== The Basics ==

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. 

== Specification ==

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 [https://www.youtube.com/watch?v=rtR63-ecUNo 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



== Calibration ==

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. 

== Induction ==

Ask on the mailing list for volunteers to demonstrate the use of any of the test equipment. 

== Safety ==

[[Electronics/safety|You must read the safety documentation in this link before using this equipment.]]
