Making a Power Measurement with USB Power Sensor
Power Meter Settings
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. 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.
1 Press Meas > Meas Disp > Dis Range to access the end- points
menu.
2 Press To p and enter the maximum scale value using the
numeric keypad. Then press dBm to complete the setup.
3 Press Bottom and enter the minimum scale value desired
using the numeric keypad. Then press dBm 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..
Press Meas > Meas Disp > Resolution. Select 1,2,3 or 4. The four
options represent different resolution as follow:
• [1] = 1
• [2] = 0.1
• [3] = 0.01
• [4] = 0.001
