Agilent 35670A Specifi cations
Instrument specifications apply after 15 minutes warm-up
and within 2 hours of the last self-calibration. When the
internal cooling fan has been turned OFF, specifications
apply within 5 minutes of the last self-cal i bra tion. All speci-
fications are with 400 line frequency resolution and with
anti-alias filters enabled unless stated otherwise.
