BK Precision 5105B 150MHz (1GS/s) Analog/Digital Oscilloscope 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.

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
