Specifications apply to all CSO products. This specification listing below clarifies the CSO operation when used with a probe setting that is either a 10X1 attenuation or a 1X1 setting.
In oscilloscope operation the application of a 10X1 probe enables testing high frequency signals in spite of the effects of the relatively large coaxial cable capacitance that loads the high frequency input signal. It allows the full high frequency scope capability to be realized but it attenuates the signal and the resolution of near ground level signals can be impaired. Using a 12 bit CSO enables viewing low signal levels better than 8 bit CSO
When using the 1X1 probe there is no input signal attenuation which provides better signal resolution at small signals of lower frequencies. The input capacitance of the probe cable will attenuate the higher frequency signals.
As the CSO pod can be situated near the test point – a short test wire (normally low capacitance) can be used to test signals at high frequencies.
Calibration is designed to bring the zero or shorted input t level signal to the zero voltage screen level.
