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

This allows DC-coupled measurements of small signals with large DC offsets. 
 
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.

It is also the only comparator that can handle ±100 V common mode at full sensitivity.
 
The Type Z uses two [[turret attenuators]].

The Type Z was [[introduced in 1960]] and uses both tubes and transistors,
capitalizing on the strengths of each.  It was dropped after 1968.
