rejection ratio but operating all the way to 20MHz.   
Unlike "comparator" plug-ins such as the [[W|Type W]] and [[Z|Type Z]],
the Type G does not contain an internal precision variable voltage source.  It is for measuring
the difference between two externally applied input signals.
Its maximum sensitivity is 50mV/div.
It has seven tubes.
