Software/Firmware in 6004EU FFT scale is 4x too high
First, I really like my Hantek6254EU-US scope. But I noticed a problem with the cursor value when performing FFT. It is 4 times too large. I can demonstrate it using the built-in 1KHz calibration signal.See the attached screen shot.
Steps to reproduce.
With scope probe (in my case Ch 3) attached to the square wave calibration output lug, press the AUTO button.
Turn off the other three unused channels.
Adjust timebase to 2.000ms / DIV.
Add on screen measurement for Frequency of that channel.
Enable MATH FFT on that channel.
Set the Curstor -> Source -> MATH and the Cursor -> Type -> Trace
Place cursor on peak of fundamental (1st harmonic)
The on screen measurement in my case shows CH3:Freq = 1.008KHz.
But the cursor measurment along the window bottom shows Freq: 3.958KHz, which is 4 x too large.
Perhaps this has been fixed in more recent version(s) of FW/FPGA/SW. DO I have most up to date version?
See attached screen shot
Thanks
