Model 5105B
150 MHz Analog/Digital Oscilloscope

Analog -  30MHz W/ 50MHz Frequency Counter | 30 MHz | 40 MHz | 60 MHz | 100 MHz
Digital - 20 MHz Analog/Digital | 150 MHz Analog/Digital | Selection Guide | Oscilloscope Pricing

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 to digitize and store 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.


5105B Features:

  • 1GS/s Real time sampling
  • Auto set
  • Save/recall
  • Readout cursors
  • 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 scopes 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.
  • There will be 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
