communication of oscilloscope with a computer

Hi!
I have a Tektronix TDS 220 oscilloscope and I'm intrested in checking
Audio-Video synchronization from DVD. I succseeded doing it manually
with the oscilloscope, but I am intersted in doing it automatically.
Is there a way of communication of the oscilloscope with the computer
(I saw there is a COM PORT at the back of it...)? Which software or
hardware I need for it?

Download the programming manual. If they don't have the exact one
online, you should be able to find one close enough.
If it has gpib, you can get a lot of stuff at www.ni.com.

COM ports only transmit data quite slowly. It's a control interface not a
data interface. If you're thinking you can send the trace data via a COM
port - you're mistaken.

It's quite possible to transfer the waveform over the RS232 port.
Curve command or something. Or set the RS232 as output for hardcopy
and ask for a hardcopy, which prints the entire screen, including
settings and graticule etc. It is relative slow of course.

"relatively slow" is relative. Compared to looking at the screen and
picking points off and entering them into the compute, the RS232 is
blindingly fast. It also is very good when you need to acquire many shots
of the data and process them to see if the answer is right.

Tektronix sells Wavestar, that allows communication over RS232.

This allows screen and settings capture in one direction and set-up of
the display/measurement settings in the other.

There are legacy com packages that can perform thesame thing without
the elaborate windows GUI. Some are listed in the downloads section
for your model of scope. These may be harder to locate since the model
was discontinued.

Hi Klaus!
Could you please post the code for using USB-Serial you talked about?
I don't need it to be fast anyway...
Thanks, Karina

Yes, I have an application where I use my TDS220 and a function generator
(HP33120A) to perform a crude gain/phase network measurement. But ofcourse
its slow, takes a couple of seconds to get an entire trace

I can post the code if you are interested - it is adapted to use USB to
serial converters, so it's even slower than "normal" RS232

Cheers
