If you are referring to Bandwidth Analyzer pack (Network Bandwidth Analyzer – Bandwidth Monitor | SolarWinds), its a single pack that includes both the products. So NPM and NTA or Network Bandwidth Analyzer bundle will both work for your requirement.
When it comes to monitoring bandwidth per User and Application there is another option which involves a third party application called LANGuardian. It uses a deep packet inspection engine to capture user and application information from wire data. LANGuardian can integrate with Orion so you retain a single point of reference for all of your network activity. You can access an interactive demo at this link to try it out.
The video below also shows how you can use a combination of SolarWinds UDT and LANGuardian to focus in on top applications and then drill down to locate where problematic devices are plugged into the network.
Hope this helps
