The Tektronix Type Z is a comparator plug-in for [[500-series scopes]]. | The Tektronix Type Z is a comparator plug-in for [[500-series scopes]]. | ||
Its maximum sensitivity is 50mV/div, and it achieves 40,000 to 1 common-mode | |||
rejection at DC and low frequencies. Its risetime as a general-purpose | |||
amplifier is 27ns (13MHz bandwidth), but it can track a common-mode risetime of 7ns. | |||
Unlike later comparators, it has a separate step attenuator for each input, | |||
permitting you to view the difference between signals of widely differing amplitudes. | |||
It is also the only comparator that can handle +/- 100V common mode at full sensitivity. | |||
The Type [[P6023]] probe, with R and C compensation, was specifically designed for Type Z. | |||
Type Z was introduced between 1960 and 1962 and uses both tubes and transistors, | |||
capitalizing on each's strengths. | |||
