6.1.7 Earth Ground
This test measures the leakage current and verifies that each pin on J8 is connected
correctly. If the ISO/GND compatibility jumper is equipped, it verifies the jumper position. See
Figure 6-3, item
[ 1 ] .
6.1.8 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 6-3, item
[ 2 ] .
6.1.9 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
6-3, item [ 3 ] .
6.1.10 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 6-3, item
[ 4 ] .
6.1.11 Ethernet (if equipped)
Tests Ethernet communication, web monitor and control, and assigns a MAC address to the
unit.
