Nanoscale nuclear magnetic resonance (NMR) signals can be measured throughhyperfine interaction to paramagnetic electron sensor spins. A heterodyneapproach is widely used to overcome the electron spin lifetime limit inspectral resolution. It uses a series of modified Hahn echo pulse sequencesapplied coherently with precession signal resulting in a subsampled NMR signal.Due to challenges with applying high electron Rabi frequencies its applicationis limited to low fields, thus the full potential of the method is not yetexploited at high magnetic fields, beneficial for NMR. Here we presentheterodyne detection utilizing a series of phase coherent electron nucleardouble resonance sensing blocks which extends nanoscale NMR protocols toarbitrary magnetic fields. We demonstrate this principle on a single NV center,both with an intrinsic $^{14}$N and a weekly coupled $^{13}$C nuclear spin inthe bath surrounding single NV centres. We compare our protocol to existingheterodyne protocols and discuss its prospects. This work paves the way towardshigh field nanoscale heterodyne NMR protocols with NV centres which is crucialfor reducing sample volumes and improving chemical resolution.
