• If the Attenuator module and the reference powermeter are not
hosted by the same mainframe, but the mainframes are connected
via a GP-IB bus to a PC or host computer, GP-IB commands can be
used to perform the calibration steps. The procedures used are
outlined in our Application Note 5988-3159EN : "Variable Optical
Attenuator in BER Test Applications".
