New Osmelloscope (... oscilloscope) Tek TDS420A
While trying to work on my RL02 drives, I realised that my Farnell 20MHz scope is terrible, and measurement taking is likely wrong. After a recommendation from a friend, I found a nice Tektronix TDS420A on eBay for about £300. A bit expensive, I thought, but when compared with a new Rigol, for example, it's actually a good deal.
Here are the rough specs:
- Four channel
- Enabled Options:
1M120,000 Point memory
2FAdvanced Digital Signal Processing math
Here is a photo of the TDS420A:
One of the nice things about this scope is that I can save the waveform over RS232 to my PC. Here's an EPS which I have turned to a PNG:
I generated this with a straight through RS232 cable
cat /dev/ttyUSB0 | tee out.eps
I'm using tee instead of a redirect so that I can see when the transfer has finished.
