BK Precision 5105B Overview

The model 5105B is a 150 MHz (1GS/s) Analog/Digital Storage Oscilloscope (DSO). It is a high performance 150MHz analog oscilloscope with the capability of digitizing and storing waveforms with its 1GS/s A/D Converters. After the digital acquisition, the data can be manipulated and displayed for examination. Unlike other DSOs on the market the 5105B is an Analog/Digital model that is not limited by the shortcomings of pure Digital Storage Oscilloscopes.

• 1GS/s Real time sampling
• Auto set
• Save/recall
• Readout cursors
• 2 + 2 logic channels
• Time base 50s to 5ns
• 8-Bit low noise flash A/D converters
• Pre and post trigger – 100% to +400%
• Acquisition modes: Single Event, Refresh, Average, Envelope, Roll, Peak-Detect
• On screen Help information
• RS-232 Interface Advantages of Analog over Digital:
  • Analog scopes display signals in real time
  • Analog scopes can catch rare events that DSOs can miss due to their sampling rate limitations
  • Analog scope are not limited in vertical resolution by 8 or 12 bit A/D converters that can lose signal details during the digitizing process
  • Analog scopes have a frequency response which closely follows the Gaussian curve; this means in practice that frequencies far beyond the -3dB frequency will be shown. The amplitude will be reduced but they will be shown
• Advantages of the added digital operation:
  • Capture and storage of single events for event analysis 
  • No screen flicker with very low frequency signals
  • Fast signals with a low repetition rate response and low duty cycle can be displayed with high intensity
