Figure 9 shows the test system used to do dynamic testing
on the HI5714. The clock (CLK) and analog input (AIN)
signal sources are derived from low phase noise HP8662A
generators that are phase locked to each other to ensure
coherence. The output of the generator that drives the
analog input to the evaluation board is first passed through a
bandpass filter to improve the spectral purity of the signal.
The ADC data is captured by a logic analyzer and then
transferred over the GPIB bus to the PC. The PC has all the
software to perform the Fast Fourier (FFT) and do the
required data analysis.

Application Note 9517
A 10-bit accurate DAC is used to do the bandwidth testing.
The input sine wave has a peak-to-peak amplitude equal to
the reference voltage. The CLK and analog input
frequencies are set up so a 1kHz beat frequency is
generated on the output of the DAC. Full power bandwidth is
the frequency at which the amplitude of the digitally
reconstructed output is 3dB down from the low frequency
value.
Refer to the HI5714 datasheet for a complete list of test
definitions and the results that can be expected using the
evaluation board.
