An oscilloscope is a piece of electrical test equipment which allows you to visually see an electrical signal shown on a display. We have two Hameg HM203-7 oscilloscopes at the hackspace.
A basic oscilloscope specification is given below:
- Analogue Cathode ray tube (CRT)
- Bandwidth: 20MHz
- 2 channel + Ext trigger (2.5:1 to 12.5v/div)
- 5v to 5mv vertical (x5 giving 1mv sensitivity)
- 100ms to 0.2us horizontal (x10 to give 20ns/div)
- Component tester
- X-Y mode for Lissajous figure and drawing funny images with audio!
- Scope 1 issues: [31 March 2016] Functional. CH1 10% low on vertical, CH2 10% low on vertical, Horizontal about 5% high, confirmed against cal point and a precision v ref.
- Scope 2 Issues: [31 March 2016] Functional. CH1 10% low on vertical, CH2 10% low on vertical, Horizontal about 5% low, confirmed against cal point and a precision v ref.
- Manual TBD
- Owner: Fligg, labelled scope 1
- Owner: TBD, labelled scope 2
The spaces oscilloscopes will NOT normally have a calibration certificate. Most will be well outside their calibration date. Having said that it is common to perform a basic oscilloscopes calibration check before each use against a known calibration source to confirm it is suitable for use. Most oscilloscopes have a calibration signal output point on the front panel. Some have rear panel outputs.
Ask on the mailing list for volunteers to demonstrate the use of any of the test equipment.
