Protocol Generators and Analyzers
| Protocol Generators and Analyzers

This BIT-3000 DSGA is designed as a complement to high-speed instruments like AWGs or BERTs.
MIPI M-PHY and D-PHY source or receiver test often require complex sequences which interleave high-speed (HS) and low-power (LP) data, which is complicated to impossible to implement only with dedicated high-speed equipment. The DSGA fills this gap by generating the LP data, while at the same time triggering on and recording the PWM-encoded response from the DUT. The primary application is to bring the DUT into test mode, and to read the frame- and error counters from the DUT.
The Test Automation software ValiFrame / N5990A enables fully automated control over the BIT-3000 DSGA. The user can use the Frame Generator software to decode data.
A modular design allows users to adapt the system to their specific needs.
> Customization of The DSGA
