Use USB/GPIB interface such as 82357A/B to connect ENA/ENA-L and external device.
The embedded GPIB card on the ENA / ENA-L can NOT be utilized when ENA/ENA-L is operated as the "System Controller".

[E5070A/71A]
The embedded GPIB card on the ENA / ENA-L can be utilized to control external instruments.
To be the controller, change GPIB Configuration to "System Controller" ([System] > [Misc Setup] > [GPIB Configuration])
