• 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”.
