My package from Thailand arrived...

...a few days ago.  No, it's nothing illicit.

January stuff

I'm posting this on the day after Groundhog Day.

Checking out the 2430A Tektronix oscilloscope and 2402A Tekmate

Possibly the most intriguing scope of the recent batch is the 2430A.

Checking out the 468 Tektronix Oscilloscope

I powered up the 468 scope today as well.

Tektronix - yes!

I was a baaaaaad boy today.

Tektronix 2225 troubleshooting update

Here it is with both channels grounded, showing plenty of garbage on the screen. Both traces should be completely flat.

Tektronix 2225 checkout and inspection

One of the things that an oscilloscope can do is "freeze" a signal, so that you can look it over and see what the device you are testing is doing.    You can spot normal and abnormal signal patterns if you can visualize the signal.
