OUTPUT ENABLE/DISABLE
When this mode is selected, the display will read: Output Enabled
or
Output Disabled
Pressing the Up or Down buttons will toggle the display between Enabled and Disabled. When enabled, the RF output from the
MA4061B Upconverter is enabled. When disabled, the RF output from the MA4061B Upconverter is disabled.
( An RF output is only present when there is a valid IF input configured as described in the previous sections.
This means that at the time of shipping, the output is disabled until a valid input is applied.
IF AND RF ALARM THRESHOLD SETTING
The IF and RF alarm threshold can be configured by the user via remote control.
Default settings are as follows: IF +4, -4 dB, alarm function enabled
RF -15, +4 dBm, alarm function enabled
The IF and RF alarms can be independently enabled or disabled via remote control. Refer to Section 6.5, Detailed Command
Descriptions and System Responses for instructions on how to adjust these settings.
DEFAULT SETTINGS
At the time of shipping from factory, the default settings of the MA4061B are:
AUTO IF AGC enabled
IF & RF Thresholds enabled
Output is disabled (until a vaild input is supplied)
The default status code at the time of shipping is s0E. Once a valid input is applied, this status will change.
3.2.2 MA4070C Power Amplifier Modes
FORWARD POWER
When this mode is selected, the display will read: Fwd Pwr XX.X dB
The display indicates the approximate RF power at the output of the MA4070C power amplifier. To adjust the RF level, use the
UP/DOWN buttons. Note that since the MA4070C is a fixed gain device, the MA4367 transmitter actually adjusts the RF output
power of the MA4061B upconverter. Therefore any changes made to the MA4070C output level will also be reflected in the
MA4061B output level. The RF level is measured by the internal RF power detector at the output of the MA4367 power
amplifier. The detector measures from +20 dBm to +40 dBm. It is recommended to use a calibrated external power meter for
accurate setting of the power level.
( If operating by remote control, adjustments of the forward power level cannot be made directly. The power
must be adjusted by altering the MA4061B output level.
REVERSE POWER
When this mode is selected, the display will read: Rev Pwr XX.X dBm
The display indicates the approximate RF power level returned to the card from mismatched connections, etc. The detector measures from
+20dBm to +40dBm
