Information
The Fluke I92B/196B-C7199B-C ScopeMeter test tools have
three input channels that are electrically floating with
respect to each other, and with respect to the power adapter
input.
Channel A and channel B are Oscilloscope channels with a
60/100/200 MHz bandwidth. The Meter/External Trigger channel
is a combined DMM and external trigger channel with a
limited (10 kHz) bandwidth.
The B versions have a black&white LCD, the C versions have a
color display.
