Avtech AVB1-3, Instructions For Use Manual

Page: 6 / 9

GENERAL INFORMATION
BASIC TEST ARRANGEMENT
The AVB1-3 should be tested with a sampling oscilloscope with a bandwidth of at least
2 GHz to properly observe the high-speed waveform. A typical test arrangement is
shown below:
The AVB1-3 generates a positive pulse and a negative pulse internally. These are
added together in the pulse combiner located on the top of the main chassis. The OUT
P to P IN and OUT N to N IN cables shown in the diagram above are preinstalled on the
AVB1-3 (and should never be removed).
The attenuators are required to prevent damage to the sampling oscilloscope. A 40 dB
attenuator with sufficient voltage rating should be used on the main output.
