Remember, the output resistor network is only present to protect the measuring instrument from being
over-driven by the device output for high-output signal swings. Desoldering the output matching resistor
and replacing it with a single 50-
Ω
series output resistor that gives only 6-dB output voltage loss at the
measuring instrument is easily done.
