Sorry to hear about your job. Im sure its just a sign of better things to come. Great video. The last time I tried I was having issues getting q pulse on the SG-003A to output consistently. Ill have to try it agin this evening.
Thanks, just picking up odd jobs at the moment. Q-Pulse seems pretty consistent when I was testing, I know you have been having troubles with your units though.
I just figured out I wasn’t pressing the play/pause button to get it outputting pulses. It was confusing me at first because when you press on/off without pressing play/pause it outputs a single pulse. Im glad you made this video. It definitely helped me figure out what I was doing wrong.
Haven't seen a video of yours in a but, sorry to hear about the job. Great video on the Q-pulse function. Just got a new scope (Hantek DSO2D15) and was using the SG-003A to make some waves. I don't recall the square waves being so messy though. But could be your lead set up, the actual flow meter had nice square waves. Maybe just the generators are lacking a bit or leads undercompensated not being an actual probe. Unrelated, but as far as the scope I just got, I can't recommend it. Seems to freeze up often, which a power cycle normally fixes. But two days ago it wouldn't reset after power cycling. Only a few buttons would work and luckily I was able to load some script in to it via USB to detect a certain power cycle sequence to initiate a factory reset. Which got it working again. But prior to the script I spent a few hours loading up software to try and reflash the FGPA from a windows machine. It was close to flying out the window and being done with it. Long story on actually getting one too. Hoping they release new firmware to fix it, but looking up the history, it's had a lot of firmware releases. It's inexpensive and willing to lose some accuracy, but freezes and almost bricking it, no. Anyway.....
Could be I am picking up some noise from a surrounding source, but I don't get noise when measuring the output of a waveform generator using the same lead, either 50 Ohm terminated or unterminated. Shame about the new scope, I have never really looked at much of the Hantek equipment. I do have one of their data loggers around somewhere that I brought for a specific task but never really got it to work that well. Like you say, hopefully a new firmware will be released to address the issues. Thanks for watching and commenting.
I reckon you can manually toogle them one after the other? when in stop-mode/active if you hit the up button (button preset) instead of hitting play/curve button that makes it automatic. hit the "up button" here 2:30 (step up sign) Thx for the video +1 I really appreciate that you dig into some of the deeper features on these process / signal gen meters, as they have quite a lot features up their sleeve. Only got the SG003A and still trying to wrap my head around what the different things, actually do... likely need to dedicate some time to the manual or watch more of your videos as you have way more knowledge on the subject then I have... though already a subscr.
Thanks for watching and commenting. Yes on the Fnirsi units, I went back and found that the up button gives a single pulse with each press. The right button gives the full run of the pulses and found that the down button stops and resets back to the number of pulses entered without using the on/off/enter button. On the MR9270S+ I can only get the up button to run the pulses and the right button to send out a single pulse. Thanks for the information.
@@three-phase562 yep, also what I noticed. you can also adjust the timebase on the fly by hitting "out" while its running its cycles, and the timebase seems to be spot on my scope, and 0.1ms cycles between 99.99us and 100.0us (Micsig STO1054C) you can also somewhat automate the manual cycle by holding the up-button, but it seem to double the sparetime in between cycles. and you can obviously also hit the "graphing menu" in Q Pulse usecase with FN+curve and it will plot out the cycles with a falling graph-line and visualize it with a couple of axes, that I recall you do have soem control on those axes, and if it shall zoom in, or out and likely interval. FN+out and setting gear symbol, graph.. - and the control button-scheme is the same in the Graph/curve-screen, so all the same things can be adjusted, though the symbols are smaller, so likely not that ideal for video purpose.. Though my SG003A seems to be a little tricky in Q Pulse, as sometimes the first cycle is a weird short fellow and other times it aint and match my ms setting...maybe its the triggering on the scope. What usecases does the switching feature holds? 0:46..switching obviously, but cant really make heads or tails when looking at it on the scope, while on the SG003A graphdisplay it plugs in a segmented line, as it cycling down. (10ms) the scope shows some very fast spikes up / down.. arhh I see there seems to be 10ms betweeen these very fast up spikes, and 5ms between up to a down spike and the voltage adjustment on SG003A doesnt seem to influence. fair enoug Either way, great video, always a joy when one can follow suit and test it in own regi and trying to comprihend what the different things do, and the usecases they could be handy in..
@@JAKOB1977 Yes, there is a lot of functionality built into these units and it takes a while to figure them all out. I haven't noticed any issue with the output pulse width on my SG-004A, they have all been equal across the waveform. I would need to go back and take another look to be certain though. The switching function is for use when your input has either a pull up or pull down resistor wired to it. So particularly useful for TTL / CMOS logic inputs. As it is a transistor switch, it can be used in place of a mechanical switch to avoid contact bounce affecting the input signal.
Hello, ragarding the Q-Pulse issue of the Mr signal unit, have you tried to contact them if there is a firmware update to fix it? Great Video series on these devices by the way 😊..
Hi, no I have never contacted their technical support. They have a firmware update program I downloaded, but could never connect to the instrument with it. Thanks for watching!
This was a useful video. Also the other videos you made. Thanks for that. I have another question about the pulse output. Is it also possible to output a pulse of 3V or 12V to a measuring device? Or something in between 3 and 12V? I want to simulate a pulser that gives a pulse of 5 volts, pull up. That pulser is on a water meter and each round it makes 100 pulses. So if i can simulate 50 pulses the device should see 50 pulses. The flow has a max of 40 l/min. Thanks
Yes, the voltage level of the output pulse can be set in the settings screen for the output mode, from 1.0V up to 24.0V. Thanks for watching and the question.
@@three-phase562 Thanks for pointing me out. Did found it. Measuring with a scope shows it just fine. If I am correct this is only pull-up. Is it also possible to make it pull-down? I think I should use a resistor, correct?
@@AE31011 Its a switched output so if you connect the +out terminal to the pulse input and the com terminal to 0V, it should switch okay. If you have problems, then yes you could try a pull up / down resistor to see if it improves. Alternatively on the settings screen, you can change the 'way' from 'level' which would be the voltage output to 'oc' which is open collector switching and voltage free. You could then use that with the power from the sensor circuit.
Another nice video to start the sunday, thanks.
