Yes, it is straightforward to build the circuits described in the
standard, but not so trivial for anyone
Brian, et al,
Perhaps you would be willing to share some of your DSoscillograms -
albeit privately, since the IEEE server strips away attachments. (or some
other clever scheme to get them thru).
Regarding the construction of the IEC 60990 TC circuits. Yes, it is

Interesting. During an audit of the facilities of a former employer, the
auditor specifically requested that we didn't use the Simpson 228 for
EN60950 because of the roll-off of the analog movement above 100Hz. The

A meter for IEC 60950 may not be adequate for IEC 61010,
especially if the unit under test has a reasonably high
frequency switch mode power supply.
The high frequencies generated in a switching mode power supply
are negligible in the presence of the mains-frequency leakage
