Some of these things have a grounded sleeve which can be adjusted over the series resistor to add C to ground to balance the across-the-resistor to adjust flatness at the top end.

I use a pair of N-type hard lines with fittings to allow HP vector voltmeter probes to stab the line. Add a precision load and you can calibrate your probe quite well.
