The radiation we see today as the CMBR - was this originally released as a pulse or was it continuous for some length of time ?

The original CMB radiation, also known as the cosmic microwave background radiation, has been present in the universe since the Big Bang. It is estimated to have been released about 380,000 years after the Big Bang and has been traveling through space for about 13.8 billion years.
The CMB radiation formed about 380,000 years after the Big Bang. This marks the point when the universe had cooled enough for protons and electrons to combine and form neutral atoms. This allowed the radiation to travel freely through space.
The duration of the CMB radiation has remained constant since it was released about 13.8 billion years ago. However, the wavelength of the radiation has stretched over time due to the expansion of the universe, resulting in it being in the microwave range today.
The CMB radiation will continue to exist for as long as the universe continues to expand. It is estimated that the radiation will eventually become so stretched out that it will no longer be detectable.
The duration of the CMB radiation is measured through observations and measurements of the cosmic microwave background. Scientists use telescopes and satellites to collect data on the radiation's temperature and wavelength, which can then be used to calculate its duration and other properties.
