The following figures show the front panels of the NI 5185/5186. Descriptions of the LEDs and connectors are shown below.
Early versions of the NI 5185/5186 only support 50Ω input signals. If the front panel of your NI 5185/5186 looks different from the front panels shown above, you may have an earlier version of the device. Check the part number of your device to be sure:
The NI 5185/5186 has two LEDs to indicate status: Access and Active.
The Access LED indicates basic hardware status, as listed in the following table.
|Off||Module is not yet functional, or the module has detected a problem with a power rail.|
|Amber||The device is being accessed or initialized. The Access LED is solid amber during initialization (for approximately 5–10 minutes after startup) and becomes green when this initialization period is complete. While the LED is solid amber, any host-initiated access to daughtercard registers will cause the LED to turn off for about 50 ms. If the steady state was green (that is, initialization was complete), then the LED flashes amber for 50 ms.|
|Green||The module is ready to be programmed by NI-SCOPE.|
The Active LED indicates the module state, as listed in the following table.
|Off||Module is not armed, triggered, or acquiring a waveform.|
|Amber||The module is armed and waiting for a Reference (Stop) trigger.|
|Green||The module has received a Reference (Stop) Trigger, so it is acquiring a waveform.|
The module has detected an error. NI-SCOPE must access the module to determine the cause of the error. The LED remains red until the error condition is removed. Example errors include the following:
The NI 5185/5186 has the following connectors on the front panel.
|REF CLK||SMB jack||Imports an external reference clock to the digitizer.|
|CLK IN||SMA female||Imports an external sample clock to the digitizer.|
|CH 0||SMA female (50Ω)||Analog input connection; digitizes data and triggers acquisitions.|
|CH 0||BNC (1 MΩ)||Analog input connection; digitizes data and triggers acquisitions.|
|CH 1||SMA female (50Ω)||Analog input connection; digitizes data and triggers acquisitions.|
|CH 1||BNC (1 MΩ)||Analog input connection; digitizes data and triggers acquisitions.|
|TRIG||SMA female||External analog trigger connection.|
