Involvement:Expert (understands the inner workings) - Ownership:1 week to 1 month
shows OK up to 100 Mhz digital signals,
menu is quite intuitive
(though reading the booklet is a must for some
functions). The PrtScr button is a very quick
way to get screen snapshot (settings values
are shown nicely in same snapshot).
1. The PC connection is not functioning at all:
It came with CD with Chinese letters in file
name, failed to install. I downloaded the app
from UNI-T site, it opened, even showed the
scope is connected, but nothing functioned
(except a few knobs that turned around by
my mouse - the rest stayed grey).
Note it prevented me from verifying memory
depth (cannot get the recorded signal into a
file to check the ability to post-process)
2. The screen is stated as 800x480 pixels.
The snapshot provides a 400x240 BMP file. I
suspect that the system resolution is half of
the actual display and of the promise in spec.
(probably memory / SW lack of support ?)
3. A few more minor "expectation gaps"
found comparing the user manual to the
scope (e.g. missing "Video" "ALT trig" and
"EXT/5" options in trigger menu)
[ FYI The Model and version I checked is
UTD2052CL, HW ver 2.00 , SW ver 1.09 ]
4. For a person used to work with top of line
D.S.O's, main feature I miss here is smarter
trigger (especially smart pre-trigger chain,
e.g. rise at channel 1, delay or events of of
at least ... , and another rise on same
channel) note that real power is achieved
with 2nd channel and 2nd trigger level -
requires more HW, maybe some
improvements could be added just in SW)
5. BTW I want to believe PC SW issue will
be resolved. But if one builds expectations,
then note that the SW offers only manual
operation via GUI (mouse +KBD), while the
"ultimate" testing needs the ability to access
the PC SW from your own tester program
(through FTP / ActiveX / ect...)
At the time being, I believe it is the best
standalone scope for its price, especially if you
just want to see signals up to ~100Mhz and do
not really need more than keeping snapshots of
