New Oscilloscope – Siglent SDS 1202X-E

Since I’m going to be here a bit longer I decided to get a new oscilloscope. I pushed the “Buy It Now” button while receiving my third chemotherapy treatment this past week so some of this might have been drug induced.

I’d actually been hemming and hawing for a bit over a year about getting a new oscilloscope. It’s a Siglent SDS 1202X-E. Prior to reading the posts by John, AE5X I had been considering a Rigol DS1054Z but John’s posts persuaded me to choose the Siglent. It just arrived yesterday and thus far I’m pleased with it.

What’s in the box?

The scope comes well packed and is much smaller than I anticipated.

Included with the scope are the power cord, a USB cable, two 1X\10X probes, and a quick start manual.

Probe accessories

Each probe includes colored ID rings, a BNC adapter, tip shrouds and a compensation adjustment tool.

For years I’ve used a Tektronix 2215 and it has served me well. For whatever reason, on occasion I’ve wanted to capture a waveform but the only way to do it was to photograph the display. It reminded me of the days of using a Polaroid camera on the old Tektronix scopes that we had in the R&D lab in which I worked summers when I was going to school. Then we obtained some Nicolet Instruments storage scopes. Suddenly no one wanted to use the old Tektronix Polaroid option.

Now you could save a whole waveform on a 5.25 inch floppy. (And if I recall correctly it was one capture per disk.)

Things have progressed quite a bit since those days. This Siglent has an amazing amount of features for the price. I expect that it will serve me well for a number of years. Now off to capture some waveforms.

 

The second best Christmas present

My wife and I were at the Mayo Clinic this past week for some doctor appointments and the third round of chemotherapy. The first appointment of the week was a PET scan. The external indicators plus lab work indicated that things were progressing in the right direction but the doctors (and my wife and I) wanted the internal view.

Tuesday afternoon we got the results from the PET scan and it is all clear. The areas of concern from the scan prior to treatment are all gone. The doctors call it complete metabolic remission. (Dark areas except the brain and kidneys were areas of cancer.)

Obviously we are overjoyed at this result. We had hoped and prayed to hear this after the sixth round of treatment. To hear it after only two rounds is the second best Christmas present of all.

We need to finish up the rest of the chemotherapy to be sure that everything is gone in order to decrease the risk of it returning as there is a 40-50% chance of it doing so.

So what’s the best Christmas present of all? The Reason for the Season.

And there were in the same country shepherds abiding in the field, keeping watch over their flock by night. And, lo, the angel of the Lord came upon them, and the glory of the Lord shone round about them: and they were sore afraid. And the angel said unto them, Fear not: for, behold, I bring you good tidings of great joy, which shall be to all people. For unto you is born this day in the city of David a Saviour, which is Christ the Lord. And this [shall be] a sign unto you; Ye shall find the babe wrapped in swaddling clothes, lying in a manger. And suddenly therewas with the angel a multitude of the heavenly host praising God, and saying, Glory to God in the highest, and on earth peace, good will toward men. Luke 2: 8-14

We have much to be thankful for this Christmas. More than any Christmas past.

May your Christmas season be filled with joy in the Reason for the Season.
