My first scope

lykkedk · 19th March 2006, 06:30 PM

Hi all.. I got lucky today, caught my first scope.
Planning to use it for meassuring PSU - maybe GAIN / Dissorton whatever...
It's a Kenwood cs-1021 - Anybody got something for it (manuel etc...)

I got some quistion's through.

I need to buy a 'probe' for it : The input BNC say's 1MOhm / 35pF.
// ( I don't care if the probe is used or not, so if you have an used one for sale, I might be interrested.) //

Is there anything I have to consider, buying my probe.

--> Any comment's allowed. - All information appreciated. <--

BTW:I know it's a 'cheap' scope, but I think it's better than nothing at all !

$19.99 Buy It Now 60 MHz probe (1 MOhm) on eBay linked below. Check out his store, great deals on soldering/electronics tools, tweezers, pliers, snips, etc. He has faster probes, but you don't need 'em.

Hi lykkedk,
That's a nice 'scope you have there. It will do most of what you need to do in audio. It even looks like it has a 0.5uS / Div horizonal setting. That means you could use it for setting up CD players easily.

Kenwood is a good brand too, so don't sell it short.

The probe in ebay, dosen't offer shipping to Denmark.

Anyway... It's a good price through.

Hi Jesper,
How much are the original Kenwood probes from the local supplier? The scope is worth using good probes with.

I don't know, but i just ordered one today (~30Euro incl. shipping cost)

The shop, told me, it was fine for my scope.

Hi Jesper,
Just make sure the probe covers the bandwidth of your 'scope minimum.

X1 probes are not suitable, you want a X10 most commonly (you can get X100). The better probes will last longer.

Its a 1x / 10x Allround probe.

You can see it here.

Anyway, I was googling around for a sinwave generator - or simulair. What excatly do i need to messure e.g gain ? Any link for DIY sinusgen. ?

Hi Jesper,
That probe should do you well. Watch you leave it on X10.

Look for something like a Leader LAG120 A or B. Reasonable output distortion. Some of the solid state old HP generators are good too but they may even be more expensive than the Leader. Kenwood may make essentially the same model. Function generators have poor sine wave output, sometimes the square wave isn't very good either. Snag one only if you find it used and cheap, look for a good sine wave generator. The Leader does square waves too.

You can use a CD player with a test CD to generate clean, low distortion sine waves.
