mode of the spectrum analyzer.
When the exponential average mode is selected, after a specified average time is reached, each channel
trace data is weighted exponentially, added to the previous average value and then take the average. In the
exponential average mode, the weight of the new data is larger than that of the old data, which is conducive
to track signals that change slowly. Measured average result will be displayed after the sweeping.
When the repetition average mode is selected, after a specified average time is reached, all the previous
data will be delete and restart the sweeping.
Integ BW: Used to specify the range of integrals to calculating the power in a channel. For example, set the
bandwidth of the main channel. Notice that the integral bandwidth is displayed in a blue box on the screen.
In this case, the sweep span should be set between 1 and 10 times of the integral bandwidth. User can
change the integral bandwidth by using the numeric key, rotary knob, direction key, or touch the panel
menu.
Meas Preset: Reset all parameters of the current measuring mode to factory setting.

: Press average time (on) to specify the average number of sweep to calculating the
measurement results. Sweep time range is from 1 to 999. User can change the average time by using the
numeric key, rotary knob, direction key, or touch the panel menu. Measured average result will be displayed
after the sweeping. Select (off) to turn off this measuring average function.

: Switch between exponential and repetition average mode. When the
specified average time of sweep is reached, this average mode is used to determine the average operation
mode of the spectrum analyzer.
