On https://www.siglent.eu/Downloads I see the release date is still 2015. Should I look for other sources?
Here's the link for the latest FW for 60,100 and 150 MHz models.
https://www.siglenteu.com/download/6166/Be sure to carefully read the firmware install instructions as there's a cfg file that needs be installed too.
Here's the changelog:
1. The probe attenuation factor is considered in the trend diagram mode.
2. Digital filtering state remains even in scope stop state.
3. The switchboard can record the configuration of the math waveform.
4. The Math waveform takes into account the probe coefficient configuration.
5. Improved Win10/EasyScope connectivity.
6. Improved vertical cursor measurements when changing scales on fixed/stopped waveforms
7. Enabled self-calibration under Normal or Single mode.
8. Improved edge trigger performance for single and normal mode
9. Increased Single trigger data depth in long storage mode(from 20kto2Mpts).
10. Increased stability of trend map transfer of CSV data to USB memory devices > 4 GB
11. Optimize the display algorithm of multi-meter trend chart and oscilloscope trend chart. Solves the slow response of keys after long recording time.
12. Enhanced FFT data usage. Long storage features 40 times the corresponding frequency points used in ordinary storage.
13. Improved read/write timeout to the U disk.
14. Time stamp information added to the saved CSV file.
Thanks for the advices, I was more concerned for the safety of the instrument
In fact, I understand well that if a ground clip is connected to live, also the other ground clip will be connected to live (exactly as you stated with floating a bench oscilloscope and connecting its ground to live: all the chassis would become live). Since in this models there is no exposed metal part, if you leave it floating as it should be (without usb cable connected for example) it should be safe, do you agree?
Yes, agreed but there are other potential sources of connection to the live chassis. Probe Cal and USB.
Just be careful and properly think risk through.
I don't have an SHS model now so I can't check these issues but rather just link them through to Siglent for them to properly investigate.
