Back in time a FLUKE employ made the thought to hide FLUKE 8845A 8846A AC Filter bandwidth information at the calibration document, instead this information be at User Manual.
Today I was exploring HP/Agilent/Keysight 34401A user manual and this AC Filter bandwidth information was clearly described.
The new information this is that both brands they use at that class of benchtop DMM, three identical AC Filter bandwidth options.
Instead of me reinventing the wheel, I will simply copy/paste the relative text:
AC Voltage Specifications
AC Voltage specifications are for ac sinewave signals >5 % of range.
For inputs from 1 % to 5 % of range and <50 kHz, add an additional error of 0.1 % of range, and for 50 to 100 kHz, add 0.13 % of range.
Maximum Input:
750 V rms or 1000 V peak (8845A)
1000 V rms or 1414 V peak (8846A) or 8 x 10 7 volts-Hertz product (whichever is less) for any range.
Measurement Method AC-coupled true-rms.
Measures the ac component of input with up to 1000 V dc bias on any range.
AC Filter Bandwidth:
Slow 3 Hz -300 kHz
Medium 20 Hz -300 kHz
Fast 200 Hz -300 kHz
