Initiates a digital averaging routine that averages the trace points in a number of
successive sweeps, resulting in trace “smoothing.” You can select the number of sweeps

average number further smooths the trace. To select the type of averaging used, press

• a new average number is entered.
• any measurement related parameter (e.g., center frequency) is changed.
• Restart is pressed.
• Single Sweep is pressed.
In single sweep, the specified number of averages is taken, then the sweep stops. In
continuous sweep, the specified number of averages is taken, then the averaging continues,
with each new sweep averaged in with a weight of and the old average
