Electronics engineers will no longer have to ship test equipment to standards
labs to get it calibrated. Last week Britain鈥檚 National Physical Laboratory in
Teddington made its database of radio frequency measurement standards available
online. Users anywhere in the world can log on to NPL鈥檚 server鈥攑erhaps
using a cellphone modem鈥攁nd the software will interrogate their
measurement equipment to see if it has strayed from known frequency standards.
British Aerospace expects the system to cut calibration costs tenfold.
