Application Note 9725
sample clock input of the HI5746. The ADC data is captured
by a logic analyzer and then transferred over the GPIB bus
to the PC. The PC has the required software to perform the
Fast Fourier Transform (FFT) and do the data analysis.
Coherent testing is recommended in order to avoid the
inaccuracies of windowing. The sampling frequency and
analog input frequency have the following relationship: f I /f S =
M/N, where f I is the frequency of the input analog sinusoid,
f S is the sampling frequency, N is the number of samples,
and M is the number of cycles over which the samples are
taken. By making M an integer and odd number (1, 3, 5, ...)
the samples are assured of being nonrepetitive.
Refer to the HI5746 data sheet for a complete list of test
de?nitions and the results that can be expected using the
evaluation board with the test setup shown. Evaluating the
part with a reconstruction DAC is only suggested when
doing bandwidth or video testing.
Video Testing
Figure 6 shows how a test system can be con?gured to do
video testing of the HI5746 with the DAC reconstruction
board and the HI5746EVAL1 evaluation board. The
appropriate test waveform is generated by a video source
such as the TSG100 or TEK1001 from Tektronix and applied
to the converter. The digitized video is converted back to
analog by the reconstruction DAC for evaluation by a video
analyzer, TEK VM700.
Since the HI5746 is a 10-bit A/D, install jumpers JP1 and
JP2 on the DAC reconstruction board to tie the DAC two
LSB’s high. Install JP3 so that the video out of the
reconstruction board will have negative going sync. JP5-9 on
the DAC reconstruction board are utilized to establish the
correct clock/data timing relationship into the DAC.
Set up the HI5746EVAL1 evaluation board for video testing
by following the procedures outlined previously in the
HI5746EVAL1 evaluation board application note on the
video input con?guration and single-ended DC coupled
analog inputs. Input the video signal to the HI5746EVAL1
evaluation board through the SMA connector marked
VIDEO. Note that all cables carrying video should be 75 ? .
Finally, mate the DAC reconstruction board P1 connector to
the HI5746EVAL1 evaluation board P2 connector. Correct
alignment between the two boards will have P1 pin 34 of the
DAC reconstruction board plugged into P2 pin 25 of the
HI5746EVAL1 evaluation board.
See Application Note AN9419 “Using the DAC Reconstruct
Board” for additional applications information.
