if you goto http://labvolt.com/product.asp?id=163&Line_Id=64 they do have a
device there to convert an ordinary scope into a somewhat crude spectrum
analyser ( i believe it maxes out around 127Mhz), but im not sure if they
sell that device seperatly, and the whole Fm/Am training suite which the
link goes to is around $250,000 CDN.

I would buy both of them. An oscilloscope is something you really need
for doing signal tracing, etc. while a spectrum analyzer is a must if
you are doing synthesizer/oscillator/transmitter design. I have both
of
them and use them all of the time. Other good things to have are an RF
power meter, modulation meter, frequency counter, broadband noise
source, RF generator, DVM, VOM, and a good variable power supply. This
just scratches the surface, depending on your needs.

The choice between the two depends on what you are most interested in
doing. Since both these instruments are designed for different tasks.
However if you are looking for a good all purpose Swiss Army knife sort
of
tool for general ham useage, I would look at a gadget called a service
monitor. Depending on make and model, you can find one that combines the
features of most of the instruments on Pete's list They usually have
a
scope that will do af and also act as a spectrum analyzer along with
power
meters,signal generator,frequency/modulation meter perhaps a DVM etc.
All
in one handy dandy portable package.

Here is an example of one of the many on Ebay at present.

As a general purpose test and troubleshooting tool I find these hard to
beat!!

I already have a scope which I use on my work bench, but it sits a lot
not being used, so it would be kind of handy to plug in a device which
would enable it to be used as a SA or panadapter type scope for the
shack. This would make my scope much more useful. Anything like that
around?
