-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]], [[introduced in 1960]] and dropped after 1968.
-Its two main subsystems are a differential amplifier and a precision variable
-DC voltage source, which can be used as one of the amplifier inputs.
-This allows DC-coupled measurements of small signals with large DC offsets.
-Its maximum sensitivity is 50 mV/div, and it achieves 40,000 to 1 common-mode
-rejection at DC and low frequencies.  Its risetime as a general-purpose
-amplifier is 27 ns (13 MHz bandwidth), but it can track a common-mode risetime of 7 ns.
 The Type Z has two inputs, A and B, plus a precision comparison voltage, V<sub>C</sub>, that is

+Unlike later comparators, Type Z has separate step attenuators for each input,
 permitting the user to view the difference between signals of widely differing amplitudes.
