Agilent 35670A
Specifications
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-calibration.
All specifications are with 400 line frequency
resolution and with anti-alias filters enabled
unless stated otherwise.
