3.2 Anti-alias filters and alias exposure-free mode

The broadband VSA can be configured to be essentially alias-free by using the full rate sampling mode and installing an external lowpass filter on the digitizer input. Use BNC-f to SMA-m and SMA-f to BNC-m adapters to connect the filter’s SMA connectors to the digitizer in case the digitizer has BNC connectors.

2.For the HF input a 300 MHz lowpass filter will avoid aliasing from signals above 300 MHz, but in-band and out-of-band aliasing is still possible since full rate mode is not supported with the HF input.
