19. Measuring Function
When is pushed, the following function menu is displayed.
The measuring function can be selected as follows.
CH POWER ----------- Channel power measurement
ACP ----------------------- Adjacent channel leakage power measurement
OBW ---------------------- Occupied bandwidth measurement
E/F ANT ---------------- Electric field strength measurement
M/F PROBE ----------- Magnetic field strength measurement
FREQ COUNT --------- Frequency counter (factory option)
* Once the measuring function is set, when is pushed, the function menu is directly returned to the last
setting of the measuring function. In order to stop the measuring function or to select the other measuring function,
push [F6] key (MEAS OFF), then the function menu is returned to the main menu of the measuring function.

counter) and the marker function cannot be used at the same time. When is pushed while each of the
four functions is selected, the measuring function will stop.
Similarly, when the measuring function is selected while using the marker function, the marker function will stop.
* Although 501 points can be displayed on the screen, the number of points calculated in the instrument is 1001.
