LP142 Technical Specifications

General Features

• Compact and Portable: At 6.6 lbs (3 kg), this compact scope is easy to carry and fits very easily onto crowded workbenches.
• High-Speed Sampling Rate and Long Memory: Operates at 500 MS/s sampling rate with 100 MHz analog bandwidth. Each channel has a long 100 kpoints acquisition memory.
• High Accuracy: Vertical accuracy is within 2% and horizontal accuracy is 50 ppm (0.005%).
• Cursor Measurements: Two cursors (two vertical or two horizontal) let you measure voltage difference (delta V), time difference (delta t), frequency (1/delta t), and V at t for a specific waveform.
• Auto Copy: Display or waveform data can be output automatically to a specified device (built-in printer, ATA card, or floppy disk).
• Simple to Use, yet Powerful: Features a variety of automatic measurements, triggers, floppy, internal printer, and interfaces to external devices.
• Great Value: Lots of information at an amazingly low cost!

• Easy-to-Use Menu Selection: Just turn the function knob to select a menu item, then press to activate it.
• Help Menu: Explains the various menu functions. Useful for beginners or for advanced users needing to know what a particular function does.
• Event Trigger: Wide range of triggers, including event triggers (count/burst/extra/missing) and TV triggers (NTSC/PAL/SECAM).
• Hardware Five-Digit Frequency Counter: Input signal frequency can be shown in five digits. No more guessing about signal aliasing.
• 13 Automatic Measurements: All the basic automatic functions required for common measurements are provided, assuring quick, accurate results and improving working efficiency.
• 25 GS/s Equivalent Sampling: Using the equivalent sampling method, the time resolution is increased up to 40 ps (equivalent to 25 GS/s). Pre-trigger information is available.
• Input/Output Devices:
