The Fluke 190 Series Medical ScopeMeters are high-performance oscilloscopes for the most demanding applications when servicing medical imaging equipment and video systems. Based upon the Fluke 190 Series ScopeMeters, the Fluke 190 Series Medical ScopeMeter offers measurement capabilities optimized for servicing medical equipment in the following modalities: X-ray, MRI, Nuclear Medicine and Ultrasound.

Dual input - 100 or 200 MHz bandwidth Up to 2.5 GS/s real-time sampling per input mAs current-over-time measurement Connect-and-View™ automatic triggering, a full range of manual trigger modes plus external triggering Video triggering with line selector for standard and high-resolution video systems Smart averaging Selectable persistence mode 27,500 points per input record length using ScopeRecord™ mode Automatic capture and replay of 100 screens Automatic waveform measurements Four hours rechargeable NiMH battery pack 1,000V CAT II and 600V CAT III safety certified Up to 1,000V independently floating isolated inputs Includes a 5,000 counts true-rms multimeter and a TrendPlot™ paperless recorder FlukeView Software, Carrying Case and accessories included

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).

Oscilloscope Mode
Display and acquisition	Channels displayed:  input A, input B, dual channel Display modes:  smart averaging, normal averaging, selectable persistence, invert, replay  Smart averaging displays averaged curve; incidental waveforms that differ too much from the average curve are displayed but do not contribute to the averaged curve Averaging factor:  selectable: 2x, 4x, 8x, 64x or off Selectable persistance decay time:  short, medium, infinite or off; can be used with dots only display or with dot join mode
Trigger and delay - Video Triggering	Interlaced video:  NTSC, PAL, PALplus, SECAM. Selects field 1, field 2, lines or on user selected line from a frame Non-interlaced video:  for line counts up to 2800 lines per frame and and video scan rates up to 65 kHz; triggers on fields, on lines or on user-selected line
Cursor measurements	Dual vertical lines:  time between cursors, voltage between markers, 1/T (in Hz), mVs, mAs
Zoom	Horizontal zoom:  Up to 8x Vertical zoom:  using position control (offset) and vertical sensitivity
Offset range	Max. offset for viewing positive-going signals:  16 divisions for input sensitivity settings 5…50 mV/div (50…500 mV/div. when using 10:1 probe or TA190-50R); 8 divisions for all other vertical sensitivity settings     Max sensitivity of Fluke 190CM:  2mV/div (20mV/div. using attenuator)     Max. offset for viewing negative-going signals:  8 divisions for all vertical sensitivity settings
