Tektronix specifies the use of "input RC standardizers" in their
calibration procedures for vertical input attenuators. For example,
the procedure for their 1A2 plug-in unit specifies:
Tektronix part no. 011-0073-00, time constant 1 megohm
x 15 pF; attenuation 2X.
What sort of network lives inside the RC standardizer? I'd like to
build one; I imagine a few other folks need one too!
