National Instruments NI 5670 用户手册

Inadequate air circulation could cause the temperature inside the chassis to rise 

above the optimal operating temperature for the NI RF signal generator, potentially causing 
thermal shutdown, shorter lifespans, or improper performance.

♦ NI 5670/5671/5672

Under conditions of proper air flow and 25 °C (63 °F) ambient 
temperatures, the NI 5610 upconverter module operates at internal 
temperatures of approximately 45 °C (113 °F), the NI 5421 module 
at approximately 51 °C (124 °F), and the NI 5441/5442 module at 
approximately 58 °C (136 °F).

♦ NI 5650/5651/5652

Under conditions of proper air flow and 25 °C (63 °F) ambient 
temperatures, the NI 5650/5651/5652 operates at internal temperatures 
of approximately 38 °C (100 °F).

If the NI RF signal generator has been in use, it may exceed safe handling 

temperatures and cause burns. Allow the NI RF signal generator to cool before removing 
it from the PXI chassis.

NI recommends that you install PXI slot blockers between the NI RF signal generator 

and adjacent hardware modules to maximize cooling air flow.

6. Interconnecting the NI 5670/5671/5672 Modules

The NI 5670/5671/5672 hardware modules interconnect through 
the front panels. Complete the following steps to interconnect the 
NI 5670/5671/5672 hardware module front panel connectors as shown 
in Figure 5.

1.

Connect the INPUT connector on the NI 5610 upconverter module to 
the CH 0 connector on the NI 5421/5441/5442 AWG module.

2.

Connect the TO AWG CLK IN connector on the NI 5610 upconverter 
module to the CLK IN connector on the NI 5421/5441/5442 AWG 
module.

Published NI 5670/5671/5672 RF signal generator specifications assume use of the 

included cables. Substituting different cables may affect performance.
