Generating a Signal Using the NI-RFSG Soft Front
Panel
To verify your device configuration, use the NI-RFSG Soft Front Panel (SFP) in MAX to
generate a simple signal.
1.
Within MAX, select the NI 5650/5651/5652 RF signal generator module in the
configuration tree.
2.
Select
Soft Front Panel
from the MAX toolbar.
The NI-RFSG SFP launches.
3.
Within the NI-RFSG SFP, specify a frequency and a power level for signal generation.
Caution
Clicking
RF On/Off
generates a signal from the RF OUT connector
of the NI 5650/5651/5652 front panel. Disconnect any equipment that can be
damaged by the test signal prior to clicking the
RF On/Off
button on the
NI-RFSG SFP.
4.
Click
RF On/Off
to begin signal generation.
Note
Refer to the
Troubleshooting
section of this document if an
ACTIVE LED does not turn on or if the NI-RFSG SFP generates an error.
During signal generation, the ACTIVE LED on the NI 5650/5651/5652 hardware module
illuminates.
5.
Click
RF On/Off
to stop signal generation.
