Operation Below 45 Hz - Keysight 6811B User Manual

Operation Below 45 Hz

The following operating characteristics apply for output frequencies between 45Hz and 1Hz. Below 1
Hz, instantaneous values meet the dc specifications. The ac source output is set to: sinewave, dc coupled,
real-time regulation, and is connected to a linear load.
