Product Overview

Mini-Circuits’ ZTDAT series multi-channel programmable attenuator systems are ideal for a wide range
of signal level control applications including transmission loss simulation, signal fading and MIMO
measurements. The 1-6000 MHz operating bandwidth incorporates most of the common

communications bands, supporting applications in LTE, 4G / 5G, IoT, Bluetooth, Zigbee, WiFi and many

more.
Each of the 16 independently controlled attenuator channels within ZTDAT-16-6G95S provides 0 to 95

dB attenuation with more than 100 dB isolation between channels. The system is housed in a compact,
1U height, 19-inch rack chassis, with SMA connectors on the front and rear panels.

The system can be controlled via USB or Ethernet (supporting SSH, HTTP & Telnet protocols). Full
software support is provided, including our user-friendly GUI application for Windows and a full API with
programming instructions for Windows and Linux environments (both 32-bit and 64-bit systems). The full
software and documentation package can be downloaded from our website at:

https://www.minicircuits.com/softwaredownload/multiatt.html.

Mini-Circuits’ novel daisy-chaining interface allows multiple ZTDAT attenuator systems to be cascaded
together into a Master / Slave chain. The full chain effectively becomes one system with every

attenuator channel (from 8 to several hundred) controlled through a single USB or Ethernet connection

and software interface.

Daisy-Chain Control of ZTDAT Systems

Multiple ZTDAT attenuator racks can be combined to form much larger programmable attenuator
systems by daisy-chaining the serial control interfaces. This allows large numbers of attenuator
channels to be controlled through a single USB or Ethernet connection and software interface. All
software commands are issued to the Master unit (the first unit in the chain) which will in turn control all
Slave units as required. The process is:

1. Connect the Serial Out port of the first ZTDAT unit to the Serial In port of the next ZTDAT unit

2. Continue connecting additional ZTDAT units in the same manner, as required

3. Connect the AC power inputs for all ZTDAT units in the chain

4. Connect the control connection (USB or Ethernet) to the first ZTDAT in the chain; this becomes the
Master unit

5. Each individual attenuator channel within the cascaded chain can now be addressed as if they are
part of the Master
