Hardware Overview
Note – it is recommended to make all signal connections before applying power to either the VNA
Network Adapter, or associated VETA product.
Note - care should be taken when making connections to the card not to damage the headers or
connectors. Repeated connection and disconnection is not recommended.
Note - that care should be taken to ensure the correct polarity and voltage of the DC supply to
avoid damage to the VNA. There is neither reverse polarity nor over voltage protection on the VNA.

VNA Interfaces
The VNA has connector layout shown in
Figure 2
.
Figure 2 VNA Connectors Layout
The VNA is powered from a 12V DC supply. The power supply employed should be capable of
supplying 12V at up to 500mA, with a voltage tol/-0.5V.
The connectors are described in Table 1
and
Table 2.
