<< < (17/48) > >>

rf-loop:
I do not want to disturb more this very valued deep review thread with this particular small thing so I do niot insert these example images here

Here in other thread can find some my tiny test about SDS1104X-E  AC and DC coupling low frequencies level flatness and AC corner freq (from low impedance source with).

As a newbee I am not sure if this is the right place to post a question about the SDS1104X-E.
I'm considering to buy this scope but what about the acoustic noise of the fan.
Is it acceptable and is there an advise to replace the fan for a quiter one?

Many thanks in advance!

I am the owner of SDS1204X-E so I think I can share my experience.  The fan noise is noticeable but not to the point when I would think about replacing it right now (but may be in future). For comparison - this fan is the nosiest one among 5 running desktops ( I had to replace some of the stock fans with high quality NOCTUA  fans) , 2 RAID towers and 2 UPS running in the same room.  The second noisy one is the fan of APC Smart-UPS 1500.

I also owned SDS1202X-E for 2 weeks, its fan was more quiet. If its really critical for you I can probably measure the noise level using more scientific approaches.

Willem2018:
Thanks for your quick answer!
The NOCTUA fans are selled in the Netherlands so if it is necessary I will replace them.
I own an old 2 channel Agilent 54621A and that unit had a very loud fan I replaced with a silent fan

Again many thanks. :)

There's a really annoying bug bothering me for a while and i'm wondering if someone else experienced it and know if some update is on the way to fix it.

43: Channel is inverted
45: Change the timebase a few clicks and the inverted channel goes back to non inverted, setting still shows inverted.
46: Change the inverted setting to non inverted and nothing happens
47: Change back to inverted and channel is inverted again on the new timebase

would appreciate it if someone knows something.
