The Basics
An oscilloscope is a piece of electrical test equipment which allows you to visually see an electrical signal shown on a display.
Specification
- GW Instek GDS-820S
- Digital storage oscilloscope (DSO)
- 2 channel
- Real Time sample rate: 100MS/s maximum on each channel
- Equivalent Time sample rate: 25GS/s E.T. maximum on each channel
- Bandwidth: 150MHz effectively an equivalent time bandwidth. So not strictly speaking an 150MHz scope unless you are talking about the equivalent time sample rate on a repetitive signal.
- 5.7 inch mono LCD (320x240)
- FFT, 125k/CH
- RS232, USB and GPIB
- Trigger DC-30MHz for 0.5div or 5mV, 30MHz to 150MHz 1.5 div or 15mV
- Issues: Faulty needs repair. No boot. Power board was repaired previously. The firmware was reflashed and unit previously worked, but is now not functioning. Try re-flashing.
- Manual: TBD
- Owner: Fligg
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
Unless you are very experienced with an oscilloscope then it is not advisable to probe high voltages or high power sources. It is possible to electrocute yourself or damage the oscilloscope. Special oscilloscope probes and specific connection methods are needed for probing high voltage and mains electricity signals. The oscilloscopes are replaceable, you are not! We want you to be safe.
Oscilloscopes can be heavy instruments. Bend at the knees when lifting and ask for help if you find the instrument too heavy to move.
Do not leave oscilloscope probes (or any wires) hanging over the edge of a bench or on the floor. You will stand on or trip over them.
