Sine wave performance is measured using the maximum
sample clock rate, at 5 Vp-p, the maximum amplitude
resolution of the DAC (14-bit) and without filters. Spectrum
analyzer settings: Start frequency = 0 MHz; stop frequency =
50 MHz (Nyquist frequency)
0.05% to 100 KHz
< -55dBc for carrier frequencies ≤1MHz
< -40dBc for carrier frequencies ≤5MHz
< -25dBc for carrier frequencies ≤25MHz
Permits division of the memory bank into smaller segments.
Segments may be linked, and repeated in user-selectable
fashion to generate extremely long waveforms.
No triggers required to step from one segment to the next.
Sequence is repeated continuously through a pre-
programmed sequence list (table).
Current segment is sampled continuously, until a trigger
advances the sequence to the next programmed segment.
Current segment is sampled to the end of the segment
including repeats then and idles there. Next trigger
advances to next segment.
