Thank you for your post.
The cost of calibration depends on the unit, the standard charge for a PS3000 is Â£50 plus tax and delivery.
We have a turnaround time of 5 working days from receipt of the unit and payment. The calibration comes with a certificate which is valid for one year. All scopes are tested before they are sent out, however calibration is extra. We do not offer discounts on calibrations.
Hope this helps
