Connecting Signals

Direct Connections to the NI 5690

The NI 5690 is a precision RF instrument that is sensitive to ESD and transients. Ensure you
are making proper direct connections to the NI 5690 to avoid damaging the device.

Caution

 

Apply external signals only while the NI 5690 is powered on. Applying

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

To prevent possible damage to the device, use caution when connecting signal sources and RF
antennas directly to the IN connectors of the NI 5690. Operators, technicians, and all other
users should ensure they are properly grounded when manipulating cables or antennas
connected to the NI 5690 IN connectors.

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 5690 IN connectors, 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 5690 IN connectors.

Torquing SMA Connections

Note

 

A coaxial cable with open ends can function as a capacitor. Before

connecting any open-ended cable to the NI 5690, momentarily short the center and
outer connectors of the cable together.

Note

 

For best results when connecting signals to the NI 5690 front panel SMA

connectors, use shielded low-loss coaxial cables.

Torque all connections to 100 N 

 cm using a standard SMA torque wrench. Apply force

until the wrench clicks.
