ATT-64E is a 64 channel RF digital step attenuator system suitable for the frequency range 100 kHz … 8500 MHz. The individual attenuator paths can be easily combined with other components in 50 Ohm technology.
ATT-64E is based on eight ATT-8E Slot-in modules combined in a SR6-11C system platform. It can be controlled either via the integrated high-level controller unit SR6-CU.
To meet the requirements of the future, further modules can be integrated in the system to get an 80 channel RF step attenuator system.
The included controller SR6-CU provides the interfaces LAN and USB. These interfaces can be used to control the ATT-64E system by SCPI-oriented ASCII commands.
ALC and AGC
In combination with the RFLD level detection units, automatic level control (ALC) and automatic gain control (AGC) systems can be realized in an easy and flexible way.
In applications, where shortest response times are required, the switch modules can be controlled via the low-level ‘Binary Interface’ of the SR6-11C system platform.
This interface allows direct programming of the binary data registers inside the ATT-64E modules.
The ATT-64E enables the synchronous execution of multiple commands across all attenuation channels. Additionally, ATT-64E provides a ‘Trigger IO’ interface, which allows the synchronous coupling of multiple SR6-11C based systems and other compatible devices.
