For 12-bit mode, there are 4096 DL's (digitizing levels) in a captured waveform. For 8-bit mode, there are 256 DL's. DL is the abbreviation for digitization level. A DL is the smallest voltage level change that can be resolved by an A-D Converter. This value is also known as an LSB (least significant bit).

In an un-zoomed time-domain waveform plot, the full vertical scale of the plot (in 12-bit mode) is 4000 DLs ±48 DLs "off-screen" but are still available for measurements, analysis, and download.

In 8-bit mode, there are 250 DLs displayed. ±3 digitizing levels are "off-screen" but are still available for measurements, analysis, and download.

Delta-time measurement accuracy, nominal

The formulas to calculate the peak-to-peak or rms nominal delta-time measurement accuracy (DTA) for a given instrument setting and input signal is as follows (assumes insignificant signal content above Nyquist frequency):

Where:

N = RSS of input-referred noise (V_RMS) and dynamic noise estimate (V_RMS)

SR ₁ = Slew Rate (1^st Edge) around 1^st point in measurement

SR ₂ = Slew Rate (2^nd Edge) around 2^nd point in measurement

Dynamic noise is noise that appears with a signal applied (such as distortion or interleave errors).

Dynamic noise estimate =

Tj = aperture uncertainty (sec rms - 80 fs for short durations)

t _p = delta-time measurement duration (sec)

TBA = timebase accuracy or Reference Frequency Error (which is 20 ppb)

(Assumes insignificant error due to aliasing or over-drive.)

The term under the square root sign is the stability and is due to TIE (Time Interval Error). The errors due to this term occur throughout a single-shot measurement. The second term is due to both the absolute center-frequency accuracy and the center-frequency stability of the timebase and varies between multiple single-shot measurements over the observation interval (the amount of time from the first single-shot measurement to the final single-shot measurement).

Note:The formulas assume negligible errors due to measurement interpolation, and apply only when the interpolated sample rate is 25 GS/s or higher.
