Hello, this is my first post in this forum after several weeks reading. Really a great community!
As result, and after studying all available information, I also became a happy owner of SDS2000XPlus. Many thanks to all members for your great help in this process. My idea was to share my first impressions.
The scope really feels like scaled-down SDS5k. I like rich measurement functions including statistics, comfortable cursors, and intuitive parameter control with Universal knob. Shared channel control, compared to separate channel control in SDS5K, is no restriction to me. I do not change channel parameters that frequently.
Probe sensing on channel inputs is compatible with TEK probe, seems only one probe attenuation is implemented: 10x. When changing probe sense resistor values according TEK spec, scope does not change the attenuation value. Probably only single-level comparator implemented in the scope.
The trigger on input channels works perfectly, external trigger input has some jitter in ns-region. No issue for me.
Bandwidth evaluation confirms high-grade components used. I look forward to see the first tear-down report! Attached see the channel bandwidth comparison of different 100MHz and 500MHz models. The -3dB bandwidth is 150M and 600M respectively, with some variations between units. Many thanks to other’s contribution.
I compared the 500M model rise-time in three setups: Leo’s pulse generator only, Leo + TEK 500MHz passive probe and Leo + TEK 1GHz active probe. Measured rise-time is 650ps for Leo, <1ns for passive probe and <700ps for active probe. Very respectable values.
Siglent family includes more attractive products. Large output voltage and low jitter on AWG and good price/performance ratio of spectrum/vector analyzer catch my attention. I wish more unified design and operation concepts as power on/off switches (some have soft-switches, others not), menu structure and button labeling and layout to be found in new products.
I really recommend the new SDS2000XPlus to all interested readers.
