Attenuator physical setup
The maximum allowed RF input
for programmable attenuators models is reduced
at low frequencies. Check the individual model datasheet and do not exceed the
specified limits.
2.3.1
USB Control (All models)
-Connect USB cable between the attenuator’s USB port and the computer’s USB port.
-Note the attenuator’s USB indicator lights up.
-Connect attenuator input and output SMA ports to your system.
2.3.2
RS232 Control (RUDAT & ZVVA) with power via USB
-Connect D-Sub9 cable between attenuator unit D-Sub port and computer serial port.
-Connect plug suited for available wall socket to the provided power adaptor and plug in
the power adaptor (if a USB bus is available it can be used instead of the power
supply).
-Connect USB cable between supplied power adaptor and attenuator USB port.
-Note the Indicator lights up.
-Connect attenuator input and output SMA ports to your system.
Note:
For RUDAT-13G-xxx verify pins 7-9 in the D-Sub connector are not connected to
any active signal as this may disrupt proper operation.
