measurements with the WiPry app installed and WiPry-Power connected. You can set the trigger level, vertical position and scroll and zoom along the time scale just like using an oscilloscope. Set the vertical and horizontal cursors on the screen to collect information about the signals you are analyzing. WiPry lets you capture a reference trace, store it in memory, and compare it to active measurements with just a few taps on the screen. Choose from WiPry’s built-in measurement statistics, like Peak, Average, Duty Cycle, and Pulse Width, and have up to 6 displayed at any time. WiPry allows you to save measurement settings in setup configurations and capture your results in data logs. You can transfer your measurements off your iOS device by emailing screenshots or csv formatted text files.

Most power meters can only provide you with an average power reading. Very few are capable of measuring peak power. Additionally, WiPry-Power will allow you to visually look at protocol level transmissions, duty cycle, and more. WiPry-Power is an invaluable tool that will help make RF design easier than ever.
The capabilities of WiPry-Power are equivalent to some of the most expensive power meters on the market. We have priced WiPry-Power aggressively because we have found that it is extremely useful for 2.4GHz design, and we want everyone to have acces to this tool.
Double tapping on the screen provides additional detail related to the metrics both for the X and the Y axis.
Along the X axis, major divisions are identified in the bottom right corner. It will look something like this, T: 4μs/div. This means that each major hashmark (or line) along the vertical plane is 4μs from the next one. In demo mode, it is only possible to view activity at 4μs/div; it's not possible to zoom in and out in demo mode. However, once hardware has been plugged in, the available timescale is actually 2 μs/div to 1 s/div.
Along the Y axis, the major divisions are identified in the bottom left corner. It will look something like this, A: 7.19dBm/div. This means that each major hashmark (or line) along the horizontal plane is 7.19dBm from the next one.
You will be measuring radiated power versus conducted power. And this measurement will be dependent on the antenna, orientation, environmental factors, and more. For the most accurate power measurements, we recommend using the conducted measurement kit (because it gives you the ability to actually connect to the RF source). Please note that if you are measuring powers greater than 20dBm, you will need to add external attenuation.
Yes. Touch and hold the pause / play menu icon and it will change into single shot mode. After the mode has been changed, tap the single shot icon and the next event will be captured and held. To go back to pause / play mode, touch and hold the single shot icon.
20dBm is the max. If you need to make higher power measurements, please make sure that you use external attenuation to bring the power level below 20dBm.
If you're using an iPhone / iPod touch, you can use WiPry-Power continuously for approximately five hours. If you're using an iPad, you can use WiPry-Power continuously for approximately eight hours.
Please understand that these estimates are just that, estimates. Your results may vary based on your background usage level (WiFi, email push, other apps, etc).
