• Function keys:
• For Power Meter
1st page
[Set Relative] F7: Enables to display the power measurement result using a relative value.
The reference value is the power measurement value immediately before setting the
relative value display.
If the Power Meter screen is switched to another screen or the power is turned off, the
screen enters absolute value display mode and the set reference value is invalid.
[Range Up] F8: Increases the measurement range.
[Adjust Range] F10: Sets the measurement level ranges (RF power meter range and reference level) to the
status appropriate for measurement signal.
(See paragraph 4.3.1, (2))
[Zero Set] F11: Adjusts zero-point of the power meter, as described below.
[Back Screen] F12: Displays the previous screen.
2nd page
[Power Measure Method] F7: Sets the measurement method of Power Measure measurement, selecting Power
Meter or IF Level Meter.
[Power Control Bit Pattern] F8: Sets power control bits. (Initial value: Closed Loop)
Closed Loop: Performs power control of the TX level of the mobile station to
the desired value using the Closed Loop Power Control Bit.
Alternate : Sets power control bits to 0 or 1, alternately.
All 0 : Sets all power control bits to 0.
All 1 : Sets all power control bits to 1.
Auto: Performs the power control in real time operation.
The setting of this parameter is valid on all screens. This parameter can also be
specified in the Power Control Bit Pattern on the Setup TX Measure Parameter
screen. (See paragraph 4.3.6, (1).)
[Closed Loop Power Control] F9:
Displays the closed loop power control menu. (Power Control Bit Pattern: Alternate)
[Closed Loop Up] F7: Increases the TX level of the mobile station by 1 dB.
[Closed Loop Down] F8: Decreases the TX level of the mobile station by 1 dB.
[User Define Level] F9: Sets the TX level of the mobile station to the User Define Level value on the
Setup TX Measure Parameter screen. In this time, the TX level is measured
using the IF Level Meter. So, the Reference Level must be set so that the TX
level and User Define Level can be measured.
[return] F12: Returns to the previous menu.
[BS Output Level Cal.] F11: Performs the level calibration of the BS Output Level. During calibration, the output
signal becomes un-modulated.
[Back Screen] F12: Displays the previous screen.
