NI PXIe-5601 Calibration Procedure
Initialize the reference level calibration step using the niRFSA Initialize Calibration Step VI or
the
niRFSA_InitializeCalibrationStep
function. Set the
calibration step
parameter
in the VI to
Ref Level Calibration
, or set the
calibrationStep
parameter in the function to
NIRFSA_VAL_EXT_CAL_REF_LEVEL_CALIBRATION
.
7.
Initialize the NI PXI/PXIe-5652 using the niRFSG Initialize VI or the
niRFSG_init
function.
8.
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.
9.
Set the NI PXI/PXIe-5652 power level to 0 dBm using the niRFSG Power Level property
or the
NIRFSG_ATTR_POWER_LEVEL
attribute.
10. Set the NI PXI/PXIe-5652 frequency to 187.5 MHz using the niRFSG Frequency property
or the
NIRFSG_ATTR_FREQUENCY
attribute.
11. Commit the settings to hardware using the niRFSG Initiate VI or the
niRFSG_Initiate
function.
12. Call the niRFSA Initiate VI or the
niRFSA_Initiate
function.
13. Read the
Initial Device Temperature
using the niRFSA Device Temperature property or the
NIRFSA_ATTR_DEVICE_TEMPERATURE
attribute. You should take the temperature
reading only once, before taking any measurements. Record the
Initial Device Temperature
for use in step 35.
14. Configure the NI 5601 RF signal path by setting the niRFSA RF Path Selection property or
the
NIRFSA_ATTR_CAL_RF_PATH_SELECTION
attribute to the
RF Band
according to
Table 20.
