Note This Powerwave product is designed to operate within the normal operating (typical operating) ranges or conditions specified in this document. Operation of this equipment beyond the specified ranges may cause (1) spurious emissions that violate regulatory requirements; (2) the equipment to be automatically removed from service when maximum thresholds are exceeded; or (3) the equipment to not perform in accordance with its specifications. It is the operator's responsibility to ensure this equipment is properly installed and operated within Powerwave operating specifications to obtain proper performance from the equipment and to comply with regulatory requirements. Industry Canada: The Manufacturer's rated output power of this equipment is for single carrier operation. For situations when multiple carrier signals are present, the rating would have to be reduced by 3.5 dB, especially where the output signal is re-radiated and can cause interference to adjacent band users. This power reduction is to be by means of input power or gain reduction and not by an attenuator at the output of the device. 1-4 Ordering Information Table 1-2 lists major system component numbers and descriptions for use in ordering.

Equivalent test equipment may be substituted for any item, keeping in mind that a thermistor type power meter is required. Note All RF test equipment required must be calibrated to 0.05 dB resolutions. Any deviation from the nominal attenuation must be accounted for and factored into all output readings. Table 1-2.

Also verify system performance after any amplifier module is replaced in the field. The test equipment required to perform the testing is listed in Table 1-2, and the test setup is shown in Figure 1-1 and Figure 1-2. Note The frequencies used in this test are typical for an amplifier with a 18 MHz band from 851 MHz to 869 MHz. Select evenly spaced F1, F2, F3, and F4 frequencies that cover the instantaneous bandwidth of your system. To check amplifier performance, proceed as follows: WARNING Do not apply any RF signals to the amplifier input until instructed to do so. CAUTION Ensure that the correct amount of attenuation is used between the amplifier RF connections and the test equipment to prevent overdrive of the amplifier or the test equipment. 1-4.1 Amplifier Spurious Emissions Test: 1. Connect the test equipment as shown in Figure 1-1. 2. Configure the signal source to produce four frequencies evenly spaced across the instantaneous bandwidth to be used for the amplifier under test. 3. Adjust the output of the signal source to excite the amplifier to its rated output. 4. Use the spectrum analyzer to measure the spurious emissions performance. 5. Record test data in Table 5-3. Verify that the data are within the specifications shown in Error! Reference source not found.. 6. Reduce the output of the signal source to minimum. 7. Switch off the Main Power Switch on the amplifier under test.
