Quick Start
Figure 4. Note: The status of LED’s are valid, only if the FPGA_OPERATIONAL LED is lit
Meaning of the status LED’s:
•
DCLK_LOCKED:
If FPGA detects DCLKI and DCLKQ toggling, this LED lights. NOTE: If the board
has been modified for AutoSync to route DCLKQ to the SMA’s, this LED will not be lit.
•
OVER-RANGE_Q-CH:
ADC’s overrange Q-ch pin pulse stretched to around a half second when
overranged.
•
TRIGGER_ARMED:
Lights when “H/W Trigger” is checked inside the Wavevision 5 GUI. Does not
clear upon data capture.
•
ADC_POWER:
Lights when ADC supply voltage of 1.9V is detected.
•
ADC_CALIBRATION:
Will light temporarily when calibration is run. ADC’s CalRun pin is pulse
stretched to about a half second.
•
OVER-RANGE_I-CH:
ADC’s overrange I-ch pin pulse stretched to around a half second when
overranged.
•
FPGA_OPERATIONAL:
Lights when FPGA’s 100MHz reference is locked and FPGA is out of reset.
•
ECM_ENABLED:
Lights when ADC is in Extended Control Mode.
•
RCOUT1/2_ENABLED:
Lights when AutoSync RCOUT1/2 clocks are detected. Enabled when
AutoSync-> DOC (disable output clocks) bit is unchecked in Wavevision 5 GUI.
