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.
