About wfps for Owon SDS7102.
Guys I'm not an expert, but If I connected the trigger output (P/F) of Owon to a multimeter like Fluke45 at Frequency Postition, can you tell me what really measures with that? Is this appropriate for wfps measures?
If it yes, then Owon measures from low 10Hz (10M) to 450Hz(1K).
And on what timebases do you measure these frequencies? If you'll recall, in Dave's video, he has a frequency counter hooked up to the Trigger Out, and he can never get it to read more than 35Hz - regardless of the sample length.
Yeap "marmad" I have seen the measurement with the Agilent Frequency Counter that Daves presentated and for that reason I''ll tried to do same with my multimeter a Fluke45.
I don't want to prove something but it was my curiosity and for this reason I asked Daves what fw has the SDS9302.
My Owon is SDS7102V with 12118XX serial number and the last 3.3 patch fw.
I have try the following test in two Fluke45 multimeters (Frequency position, 5Hz-1MHz), this video is from the newer of them.
As I told many times, I don't speak the english language well and of cource in this video I don't try to speak!
At the begging of video I have attached the generator output (Hameg 10MHz function generator) to the Fluke and test the accuracy of frequency at three different frequencies, at the last I choosed the 0.98MHz (cause 1MHz limit of Fluke45) because Dave's test was with 1MHz frequency.
I zoomed between oscilloscope screen and fluke screen because my video isn't a HD. The video with Fluke and Owon at the same image isn't clearly! For that reason I prefered a zoomed area, now the interesting areas are clearly!
I started with Memory Depth of 1K, with almost all time range of oscilloscope and keep this method of presantation to the others 10K,100K, 1M (I jumped this), 10M. All the time the Fluke demonstates the frequency capture.
Initial the capture is for Ch1 (activate), Ch2 is deactivated. At the end, I activated both of them (measuring at 1K) because I saw that Frequency of Trigger Output is increased with both of them.
I know that Fluke45 isn't a Frequency counter but has a Frequency measurement function. If I connect the Trigger Output (TTL) of Hameg generator to Fluke45, it measures the frequency output of genarator (at my example 0.98MHz). But here what measures really the Fluke from Owon?
