Ham Radio: Workbench-5 Oscilloscopes, Part 1

THE WORKBENCH – EPISODE 5 – OSCILLOSCOPES Part 1

This week, George and Jeremy are joined at the Workbench by Alan Wolke W2AEW.  Alan is a field application engineer for Tektronix, the world’s most well-known oscilloscope maker.  He also has a YouTube channel that is chock full of great information for those wanting to better understanding oscilloscopes and test equipment in general.  Alan joins us for a two part session to deep drive on oscilloscope features and applications.  In part one, we introduce the oscilloscope, what it’s used for, some introductory concepts, and some comparisons of analog and digital scopes.  We also take a look at probe quality.

 

Due to the length of the content, we will not have our usual news or Q&A sections.  Look for those to be back in a future episode.

Practical buying advice

Favorite models, why?  Price?

KF7IJZ:  Rigol DS-1XXX Z Series:  https://www.rigolna.com/products/digital-oscilloscopes/ds1000z/

Great community support from http://www.eevblog.com/forum/

I own a DS-1104Z-S

DS-1054Z is a steal at $400

KJ6VU:  Inexpensive Used Tektronix or HP Scope, Tektronix 465B

Rigol 1054z 50 MHz, can be software hacked to 100 MHz

 

W2AEW:  Used Tektronix, Hameg, Leader, Kenwood, Hitachi

Don’t buy a service grade scope!

Stay away from Vacuum tube models!

Tektronix 465, 475, 485

Tektronix 2215 (2200 series in general) 2225, 2400 series 2445, 2465

Make sure probes are rated for frequency or greater and make sure compensation range contains the input capacitance of the scope

  1. Another fantastic episode! What an awesome series. I hear at the start of the episode, a concern about the length of the show being too long. We have 14 days between episodes, so please don’t feel the need to “trim too much” out of an episode. If you are talking we are learning 🙂 Thanks for sharing your passion and talents.
