performance will be demonstrated during subsystem on-site acceptance tests. Azimuth and elevation cuts existing satellite will be made beyond first side lobes.
8.8.2 Antenna EIRP
Antenna EIRP will be verified using the following tests. An unmodulated uplink signal level will be measured via the transmit coupler for both the nominal and maximum settings of the FM Modulator output level. The 70-MHz signal will be upconverted without the "sweep" to produce a CW signal for these tests.
At the conclusion of these tests, the 70-MHz signal will then be upconverted with the sweep to show that the gain flatness and the sweep range as measured at the transmit
meet coupler
the specification. This test will be performed at a given upconverter output level setting and output frequency.
i)
HPA 1 will be driven from Command Upconverter 1 at the DISH antenna command frequency. The saturated output power of IPA 1 will be measured. The test will be repeated using IPA 1 and Command Upconverter 2 at the OMNI frequency. The maximum power will also
