  A time of flight Modulation of IntEnsity by Zero Effort (MIEZE) spectrometer
mode has been developed for the Larmor instrument at the ISIS pulsed neutron
source. The instrument utilizes resonant neutron spin flippers which employ
electromagnets with pole shoes, allowing the flippers to operate at frequencies
of up to 3 MHz. Tests were conducted at modulation frequencies of 103 kHz, 413
kHz, 826 kHz and 1.03 MHz, resulting in a Fourier time range of ~0.1 ns to 30
ns using wavelength band of 4 {\AA}-11 {\AA}.
