We are attempting to use the DHO814 for Transistor Curve Tracer utilizing the XY Mode. Really like the display that includes the X and Y numeric labels, but can't get the display to show enough brightness in XY mode (we have brightness set to max), it's fine in regular Time Domain mode tho.
The results are very faint as shown.
The setup is an AWG used to sweep (0-8V) the X Axis thru a Resistor (Collector 100Ω) and the DSO CH1 connects to Resistor, the AWG other channel is stair-stepped (8 Steps 0-10V) thru a Resistor (Base 50KΩ). Another Resistor (Emitter 10Ω) and DSO CH2 is connected across this resistor to display Current on the Y Axis.
You can see the Siglent DSO displays the result with good brightness while the DHO814 we can't get to display with sufficient brightness.
BTW wish the Siglent would include the XY display numerics like the Rigol, they are nice

Any help is from the Rigol gurus is appreciated.
Best
