AMPLITUDE DECAY TIME
When reducing the amplitude, it may take several tens of seconds for the amplitude to
fall to the set amplitude as the internal capacitor banks discharge.
THE LOAD AND OUTPUT MODULE
The AVOZ-D2-B has five identical outputs. These outputs can either be combined to
drive a single low-impedance (10 Ohms) load, or can be used separately to drive
multiple 50 Ohm loads simultaneously.
An output module is optionally available to simplify the connection of a single load to
multiple outputs. Up to five identical 50 Ohm coaxial cables (152 cm / 5 feet) are used
to connect the mainframe to the output module. Not all cables are necessarily used at
the same time; see the table below for recommended cabling when using the output
module to drive a single load.

For instance, to drive a single 10 Ohm load, the following configuration should be used:
