Herein I propose a method to directly measure the space and time dependence of the pair field correlator of a pair density wave. The method is based on two separate ideas. First, I adopt a recently proposed solenoid insertion method to provide the momentum in a tunnel junction. Second, I suggest the use of optimal or overdoped Bi-2201 films as a tunneling electrode with a known charge ordering wave vector which can match the expected pair density wave wave vectors I wish to study. The method is applicable to both fluctuating and ordered states. Potential applications are to the proposed stripe pair density wave order in LBCO and the possible pair density wave fluctuations at finite temperature or in high magnetic field in underdoped YBCO as well as other members of the cuprate family.
