The recent upgrade to MWAX necessitates verification that the system is capable of observing high time resolution phenomena, such as pulsars. To this end, we put in a successful proposal for an MWA observing campaign to being in the end of 2021 and into the beginning of 2022. The requested observations fall into two categories:

1. commissioning observations, and
2. the remaining SMART observations.

This page details the progress made in taking the observations and performing the tests to complete the commissioning phase. Progress with the SMART survey is detailed elsewhere.

Commissioning Observations

Goals & Target Pulsars

The stated goals of the commissioning observations are:

1. To develop and test the tied-array beamformer for the new VCS data format
2. Verification of frequency labelling
3. Data recording and timing stability
4. Polarimetric verification and leakage assessment
5. Full coherent beam sensitivity and timing accuracy
6. The voltage dump and trigger mode (in response to external triggers)
7. Correlation and imaging of data recorded in the new VCS format

A partial list of requested observations to satisfy the above goals are:
