trace can now be moved to a different position on the
display by changing the normalized reference position.
This may be useful if the device to be tested has positive
gain, such as an amplifier. Now replace the thru line with
the device under test, and an accurate measurement of
the gain or loss can be made.
• Norm Ref Lvl
Sets the level (in dB) of the normalized reference.
• Norm Ref Posn
Offsets the displayed trace without affecting the
instrument gain or attenuation settings. This allows
the displayed trace to be moved without decreasing
measurement accuracy.
• Ref Trace
Allows you to view or blank the reference trace on the
display.
Power Meter
Key access:
[MODE] > {Power Meter}
Use the arrow keys to highlight the mode.
Select this mode, and press

to make a
measurement using the power meter function. When
selected, the Power Meter softkey menu will be
displayed and many of the instrument hardkeys will be
disabled as they are not necessary for this mode.
Zeroing
Key access:
[MODE] > {Power Meter} > {Zeroing}
Access the associated Zeroing submenu.
• Zeroing
Make a Zero operation of the power sensor.
The U2000 Series USB Power Sensors have their
sensor calibration tables stored in non-volatile
memory which means that the reference calibration
factor is automatically loaded upon power-up.
