I have a VNA SAA-2N. It will not calibrate (it says it does) but with a 50 ohm load the swr is significantly high. (i have tried another set of standards)

The first thing to check is if something is amiss in the calibration
process you are using. One common mistake is that you need to reset the
cal before doing a new one. You can also verify the cal before you look at
SWR or other measurements. See the detailed description of calibration and
verification in "The Absolute Beginners Guide" in the files section of this
group, at the following link:
