I am in the market for a general purpose oscilloscope for around the house
trouble shooting (TV's, stereos) and serious experimentation on TTL, and
microbased circuits that are from .01 to 20 MHz. So it looks like I could
use a 100MHz scope and found there are quite a few available. Of the many
I have looked at the following are the current contenders (in order of
increasing cost)
B&K - Pretty cheap at $995 but also feels it too.
Hitachi V1050F - some what nicer at $1685.
Kiksui (sp?) 6100 - which is real nice at $1995 with simultaneous viewing of
regular sweep and the delayed sweep. Plus trigger view and some others.
Tektronix 2200 series (2215 probably) - Has a good name behind it but I have
heard some disappointed comments from people who have used them.
So the call goes out, if you have used one of the above or some other 100 Mhz
scope that had delayed sweep and a reasonable sized screen (NLS doesn't count)
and it retails in qty 1 for less than $2000 I would be interested in
hearing your comments pro or con.

My first decent scope was a used B&K 1472, a 30 MHz
unit actually manufactured by Trio. Its performance
and quality of construction were very satisfactory.
Perhaps some of the newer B&K models aren't built as
well. The newer Hitachi and Hameg scopes don't have
the same quality "feel" of the older B&K.
I later upgraded to a 60 MHz Tek 2215 scope and have
been satisfied with it. My 2215 was an early unit, and
was modified for free by the local Tek field service
office within the 1 year warrantee period with all
updates, including a modification to the switching
power supply unit to reduce audible noise and RFI. The
only feature I miss on the Tek 2215 is the lack of
switchable input filtering (e.g. HF reject, LF reject,
etc.).
A lot of money was saved by buying the B&K used,
although I reluctantly paid list price for the new Tek.
I always wanted a Tek, and there was no way to buy a
new Tek or HP scope without paying list price plus tax
(in Illinois).
Although I don't get as much use out of the scope as I
thought I would, there's just no substitute when I do
need it. I built a 550 - 1650 kHz band reject filter
using hand selected components. Having a scope and a
sweep generator allowed me to measure filter charac-
teristics as I tried different capacitors from my junk-
box.
A good technician can use a scope for many measure-
ments, but I still haven't broken away from using my
trusty Fluke 8024B DMM and solid state VIZ Master Vol-
tOhmyst.
Having the proper equipment, and several cans of cir-
cuit cooler spray, gives me the confidence to take in
the "tough dog" repair jobs, like the Drake R4C ham
receiver that the factory couldn't or wouldn't fix (an
flakey product detector caused by a cold solder joint
on the BFO transistor).
