VideoAnalyzer VSA S&H
The MCD VSA is used for functional testing and monitoring. The module in Eurocard format has a serial interface and can be cascaded with other MCD modules. The operation of the MCD VSA is done via measurement software TestManager CE or a special user interface.
By the simultaneous generation of two trigger signals within the test line, the following signal differences can be accurately determined:
- Luma-measurement via two S&H‘s and
- Digital measurement of two data latches.
The two trigger points in the video line in the grid can be adjusted from 200 ns. MCD VSA remotely capable scopes can be used as triggers through the trigger outputs.
Chroma measurements are done using the internal HF-Rectifier. The VideoAnalyzer has the following options for line triggering:
- Triggered by an analog sync separator to FBAS, RGB, SY, sync on green signal
- External H/V sync signals (polarity adjustable via software)
- External flank switch (polarity adjustable via software)
- FBAS Video generator
- VideoAnalyzer for analog video signals
- Used as a transmitter station for analog video signals
- Screening of videoamplifier
- Fully automatic test lines for infotainment systems
- Display test systems
- etc.
