I've often wondered...
Most people who have an ESD gun have a spectrum analyzer.
Most ESD guns have a multiple discharge setting.
What if you made a coupling strip, such as a 12 inch long x 1 inch
wide piece of copper tape mounted on a board

You are only verifying that the equipment is working so there is no need
to
check absolute levels or waveforms etc

Never done this before, so this is shooting from the hip. If you have a
receiver, as opposed to an analyzer, you could, using sufficient attenuation,
drive the input directly or using some transducer to measure the spectral
signature from dc to daylight right after calibration, and run checks

John,
The IEC TC77b WG-9 made clarification for what was intended to be
understood as verification and what was intended to be a
calibration
that the present standard requires a traceble
calibration as a daily or weekly test, not only a yearly calibration.

I like to repeat: For verification you do not need calibrated
equipment or full bandwidth. The verification is just a method to
increase trust in the calibration. If you use some homemade current
target and a 500 MHz scope, you will get a pretty good picture of the
waveform and detect
