BK Precision 5105B - 150MHz, 1GS/s, Digital Storage Scope, w/RS-232 Interface

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.

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
