sible. With this arrangement,
you have an easy-to-build wideband matching circuit without transformers.
The loss is 4db which can be accounted for when you calibrate the SA.

Hi Tom,
One major source of noise is the CRT monitor. It helps to make the screen
display as uniform as possible, like a blank window or a plain background
without texture.

Digikey (digikey.com) is first-rate.
I use Digikey and Mouser for almost everything. Sometimes there is a
noticeable difference in their prices but usually they are similar. Here in
Dallas, I get stuff from Mouser in less than 24 hours. Digikey takes 3 or 4
days.

Hi Wayne,
That's sounds very interesting.
What frequency range and resolution would you like to have in the spectrum
analyzer?
What dynamic range is required for it to be useful?
Other specification?

connected. This may be hard to see. A fillet is easier to
inspect. If the height of the lead sticking out of the board is critical,
it's no extra trouble to trim the fillet along with the lead.

Hi Robert,
This looks very interesting!
Do you have any details available on how you constructed this station?
Are you interested in making more of them to sell? With the proliferation
of SMDs now,
I bet a lot of people could use something like this.

for $4 or $5. If necessary, use solderwick to remove bridges between the
leads. This leaves enough solder to still form a joint
between the lead and the pad. When using the liquid flux, I haven't had trouble
with bridges, even on 25mil pitc
charge. I experienced damage
once with only a six foot length of coax.
Always short a open transmission line before connecting it to your rig.

This assumes the micro does power up correctly so it can initiallize the
watchdog timer.
Later if something goes wrong, it can issue a software reset. This is also
good for recovering from
very rare and almost-impossible to catch software "issues".
