7.
Initialize the IF Response calibration step using the niRFSA Initialize Calibration Step VI
or the
niRFSA_InitializeCalibrationStep
function. Set the
calibration step
parameter in the VI to
IF Response Calibration
, or set the
calibrationStep
parameter in
the function to
NIRFSA_VAL_EXT_CAL_IF_RESPONSE_CALIBRATION
.
8.
Initialize the NI PXI/PXIe-5652 using the niRFSG Initialize VI or the
niRFSG_init
function.
9.
Lock the NI PXI/PXIe-5652 to the Reference Clock used by the external test equipment.
Use the niRFSG Configure Ref Clock VI or the
niRFSG_ConfigureRefClock
function.
10. Set the NI PXI/PXIe-5652 power level to 0 dBm using the niRFSG Power Level property
or the
NIRFSG_ATTR_POWER_LEVEL
attribute.
11. Set the NI PXI/PXIe-5652 frequency to 187.5 MHz using the niRFSG Frequency property
or the
NIRFSG_ATTR_FREQUENCY
attribute.
12. Commit the settings to hardware using the niRFSG Initiate VI or the
niRFSG_Initiate
function.
13. Call the niRFSA Initiate VI or the
niRFSA_Initiate
function.
14. Configure the NI 5601 RF signal path to the following corresponding values by setting the
niRFSA RF Path Selection property or the
NIRFSA_ATTR_CAL_RF_PATH_SELECTION
attribute
according to the value referenced in Table 23 or 24 that corresponds to the module
revision of your NI 5601.
