6.11.1 T/R Port High Power Attenuator
Controls whether additional attenuation is added at the T/R Port. The T/R port has
twoinput paths, one that provides a 16dB attenuator, and the other that bypasses
this attenuator.
–
When ON, the path includes the 16dB attenuator, so the max input level for this
path is +47dBm (50W)
–
When OFF, the 16dB attenuator is bypassed, so the max input level for this path
is +33dBm (2W)
If the attenuator is turned off, the following warning message is displayed and
confirmation that the attenuator is to be turned off is required;
Whenever the attenuator is bypassed (OFF), a warning appears in the status bar:
“Input caution; T/R unprotected"
In the case of an input overload at the T/R input, (>2W with Attenuator off, or >50W
with attenuator on), or an over-temperature at the T/R input, the input is
disconnected, and a dialog is displayed, stating:
“CAUTION! Excessive power has been detected at the T/R Port. The input has been
disconnected. Remove the high signal power and press OK”
