2.

Check the LED status to ensure the device is powered correctly. If the LED is blue, the
device is powered correctly using USB. If the LED is orange, the device is powered
correctly using external power.

3.

Connect the device to a different USB port of the host computer, if one is available.

4.

Ensure that the latest drivers are installed for your USB controller.

Direct Connections to the NI 290x

The NI 290x is a precision RF instrument that is sensitive to ESD and transients. Ensure you
take the following precautions when making direct connections to the NI 290x to avoid
damaging the device.

Caution

 

Apply external signals only while the NI 290x is powered on. Applying

external signals while the device is powered off may cause damage.

Ensure you are properly grounded when manipulating cables or antennas connected to the
NI 290x TX1 RX 1 or RX2 connector.

If you are using noninsulated devices, such as a noninsulated RF antenna, ensure the
devices are maintained in a static-free environment.

If you are using an active device, such as a preamplifier or switch routed to the NI 290x
TX1 RX 1 or RX2 connector, ensure that there are no signal transients greater than the
RF and DC specifications for the device that are being generated and sourced to the
NI 290x TX1 RX 1 or RX2 connector.
