Normalize
Before enabling the normalize function, connect the tracking generator output
terminal [Gen Output 50Ω] to the RF input terminal [RF Input 50Ω].
Normalization can eliminate the error of tracking generator output amplitude.
Note: Only when Output under the TG menu is "On" and the current Y-axis scale is
log, can the Normalize menu be enabled.
1.
Normalize
Enables or disables the normalize function. If no saving operation is performed
on the reference trace before enabling the normalize function, the next time you
enable the function, the analyzer will save the reference trace automatically
after it completes the current sweep. During saving the reference trace, a
prompt message will be displayed. When the normalize function is enabled, the
corresponding value of the reference trace will be subtracted from the trace data
after every sweep.
2.
Reference Level
After the normalize function is enabled, you can adjust the vertical position of
the trace on the screen by adjusting the reference level.
Different from the Ref Level sub-menu under AMPT, the parameter
"Reference Level" under "Normalize" will not affect the reference level of
the analyzer once it is modified.
You can use the numeric keys, the knob, and the arrow keys on the front
panel to modify this parameter; also you can modify it on the touchscreen.
For details, refer to descriptions in "Parameter Setting".
