NI PXI-5404 Calibration Procedure
6.
Repeat the following steps for each frequency in Table 3:
a.
Call
niFgen_ConfigureStandardWaveform()
to configure the sine wave. Set
the following parameters:
•
vi
—The output value
sessionHandle
you obtained from the
niFgen_init
function
•
Channel_Name
—
"0"
•
Amplitude
—
2
•
Start phase
—
0
•
DC offset
—
0
•
Frequency
—The current frequency from Table 3
•
Waveform
—
NIFGEN_VAL_WFM_SINE
b.
Measure the SINE out amplitude using a power meter specified in Table 1. To
determine if the measured amplitude is within the specification of the NI 5404, you
must determine the measurement error of the instrument that you used to measure the
amplitude. You must account for this error when comparing the measured amplitude
to the amplitude passband flatness accuracy listed in the
Specifications for
NI PXI-5404
.
