5.1.7 Earth Ground

This test measures the leakage current and verifies that each pin on J8 is connected

correctly. See Figure 5-3, Item [1].

5.1.8 Sample Port

The RF Sample Port is measured at discrete frequencies across the band and a calibration

label is placed near the Type N connector on the bottom of the unit. The sample port is

approximately -40 dB from the RF output level. A label with the exact coupling ratio is

attached to the amplifier chassis. See Figure 5-3, Item [2].

5.1.9 P

1dB

and P

sat

The 1dB Gain Compression Point is measured at discrete frequencies across the band to

characterize the output power over the operating frequency range. The P

1dB

measurement is

a guaranteed minimum specification.

As the input power increases, the output power limits to some maximum level. This is defined

as the saturated output power or P

sat

. The P

sat

specification is a typical value and is not

guaranteed. This is due to the variation that exists among microwave power semiconductors.

The saturated output power is typically 0.5 dB to 1.0 dB above the P

1dB

value. See Figure

5-3, Item [3].

5.1.10 I/O Test

This test verifies that the unit has the correct wiring on the MS connectors by testing faults,

communications, and redundancy. See Figure 5-3, Item [4].

5.1.11 Ethernet

Tests Ethernet communication, web monitor and control, and assigns a MAC address to the

unit.
