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.
