I hope the cal kit will work for you, but please keep this arrogant individual away from this forum. Otherwise everyone is going to learn that the only correct way of doing things is his way, you will be lectured on required highest industrial standards he expects you to follow, even if all you do is DIY/amateur stuff. Any discussion topic of a device X will receive its "I do not have a device X but ..." comment followed by what he thinks of the device X even if he never owned it. You will be bombarded by liberal use of HP/Agilent equipment and accessories nomenclature that which seems to make him feel important. You will quickly learn his telephone number, address, company name and registration number and when you should and should not call him because his signature will be placed in each and every post because he wants to sell his stuff. Everywhere he showed up on discussion forums he caused heated exchanges because of the way to speak with people.
