contains two waveform points
(2) Time(ind) = TimeSpan + TimeOffset
Example: When sample rate is 250k Sa/s and trigger offset is 500 us.
To calculate time of index point 2:
TimeSpan = (2 – 4096)/(250*2) = -8.188ms
Time(2) = (-8.188+0.5) = -7.688ms
To calculate time of index point 3:
TimeSpan =((3 – 4096)/2)/(250) = (-2047)/250 = -7.686ms
Time(3)=(-8.186+0.5) = -7.686ms
Time(3) ＝ Time(2).
5. Data displays on the screen:
6. Data format of returned screen data:
The screen data obtained by command :WAV:DATA? in Peak Detect mode are stored in
the form of T1max – T1min,T2max-T2min, the format of which is the same as memory
data storage. Because one time contains two points, the waveform data extends to 1200
＝ 600*2.
