HPA Enable: When HPA Enable is turned off, the entire amplification chain turned off. In this case the
Shutdown alarm will flash indicating that the system has been shut down by the user.
AGC Enable: When AGC is enabled or ON, the attenuation in the AGC Atten window is determined
automatically by the system. If the AGC is off, the user can decide on the attenuation by changing the value.
OSC Enable: When OSC Enable is ON, the system is checking for oscillation caused by lack of isolation. If
the system detects oscillation The HPA is turned off automatically.
ASD Enable: When ASD is enabled, the system will shut down as soon as the output level reaches the value of
ASD Level.
Over TEMP Enable: When Over TEMP Enable is ON, the system will shut down as soon as the internal
temperature of the system exceeds Over TEMP Level.
VSWR Alarm: When output VSWR is over limit, a VSWR Alarm will occurred.
VSWR: The threshold of VSWR Alarm can be set to 3:1, 6:1 or 9:1.
VSWR Limit(dBm) / Count(Sec): When the output power is low, VSWR measuring is not accurate.
Limit(dBm) sets the output power limitation of VSWR measuring. When you set the limit to 28dBm, VSWR
Alarm will not occur below 28dBm output power even if the output port is opened. Count(Sec) is measuring
the time.
