I have a used HP 85990A Multi-carrier signal generator with no documentation or PC software to configure it.
HP only sold in the catalog in 1997 and 1998. It is used to perform analog distortion testing on cable TV distribution
amplifiers. Keysight has no reference to this equipment what so ever.
Thanks,
Jim
