I recently upgraded from an SDS1104X-e to an SDS2104X HD.
Haven't put the 2104 HD to any serious use yet, but the FFT looks really nice.
Today I wanted to compare the waveforms on the 1104X-E with the 2104X HD.
The results are shocking to me (meaning how bad the 1104X-E is...), or am I doing something completely stupid.
Preconditions:
The signal generator is a cheap ebay ADF4351 based board at 35 MHz.
The 1104X-E is un-un-locked
i.e. 100 MHz bandwidth. 100 mV/div, full bandwidth.
Connected to the signal generator and shares the signal via a T piece.
The 2104X HD is upgraded to 200 MHz. 100 mV/div, full bandwidth, 50 ohms input.
I have previously checked the -3dB limit of the1104X-E and it is about 120 MHz, so I am excluding use error there.
The amount of detail on the 2104 HD compared to the 1104X-E is shocking to me, or am I doing something seriously wrong?
Any feedback is very welcome.
