TZ50 Impedance Matching Output Module
This module option allows a user to have a 50
Ω
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.
TTL/ADJUSTABLE OUTPUTS
TTL/CMOS Mode
Output Level
4.0 Volts typical into 50
Ω
Rise Time
3 ns
Slew Rate
>0.5 V/ns
Jitter – Channel to Channel
<50 ps RMS
Adjustable Mode
Output Resolution
10 mV
Current
200 mA typical, 400 mA max (short pulses)
Slew Rate

*Note: The TZ50 module has significant overshoot and ringing through high
impedance (see figure).
