Download Digitizing Oscilloscopes (2009)
Transcript
University of Saskatchewan Electrical Engineering Laboratory Equipment Manual There is one last important point to be made about the digitizing oscilloscopes. They all have coaxial connectors (known as BNC connectors); they consist of an inner conductor and an outer conductor, which is connected to ground internal to the scope. When you connect a scope to your circuit with a BNC-to-alligator clip cable, remember that the red clip is the signal connection, while black clip is ground. Wherever that black clip is connected will be grounded! In terms of functionality, that’s really all there is to the operation of an oscilloscope. What is more difficult to remember is where the controls are on all of the different oscilloscopes, and where to find the specialized functions such as the “x vs. y” display mode. The specifics of each oscilloscope in the lab now follow. HP 54600A/54601A 100 MHz Digitizing Oscilloscope • • • • • Repetitive Bandwidth – 100 MHz 20 MSample/s 8 bit A/D 2 channel (HP 54600A) / 4 channel (HP 54601A) input and display Vertical sensitivity range 2 mV/div – 5 V/div Horizontal sensitivity range 2 ns/div – 5 sec/div The HP 54601A, is really just a two channel oscilloscope. The two main channels are channels 1 and 2, with channels 3 and 4 being auxiliary or reduced performance inputs. Each input has an input impedance of 1 M# in parallel with a capacitance of $ 13 pF. Each input may tolerate an absolute maximum of 400 V. The HPIB connector is found on the back left side of the scope. Revised: Sept. 2009, J. Kowalski Page 2 of 25
