As a lab exercise, one instructor had the class measure and plot the
frequency response of an 260 and a digital meter (fluke, but I don't
remember the model). The 260 was flat out past 20kHz, the digital meter
response didn't go past 1 kHz. I would never use a digital meter on
anything but 60 Hz circuits unless I had measured the frequency response.
