Unfortunately the divider resistors have no trim, so CMRR is poor except at 50mV/div. | |||

Maximum sensitivity is 50 mV/div, and common-mode rejection | Maximum sensitivity is 50 mV/div, and common-mode rejection is 40,000:1 "from DC through audio frequencies". | ||
Risetime as a general-purpose amplifier is 27 ns (13 MHz bandwidth) | 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. | ||
