Ideally the signal would cross over with zero width at that point, since that is supposed to be the zero-time reference for the time base. If the scope has a histogram function, use it to measure the trigger jitter.
What matters is the time base jitter and wander in the scope.
The UVW-1400 is a recorder/ player with an RS-232 connector for control via an external computer as well as a Time Base Stabilizer, TC generator/reader and a character generator.
It offers external control by a computer, plus a built-in Time Base Stabilizer, TC reader and character generator.
MSOs simultaneously sample analog and digital channels on edges of an internal, asynchronous time base
. This means that on slow time-base settings it always is possible that skew can make one digital signal appear to occur one complete time-base clock ahead of or after another.
The important point is a data sheet comment about the action of the CIS PLL when used with this module: "The recovered clock is used by the [WaveExpert] time base as a reference, and the action of the PLL in the CIS time base removes any residual jitter in the recovered clock, allowing the time-base jitter to be as low as 250 fs rms when the high-stability CIS time-base option is present in the oscilloscope (HCIS)."
The difference is that the reference clock sampler is providing a separate, very accurate timing of the scope time base.
The front-panel design has dedicated knobs for each channel, control of the main and delayed time bases
, and menu keys grouped by function.
In the Agilent Help section, the bandwidths are listed that correspond to each combination of memory length and time base
The records of 24-hour rainfall were entered into written programs with [c.sup.++] and visual basic language for obtaining of maximum rainfall amount in other time bases
from 24 hour to 8784 hour (one year), next output of these program that was 8 records for maximum rainfall in any time bases
entered to excel software, then graph of these records drawn, as on this log-log graph X axis was time (hour) and Y axis was precipitation (mm), after that, a line that covered all of maximum precipitation drawn.
to 24 hours time bases
Konrad (1995) obtained the relation between precipitation, topography and local characteristics for a mountain in south of U.S.
Researchers at NIST have developed a new technique for modeling and implementing a method for minimizing the quantization errors that often accumulate in electronically generated time bases
. A NIST scientist working with staff from Ohio University, examined how time-base distortion causes nonlinear distortion of the electrical waveforms measured by digital sampling instruments, such as digital voltmeters and multimeters, sampling waveform recorders and oscilloscopes.
