Main thing is I want 4 channels, intensity grading with an MSO option - so we'll see.
Some interesting stuff
in the data sheet for the upcoming MSO4000 series (if you want to Google Translate Chinese):
Here are some specs for the Digital channels (
lots o'memory - up to 28M per channel):
Digital channel sampling rate 1GSa/s, memory depth per channel up to 28Mpts standard
Digital channel waveform capture rate of 85,000 wfms/s
Support hardware real-time digital channel waveform recording, playback, recording a maximum of up to 64,000 frames
Supports analog and digital channels mixed triggering and decode
Convenient digital channel grouping and group operations
Support for multiple logic levels
Time-correlated analog and digital channels are displayed waveform
Real-time sampling rate: Digital channels: 1.0 GSa/s
Peak detection: Digital channels: 1 ns
Minimum detectable
pulse width: Digital Channel: 5 ns
Memory Depth Digital channels: Max 28M Point per channel
Threshold: 8-channel group 1 adjustable threshold
Threshold Selection: TTL (1.4 V)
5.0 V CMOS (+2.5 V), 3.3 V CMOS (+1.65 V)
2.5 V CMOS (+1.25 V), 1.8 V CMOS (+0.9 V)
ECL (-1.3 V)
PECL (+3.7 V)
LVDS (+1.2 V)
0 V
User-defined
Threshold range: ± 20.0V, 10 mV steps
Threshold Accuracy: ± (100 mV + 3% of threshold setting)
Dynamic Range: ± 10 V + threshold
Minimum voltage swing: 500 mVpp
Vertical resolution: 1 bit
