Switching Solutions
The BitifEye 2100 series is a modular and scalable switching system. Five slots can be equipped with 2:1, 4:1, 6:1 or 8:1 switch modules, with a bandwidth from DC up to 26.5 GHz.
We provide several application specific configurations, which are also connected to our ValiFrame N5991 / N5990A test automation software. Apart from this it is also possible to customize your own switch system and control it either manually or using your own control software.
Advantages
- Quick multi-lane testing for receiver (RX), transmitter (TX), cable and connector DUTs
- Highest level of test automation
- Fastest test execution, shortest test times
- Provides high throughput and higher testinstrument availability
- Ultimate data quality
- Fully integrated software
- Minimum wear for instrument and cable connectors
Application Specific Switch Systems
In order to use them together with Keysight Tx scope applications, it’s already integrated. Just connect and select it.
For Receiver tests in our Test Automation Software ValiFrame N5991 / N5990A , use the add-on option of “Switch System Support”
