The issue is with the IDN? command
This returns Hewlett-Packard..... Agilent states that this is intentional for people who previously bought ESA series Analyzers
The NI driver for this instrument (and a series of other Agilent instruments in the same driver) Looks for Agilent|Keysight in the string and so fails the IDN? command.
Not sure how to edit the command as just learning this.
