Simplify common power measurement tasks Single-key auto-tuning allows you quickly to home in on the highest- level signal across the bandwidth. Centering this signal on the screen, the analyzer simultaneously reduces the frequency span. Auto-scaling and ranging enhance accurate, speedy measurement. When you find yourself having repeatedly to make the same type of complex measurement or measurement sequence, it is useful to know some shortcuts. That's what we have provided for you in your N9320A spectrum analyzer. You will find that the in-built suite of power measurements shortens routine test set up time by simplifying keypad/menu selection. Selecting these directly from the soft- key menu also helps ensure accuracy of test set up.
