BASIC AMPLITUDE CONTROL
The basic test arrangement for the AVR-EBF6-B is shown in the figure below:
The mainframe connects to the rise time filter using a 60 cm length of SMA-to-SMA
coaxial cable.
The output of the filter connects to the test jig using another 60 cm length of SMA-to-
SMA coaxial cable.
A DB-9 control cable connects the mainframe to the test jig, to control the safety
interlocks.
The test jig main output is fed into the 50 Ohm input of an oscilloscope by a 60 cm
length of BNC-to-SMA coaxial cable, as is the monitor output.
