•
Continuous
In continuous mode, the signal continues without interruption.
• Burst Threshold
Sets the burst threshold for the IBUC. This value determines the level at which a
burst is considered valid. The threshold is for the output power level; the threshold
for input power is configured internally.
The value must be between rated power and no less than 2 dB below rated power.
Default values are listed in Table C.2 .
• Burst Timeout
Sets the burst timeout of the IBUC. Burst timeout allows the user to configure a
maximum length between bursts before the IBUC declares an alarm. This
parameter can range from 1 to 300 seconds. A value of 0 disables burst timeout.
• Gain Mode
Options include:
•
Open-Loop ( no feedback in the measuring loop).
Keep in mind the open-loop gain is affected by temperature and frequency;
however, the temperature compensation feature is still active when the unit
operates with open-loop gain. Open is the default setting.
•
Automatic Gain Control (AGC)
•
Automatic Level Control (ALC)
• Attenuation
Type a value within the range of 0.0 dB to 30.0 dB in 0.1 dB steps. After you click
Save Settings , the gain of the unit will be reduced by that value.
•
The default setting is 0.0 dB
