This is only available for Meter and Chart display mode. For Trace
display, please press Meas > Peak Setup > Trace Setup to set the X
and Y scale.

Setting Power Meter Resolution
There are four levels of power meter resolution. Higher resolutions

options represent different resolution as follow:
• [1] = 1
• [2] = 0.1
• [3] = 0.01
• [4] = 0.001
