why not use the Keysight cal service ?

To be honest, I do not like working with them, nor trusting them anymore, since we had few bad experience with their customer support team. (one of the VNA we ordered they promised to have the Impedance measurement software package as default but it wasn't and they just went radio silence)
Also, their build quality has shifted a lot from Agilent era, we had 30 unopend 34470A that was purchased back in 2019 and we opened them up this year then sent to transcat to cal, 1 have a broken front panel USB, 1 have a very noisy reading in the last 2 digits when calibration short was installed. (during incoming IQC, transcat passed them all) and we haven't gone through them all yet.
Their customer service is slow and not really helpful ( we are not a small company, part of FAANG)
Lastly, their animosity towards the home lab community made me decide to move away from them as much as possible.
