Saelig Company, Pittsford, NY, has introduced WiPry-Combo, a dynamic power meter and spectrum analyzer accessory for the iPad, iPod Touch, and iPhone. It turns an iOS device into an ultra-portable spectrum analyzer and dynamic power meter. WiPry-Combo brings RF power measurements to a graphical interface to show RF waveforms like an oscilloscope. Instead of showing voltage, RF amplitude is displayed on an iOS portable device. Data is collected at up to 12 MSa/s, allowing analysis and verification of the smallest protocol level on/off times. WiPry-Combo offers datalogging in csv format, while screenshot results can be instantly e-mailed via the iOS host phone. In Spectrum Analyzer mode, it identifies interference or open channels in the 2.4-GHz ISM band, or identifies unauthorized WiFi access points. In Dynamic Power Meter mode, the device becomes a 100-MHz to 2.7-GHz RF power meter accessory that graphically displays RF power levels.
