Then again, $1636 is getting very serious indeed. Wish we had more user feedback on the Instek lineup.
OK, to put this into perspective:
To get the battery option on something like the TDS series, you need to go to the Tek TPS series. You get the battery and, to my mind, an unneeded mem card slot, SD card I think. For $3200!
The Instek, if you get the coupon deal, is $1638 + the $385 battery (factory installation only), $2021! The difference between them: 3200 - 2021 = $1,179! Half the cost of a TDS model! I haven't factored in tax, which is less on the less expensive unit, natch. You can go to the link I provided and find a link to the manual for the Instek unit. Read up! You'll be impressed!
As I read the Instek manual, I was struck how close their manual ran to the Tektronix manual for the TDS-2024B I had. The only obvious weirdness was in the memory allocation.
The TDS claims 600 points per channel in their brochure, the specs, and at the start of the manual. At the end, though, in the details section, it says less points are used at the highest two or three speeds. It states that less points are used, and algorithms are used to fit the data to the display.
The GDS says it uses 500 (less than the TDS), 5000, 12,500, or 25,000 points! This is a He** of a spread! The user can configure memory usage for one, two or four channel collection, and sweep settings have an effect on these numbers. Look this up on page 105 of the .PDF of their manual.
If I didn't already have the Tek I would go for this beauty. I may spring for this unit and sell off my Tek to defray the cost. My Tek is not a year old and the warranty is three years and transferable, hardly used, still in great shape, I even still have the box it came in. It will probably go on Ebay.
Any takers?
