Title: 2c42 bandwidth problem [Print this page] Author: fsHantek Time: 2021-4-29 21:52 Title: 2c42 bandwidth problem Edited by fsHantek at 2021-4-29 21:58
I received it this week, but I found out that the bandwidth is very poor, nowhere near the advertised 40MHz.
I attach three pictures.
1. the scope probe was adjusted at 1kHz to give a good square wave
[attach]4331[/attach]
2. at 50kHz the square wave is already distorted
[attach]4332[/attach]
3. at 100kHz even worse
[attach]4333[/attach]
A 40 MHz scope should give good square wave result up to 4 MHz !!
This is max. 500 kHz bandwidth graciously !
Did I get a bad sample?

Hi, what test line do you use to test square wave?
Have you used another oscilloscope for comparison test?
Please give me more pictures to study.
