Configuration Settings
Clicking on ‘configuration Settings’ opens a popup window which allows the user to set the
following parameters:
•
Device Address -
o
Set the device's USB address in the 1 – 255 range (factory default 255)
•
Power Up State -
o
For 30, 60 or 90 dB models, Firmware A4 or newer required
o
The attenuator can be configured to power up with isolation setting(factory
default), a user defined attenuation value, or the last attenuation value set
o
In Multi-channel models – the attenuation state each channel will assume on
power up can be set individually.
Notes:
1. If the GUI is not shut down before the attenuator is disconnected the last attenuation
state will not be saved and if “set last defined attenuation” was selected the attenuator
will start up in high isolation state
2. Shutting down and then starting up the GUI repeatedly in less than 3 minutes while “set
last attenuation” is enabled may result in attenuator resetting to isolation state at power
up due to last attenuation state not being recorded correctly.
.

Manual attenuation Step size -
o
Gross tune is the step size for each click on scroll bar.
o
Fine Tune is the step size for the arrows
