If there is a DC voltage across the output load, use a
coupling capacitor in series with the load. The time
constant of the coupling capacitor and load must be long
enough to maintain pulse flatness.
Impedance
Matching
If the waveform generator is driving a high impedance,
such as a 1 MΩ input impedance (paralleled by a stated
capacitance) of an oscilloscope vertical input, connect
the transmission line to a 50 Ω attenuator, a 50 Ω
termination and to the oscilloscope input. The attenuator
isolates the input capacitance of the device and
terminates the waveform generator properly.
