The HP 54600 Series scopes use a complete range of optional interface modules for hard-copy output, remote programmability, and, perhaps most importantly, custom test functionality. These modules plug onto the back of any HP 54600 Series scope and turn a great manual scope into a benchtop automation tool. You can create a true measurement solution for your specific test and measurement needs. No other scope in its class can offer these capabilites and the price is right!
