The HDAVO is an optional mixed-signal module that can provide source and capture test capabilities with Arbitrary Waveform Generator (AWG) and Digi t i zer (DGT) functions when integrated into the 3680 SoC test system. The module has 8 AWG and 8 digitizers on an instrument board which can be allocated to any universal slot in the 3680 SoC system. With a maximum of 120MHz instrument bandwidth and density, it can meet the performance required by a wide range of device types. Building either in audio or video band on each channel, the module can accomplish multisite testing with lower cost.

The HDAVO achieves the I/Q phase and amplitude matching with better 25ps channel to channel skew through a dedicate external calibration board. This enables the system to test a wide range of I/Q modulator standards such as 802.11a/b/g/n wireless LAN and cellular baseband processor.

The CRISPro software environment provides a power ful tool for the user to setup the HDAVO via a Graphic User Interface (GUI). The coding based with user friendly environment can produce test programs quickly and easily to implement concurrent functions for complex and multi-function SoC device with lower cost of test (CoT) requirement.
