The UNI-T UPO2104E is a 4-channel oscilloscope for high performance and is a direct successor to the UPO2104CS. Compared to its predecessor, a number of specifications have been changed, for example, the 2104E has a memory depth of 56 Mpts and the waveform capture rate has been increased to 80,000 wfms per second. What makes this scope really unique is that it can use a separate time base per channel. Furthermore, the scope has a large number of functions and the trigger options have been drastically expanded.
