3 Soft Front Panel
Status Indicator
The Status Indicator window displays the status of the analog outputs of
each channel of the M8121A module.
This include:
•
Data indicates the data source: either “Streaming” data over the ODI
port, or from internal “Waveform” memory.
• Mode reports the selected data format.
• Clock reports status of the sample clock; green means ready and red
means there is no detection of correct clock signal of the selected
sample clock.
• The ODI Sync LED is lit when the ODI port is activated and
synchronized with the data source.
• The ODI FIFO LED is lit when there are brief gaps in the ODI data stream
during otherwise continuous operations. It also indicates when ODI
data starts / flows / stops (for example, when the Rapids play a
recording).
• Gray when inactive (output off, or Data source internal).
• Yellow when ODI is waiting for sync.
• Gray when ODI is synced and there is no ODI data (ODI data rate ==
0 during previous 1s).
• Green when ODI is synced and ODI data is flowing (rate > 0 over 1s
period) without FIFO underflowing.
• Red when ODI is synced and FIFO underflow detected. Remains red
until ODI stops being transmitted (rate == 0 for at least 1 sec).
• Direct Out and Amp Out ports for each channel (indicated by green
LED).
• The Triggered LED is lit when the trigger event is initiated or when the
continuous mode of trigger is selected.
• Continuous mode – Always green when the continuous trigger
mode is selected.
• Triggered mode – Green when trigger action is performed and
grayed out when the trigger is stopped.
• Start button to start the waveform.
• Stop button to stop the waveform.
• Press the ARM button to set to an armed state. Signal generation is
started after a trigger is received. This option is applicable only when
Triggered option is selected under the Trigger Mode drop-down list.
