4.4.3.2.3 Range Switching
Two kinds of range switching are supported. One is Manual ranging which is similar to what 8902A does. For
example, when you use 0dBm and –60 dBm signal to calibrate measuring receiver, while the signal is near 0
dBm and –60 dBm, recal status is displayed, then TRFL Calibrate key should be pressed. In Auto mode, the
TRFL Calibrate key is grayed out, and the range switching can be made automatically depending on SNR.

Example:
4.4.3.2.4 Range Hold
In TRFL measurement, there are 3 ranges which may be used to measure over a range of
>100 dB. This parameter forces the measurement to remain in the current range. One use for this parameter is
when you are measuring unstable signals, which can cause the analyzer to switch between 2 different ranges.
Selecting holds the analyzer in the current range.
