5.3.1
System Calibration and Configuration Menu
The Calibration Menu also allow for various features to be enabled or
disabled on the system. To enter the system configuration mode press and
hold down both the and
buttons while the unit is powered up. When
the display reads “Calibration”, release the two buttons. The unit now
displays the main system configuration menu. Using the
↑
and
↓
buttons,
select the option to configure, and press the ‘MODE’ button to configure
that option. A detailed explanation of all of the options is described below
(and on Table 8, page 34).
5.3.1.1 Forward Power
This option calibrates the dBm scale used by the display. Before
this step can be completed, the VVA levels must be calibrated.
To perform the Forward Power calibration, the amplifier must be
attached to an external RF power meter via a load, with a
continuous wave input source to the amplifier. Also, the
directional coupler must be configured for forward power
calibration.
Example:
Unit:
Top line displays: “Using the 'UP' and 'DOWN' buttons,
adjust the output power to match the level below, and
press the ‘MODE’ button.”
Second line displays: “Fwd Pwr=27.0 dBm”
User:
Use the
↑
and
↓
buttons to adjust the output power so
that the power level read on the RF power meter is 27.0
dBm. Then press the ‘MODE’ button.
Unit:
Top line displays: “Using the 'UP' and 'DOWN' buttons,
adjust the output power to match the level below, and
press the ‘MODE’ button.”
Second line displays: “Fwd Pwr=28.0 dBm”
User:
Use the
↑
and
↓
buttons to adjust the output power so
that the power level read on the RF power meter is 28.0
dBm. Then press the ‘MODE’ button.
The user can back up (e.g., go from 32.0 dBm to 31.0
dBm) by pressing the ALC button.
This process continues until all of the calibration points have
been taken. After all of the forward power levels have been
calibrated, press the GAIN button, then the unit returns to the
main System Configuration menu.
