o Adjust the Signal Delay and Signal Threshold to set the conditions of a No Signal alarm. A signal absence is
declared when the level is lower than the threshold during the selected period.
o Adjust the correction applied to the input signal:
AUTO A START will initiate an automatic sequence, indicated by PROCESS. When the input status
becomes correct it will stop and SUCCESS will be displayed. FAIL will be displayed to indicate that
no correction has been found that will yield to a correct input status.
LENGTH This command allows a manual adjustment of the correction applied to the input signal. The input
status is displayed at the same time to ease the setting.
o Set the input termination to 75 Ohm or to high impedance.
o Adjust the Signal threshold, to set the level below which a low signal alarm will be flagged
o Adjust the Overload threshold, to set the level above which an overload alarm will be flagged
o Configure the different alarms, setting the alarm level (color displayed on the front panel status LED, and
severity reported to the frame controller) and selecting whether the alarm is to be reported on the frame’s GPI
interface.
o Access the firmware version of the card programmable devices.
