3.3.1.3 Voltage, Current and Temperature Display

On the right side of the Status window there is a thermometer display that reports the present temperature of the amplifier. See Figure 3-9, Item [3]. A 20-30°C rise above ambient temperature is typical.

To the left of the thermometer display are several indicators that show various operating conditions of the Compact Outdoor Amplifier in real time. These indicators are helpful for any diagnostic procedures and consist of:

•Power Supply Voltage monitor

•SSPA DC Current monitor

•Regulator Voltage monitor

•Gate Voltage monitor

The Power Supply voltage indicator displays the primary 12 volt power supply output. SSPA DC Current is the total current drawn by the microwave transistors. Regulator Voltage is the DC voltage of the drain circuitry that feeds the GaAs transistors. The Gate Voltage indicator monitors the DC voltage of the gate circuitry of the microwave GaAs transistors. These indicators provide direct access to the active device operating characteristics.

3.3.1.4 Gain Adjustment

The Gain Attenuation Control is located above the Fault Condition Indicators and to the right of the Carrier Enable status. See Figure 3-9, Item [4]. The gain can be adjusted by setting the Attenuation Control. An Attenuation Control of 0 dB is the maximum gain (75 dB) setting on the amplifier. By setting the Attenuation Control to 20 dB; the gain is set to (55 dB). The Attenuation Control can be varied by entering the value into the text box, or by clicking on the up/down buttons.

3.3.1.5 RF Power Indicator

The RF Power indicator is the vertical meter in the central part of the Operation window. See Figure 3-9, Item [5]. This indicator reports the approximate output power of the amplifier. It uses the voltage from the RF Power Detector to determine a corresponding power level in dBm. The accuracy of the power indicator is ±1 dB at the mid-point of the specified band, with a single CW or QPSK carrier.

3.3.1.6 Reference Source

If the amplifier is equipped with a block up converter, the reference source will be indicated above the fault status window. See Figure 3-9, Item [6].
