mAs Measurement Calculates Current Over Time
Using the cursors, you can now measure directly the amount of radiation produced by X-ray systems, or the total amount of charge applied to a system.

Smart Averaging
Smart averaging gives the averaged waveform over successive acquisitions, reducing noise in the displayed waveform. Thanks to smart averaging, you can now also see an incidental curve of a different waveshape with no effect on the averaged curve! This allows you to see the averaged curve of a sequence of video lines, for example, while still seeing the incidental flyback line flash by! Thanks to smart averaging, the oscilloscope gives an immediate response when the signal makes large changes, for instance when probing around different test points, while retaining the benefits associated with averaging!

Extended Offset
Vertical offset is now extended to a maximum of 16 divisions, allowing vertical zoom-in for study of small details of the signal.

Selectable Persistence
Persistence mode with selectable decay time helps to find anomalies in the waveshape and optimizes the display for color information when working with composite color video. Can be used together with dots only mode, best for modulated signals, or with dot join mode for more continuous and stable waveshapes.
Extended Video Triggering
Next to its triggering capability for standard, interlaced TV signals, the instrument now triggers on high-resolution, non-interlaced video systems. The ScopeMeter 190 will trigger on all lines (non-selective), or can select an individual video line from systems with up to 2800 lines per frame.
MA190 Accessory Kit
The MA190 accessory set enables interconnection of the Fluke 190 for use in the field of Medical Imaging and Video systems. The kit is included in the Fluke 190M as a standard.
The accessory kit includes:
- 50 ohm BNC feedthrough terminator, in insulated enclosure, to maintain proper termination of test connections during measurement.
- 50 ohm BNC terminator with 10:1 signal attenuation; keeps test terminal properly loaded while getting optimum signal amplitude to benefit from the instrument's extended offset range.
- 1 ohm current shunt for current measurements, in insulated enclosure.
- safety-designed BNC cable, 1.5 m (5 ft), with plastic connectors for safe connection to test terminals even when not at ground potential.
- insulated BNC(f) to 4 mm banana plug adapter.
- dual 4 mm banana receptacles (1 red, 1 black).
