Appendix F - TZ50 (Impedance Matching
Output Module)
TZ50 Overview
This module option allows a user to have a 50 Ohm load on the output while
maintaining output amplitude of at least 4 Volts while in the TTL/CMOS mode. All
other functionality of the module is the same as the AT20 modules, including
output while using the Adjustable Mode Function of the channels.
