LitePoint Corp. has unveiled what it touts as the first device test solution specifically designed for Multicom devices—single devices, such as smart phones and mobile Internet devices, containing multiple radios and wireless connectivity standards.

The IQ2010 connectivity test system is designed to keep test times and costs low without compromising Multicom device test accuracy. Using a variety of RF ports and user-selected (licensed) communications standards, the IQ2010 can be configured to suit a device's set of wireless connectivity features.

Combined with concurrent testing and sequence-based testing (SBT), an IQ2010 system can reduce test times significantly. For example, Wi-Fi transmit tests can be reduced to one-sixth the typical test time, and Wi-Fi receive tests can be cut to one-fourth.

The IQ2010 test system uses multiple hardware blocks to provide concurrent test capabilities for GPS and FM wireless standards in parallel with Wi-Fi, WiMAX, Bluetooth and NFC standards. Multiple vector signal generator sections provide transmit signals for FM, GPS, Wi-Fi, Bluetooth, WiMAX and NFC transmit testing. Multiple vector signal analyser sections provide matching capabilities for receive testing.

The new test system includes software libraries specific to each communication standard (Wi-Fi 802.11 a/b/g/n; Bluetooth 1.0, 2.0, 2.1; GPS, FM TX/RX, WiMAX 802.16d/e; and NFC). Users can select a variety of signal creation and analysis routines using either the included GUI or a C++ API. Data captured by IQ2010 is sent to a controlling PC via USB 2.0 for processing. The C++ API supports all GUI functions making it easy to create automated test programs for manufacturing or design-characterisation testing.

The system also features four RF device connection ports—one each dedicated to GPS and FM, and two common ports (RF1 and RF2) used for connecting to Wi-Fi, WiMAX, and Bluetooth sub-systems under test.

The IQ2010 test system addresses RF calibration, verification and testing needs for all supported connectivity radios. A single insertion, using a single connection, can be used to test multiple radios. The variety of RF ports supports cabling flexibility. Users can test single communications modalities, or test multiple-radio device modalities in concert. Combined with a cellular test system, the IQ2010 supports complete smart phone test coverage in one test station.
