will switch to Adjusting Mode, the red box of the selected parameter
(Scan Parameters Types or Scaling) will turn to yellow; one of the digit of
parameter (Start Frequency, Ending Frequency and Mark Points
Frequency) will turn red. The method of adjusting parameter here is as
same as that in Single Point Measurement: Select digit by pressing
Right/Left key, modify the value by turning the knob(Knob button can be
pressed as well, and the function of which is the same as OK key, when
selecting parameter, you can press knob button directly)
When using, please pay attention to adjusting the scaling in terms of
different measuring values, it won’t show the accurate result if the
scaling is inappropriate.
The measured value of the Mark Point in the Scan Function is different
from the value in the Single Point Measurement. In fact, the measured
frequency of the Mark Point is not exactly the accurate frequency at this
point, but the closest value of the scanning frequency. For example, scan
the frequency from 1000MHz to 1280MHz, Mark Point Frequency is set
to 1200.45MHz, the actual measuring value is 1200MHz which is the
closest to 1200.45MHz. If this frequency is just a sensitive point, there
will be a big difference. However, there are two ways to find out the
accurate value: One is subject to Single Point Measurement, the other is
to minimize the scan bandwidth.
