ScopeMeter 190B Series: Speed, performance and analysis power
 
For demanding applications, the 190B Series high-performance oscilloscopes offer specifications usually found on top-end bench instruments. With up to 200 MHz bandwidth, 2.5 GS/s real time sampling and a deep memory of 27,500 points per input they’re ideal for engineers who need the full capabilities of a high-performance scope in a handheld, battery powered instrument.
 
• Dual input - 200, 100 or 60 MHz bandwidth
• Up to 2.5 GS/s real time sampling per input
• High Waveform Resolution of  3000 datapoints per channel
• Connect-and-View™ automatic triggering, a full range of manual trigger modes plus external triggering
• Fast display update rate for seeing dynamic behavior instantaneously
• Automatic capture and replay of 100 screens
• 27,500 points and more per input record length using ScopeRecord™ mode
• 1,000 V CAT II and 600 V CAT III safety certified
• Up to 1,000 V independently floating isolated inputs
• Four hours rechargeable NiMH battery pack

Visible screen width: 12 divisions

Waveform mathematics: A + B, A - B, A * B, all with user selectable scaling of resultant; A versus B (X - Y-mode);
Acquisition modes: Normal, auto, single shot, ScopeRecordroll, glitch capture, waveform compare,
 
 
Trigger and Delay
Source: Input A, input B, external trigger input. All input references isolated from each other and from ground
 
Modes: Automatic Connect-and-View,free run, single shot, edge, delay, video, video line, selectable pulsewidth,

 

Connect-and-View: Advanced automatic triggering that recognizes signal patterns, automatically sets up and continuously adjusts triggering, time base and amplitude. Automatically displays stable waveforms of complex and dynamic signals like motor drive and control signals.
Video triggering: NTSC, PAL, PAL+, SECAM. Includes field 1, field 2 and line select.
Pulse width triggering: Pulse width qualified by time. Allows for triggering <t, >t, =t, ­t, where t is selectable in minimal steps of 0.01 div. or 50 nsec.
Time delay: One full screen of pre-trigger view or up to 100 screens (= 1200 divisions) of post-trigger  delay

 

Automatic Capture of 100 Screens
 
The instrument ALWAYS memorizes the last 100 screens (no user setup required). When an anomaly occurs on screen, the REPLAY button can be pressed to review the full screen sequence over and over

Recorder Mode

ScopeRecord-Roll Mode
Dual input waveform storage mode
Source and display: Input A, Input B, Dual
Memory depth: 27,500 points per input. Each point consists of Min-Max pair
Min-Max values: Min-Max values are measured at high sample rates ensuring capture and display of glitches
