150MHz, 1GS/s, Digital Storage Scope, w/RS-232 Interface

Discontinued Model 5105B

Discontinued: March 1, 2007 MSRP $2,695 / 2 Yr Warranty

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
