To Verify Bandwidth
The following procedure can be used to test and verify that your probe meets its warranted
bandwidth specification.
Required Test Equipment
Procedure
1
Make connections as described in the following steps.
a
Connect the DP0020A PV fixture to any oscilloscope channel using the SMA
to BNC adapter included in the DP0020A PV kit. The channel to which the
PV fixture is connected is referred to as the PV channel in this procedure.
b
Connect the other end of the DP0020A PV fixture to a SMA cable using the
other SMA to BNC adapter included in the DP0020A PV kit.
c
Connect the other end of the SMA cable to Channel 1 output of the pulse
