Please find the sections below to find the general power meter
measurement settings.
Setting the Power Meter Top and Bottom End-Points
Setting the end points (Disk Range) close to expected
measurement value changes the sensitivity of the Power Meter
scale resolution. This is an advantage in viewing small changes in
power. However, this will not affect the overall range of the sensor.

display, please press
Meas > Peak Setup > Trace Setup
to set the X
and Y scale.

Meas > Meas Disp > Dis Range
to access the end-points
menu.

and enter the maximum scale value using the numeric
keypad. Then press

to complete the setup.

and enter the minimum scale value desired using the
numeric keypad. Then press

to complete the setup.
Setting Power Meter Resolution
There are four levels of power meter resolution. Higher resolutions
provide more accuracy but slow the measurement speed. The
resolution is only available for U2000 series power meter and
free-run trigger mode in U2020 series power meter.

Meas > Meas Disp > Resolution
. Select 1,2,3 or 4. The four
options represent different resolution as follow:
• [1] = 1

• [3] = 0.01
• [4] = 0.001
