1.0 Purpose This test procedure is for Manufacturing to confirm the proper operation of
an S-band PD2 transmitter combined with a Stealth power amplifier.



2.0 Scope This procedure verifies the output power of an additional Power Amp when
integrated with a S Band PD2 transmitter. The PD2 transmitter is a final tested unit and
the power amp is a purchased part, 8720781.


3.0 Definitions / Acronyms

DUT – device under test
PA – power amplifier



4.0 Notes
Preliminary Setup:


1. Set the main DC supply to 12.0 Vdc, current limit to 7.0 amps, output off. Set the
   control DC supply to 5.0 Vdc, current limit to 50mA, output off.
2. Connect the power supplies to the DUT terminal block as shown in Figure 1 using
   suitable gauge wire. 18 AWG for 12 volt, 24 AWG for the control.
3. Except as noted the spectrum analyzer controls should be set to AUTO.
4. This test procedure assumes a fully tested Palladium II transmitter is installed in the
   DUT.
5. Although this is a 5 Watt TX, care is taken to not exceed 4.8 watts when operating at
   12.0 volts so as not to exceed 5 watts if operated at 13.8 volts. FCC rules do not
   permit greater than 5 watt RF output.

Note: Click the Read button in the Globals section to retrieve current settings.

Setting Channel to program:
                   Enter the channel into the Config field or use the up/down arrows to the right of the
Config field. If Link is checked, the receiver changes channels as the Config field is changed.

Setting Channel Frequency:
                 To set the Channel Frequency, Select the channel to program using the above step then
enter the channel frequency into the Rx Frequency box in the utility. Ensure the Down Converter LO is
correct for the appropriate band (refer to appendix A.) Ensure Unit Name and Encryption settings match
customer specifications. Then click the Commit All button on the utility.

Note: All Bands DVBT Polarity = Normal
