Which oscilloscope to buy?

[naren]

Hi,
I'm planning to create a embedded system design using zigbee
(wireless specification for control applications). I am in the process
of choosing an oscilloscope but am wondering if my choice was correct?
I'm planning to buy the following one from Tektronix. Will it be
suitable for such applications? My intention is to trouble shoot the
circuit board and NOT the ZigBee chip or spectrum. I assume the
chipset I buy is not faulty and just to find out noises, interference,
et. al. in the circuit board.
TDS2022B 200 MHz 2.0 GS/s 2.5 K 2

Kindly advice.
Rgds,
Naren.

Sure, that one will likely do the job as a basic high bandwidth
oscilloscope for troubleshooting.
However, the 2.5K memory is very small, so if you are looking at
decoding data streams or looking at single shot detail on longer
captures etc then it might be useless for you.
If you are doing digital stuff then a mixed signal scope is a better
investment.

If you only need to do troubleshooting and so on I recommend the pico
USB scopes (www.picotech.com)

They are cheap, have pretty decent specs and fill nothing on the table
(no money wasted on display, keyboard etc)
