I misunderstood the manual regarding slew rate.
(Attenuators have no DC trim, so their CMRR is poor)

Unfortunately the divider resistors are fixed, so CMRR is poor except at 50mV/div.

It is also the only comparator that can handle ±100 V common mode at full sensitivity.

Maximum sensitivity is 50 mV/div, and common-mode rejection at DC and low frequencies is 40,000 to 1.
Maximum sensitivity is 50 mV/div, and common-mode rejection is 40,000 to 1 "from DC through audio frequencies".


Risetime as a general-purpose amplifier is 27 ns (13 MHz bandwidth), but it can track a common-mode risetime of 7 ns.
Risetime as a general-purpose amplifier is 27 ns (13 MHz bandwidth).  A side effect of Type Z's unprecedented dynamic range is that transient response is a function of signal amplitude: slew rates faster than 1V in 6ns will cause distortion due to grid current.
