'[EE]:Oscilloscope GW Instek GDS-820C experience'

Hi,

I bought this GW Instek GDS-820C digital oscilloscope.
To my surprise it was extremely difficult to use in daylight.
The screen raster was next to impossible to see at 100%
contrast. I subdued afternoon light it was OK but even
when the room was rather dark, the display "disappeared"
at around 40% contrast. Has any one any experience in
this?

In the light level I refer to there was for example no problem
to distinguish the old TDS 220 b/w,  the laptop screen (color)
or the mobile phone (color ). I returned the GDS-820C to
the supplier and ordered another brand instead, but I sort of
liked some of the features it has. Relatively long memory a.o.

Regards,
PerL

I have a GDS-806S (monochrome) and I can see it fine. Wouldn't it be a
problem with that specific unit?

I have a 17" LCD computer monitor that I can see perfectly, a color LCD of
the cell phone, that also can be seen under the current light circumstances.

The LCD contrast is... It does not have an indicator, but I can't generate a
contrast situation in wich I don't see the screen.

Bye!

You know, you make me wonder... I just took my scope out of the office and
checked that I can see the screen perfectly, even under direct sunlight. It
cant be seen, only when the sun is reflecting on the screen :)

I think that your scope screen was the problem, check another one.

The new Tektronix TDS2022B, which unfortunately costs  50% more
and has 50 times less memory. 2.5 K as opposed to 125 K.

And less features, right? Why don't you give the INSTEK a new try, really, I
have mine for two years now.

The memory part can be fixed using a PC. The TDSxxxB
has USB which allows the scope to display the signal
to the PC. I believe there is logging capability in
the software itself.
