The Automotive Test Scope ATS605004D-XMS measures with high resolutions of 14 and 16 bit. A signal measured with the Automotive Test Scope ATS605004D-XMS therefore has 256 times more resolution than most automotive oscilloscopes, which usually have a low resolution of 8 or 9 bit. The high resolution of the Automotive Test Scope ATS605004D-XMS precision automotive oscilloscope allows for measuring signals with more accuracy, because the quantization error is much lower.
The input circuit of the Automotive Test Scope ATS605004D-XMS has a high accuracy of 0.25 % of the full scale input range, where most automotive oscilloscopes have an accuracy of 2 - 3 % of the full scale range.
To display a signal measured with the Automotive Test Scope ATS605004D-XMS High Resolution automotive oscilloscope at the same level of detail as the standard automotive oscilloscope, the display can be 256 times larger. Viewing the signals on a 24" monitor immediately gives a very detailed impression of the signal. The smallest deviations are very well visible and because of the high resolution, it is still possible to zoom in and reveal additional details.
Shown in figure 1 are two displays, both showing a measurement of the same signal. The left display size corresponds to a size comparable to a standard automotive oscilloscope; at 8 bit resolution, zooming will not reveal more details. The right display corresponds to a maximized window on a standard PC screen; at 14 bit resolution, zooming will still reveal more details.
The high resolution and high accuracy of the Automotive Test Scope ATS605004D-XMS and the unlimited zoom of the Multi Channel oscilloscope software allow to zoom in to mV levels. Figure 2 shows a measurement of a 2 mV sine wave made in the 200 mV input range, which is then zoomed in to view the signal at an 8 mV scale.
Highly accurate 1 ppm oscilloscope time base
With a time base accuracy of 1 ppm, frequency and timing can be measured very accurately. The time base of the Automotive Test Scope ATS605004D-XMS is 25 to 100 times more accurate than comparable instruments of the competition.
Coupling multiple instruments to a large combined instrument does not affect the time base accuracy. The timing deviation between the coupled instruments is 0 ppm.
