Berkeley Varitronics Systems BumbleBee-TABLET Manual page 18

IMPORTANT NOTES:
1. The Trigger is only applied for a maximum Span of 20 MHz. Set the Center Frequency to a
suitable value and then set the Span to 20 MHz.
2. The Trigger Threshold Power must be within 20 dB of the Reference Level. If the Threshold
value is below 20 dB of the Reference Level, the BumbleBee Receiver will not trigger. To adjust
the threshold level greater than 20 dB below the reference level, lower the reference level and then
adjust the trigger threshold.
3. Stop the Trigger by clicking "Stop Trigger" to exit the Trigger Mode and resume the normal
Spectrum Mode.
IMPORTANT TIPS WHILE USING THE TRIGGER MODE:
The trigger mode will trigger when the power in a 20 MHz channel exceeds the set power threshold.
The presets can be very helpful in conjunction with the trigger mode.
• Select a channel using the Preset tabs.
• Set the Reference Level and the Resolution Bandwidth.
• Set a threshold value to be within AT MOST 20 dB below the reference level.
• Start the trigger. The receiver will now trigger on the preset channel.
• Click "Stop Trigger" to stop the trigger.
