Hello.
1. Recently I tried to set up pulse trigger on my Hantek 6074bc unit however it's not working at all.
I tried to trigger on built in 1kHz 2Vp-p generator setting up pulse trigger to trigger on + pulse equal to 500us - in AUTO mode waveform shows in random places, in NORMAL mode waveform doesn't show at all.
I tried to modify trigger parameters to use less than or more than condition, pulse polarity, without any difference.
I'm using Hantek-6000 ver2.2.6 software.

2. When setting ALT trigger, timebase could be set up separatelly and independently for each channel. This could be even seen on bottom status bar when sampling rate changes! I do not think such behaviour of this device was intentoned!

Additionally thire is some inconsistency in menu options in ALT trigger - I mean Pulse condition have more options if it's set up as trigger source, and have less options when it's set up as a trigger for channel in ALT trigger soure - pulse polatity is missing.

Dear Sirs

Thank You for fast response. After upgrading FPGA to F005 pulse trigger works correctly.
Additionally it's clear now how ALT triggering is working - it obviously allows to set time base separately for each channel. Below are screnshoots of:
CH1 - 500us/Div, pulse trigger +equal to 500 us
CH2 - 200us/Div, edge trigger on - slope
Both probes are connected to built in square form generator.

Hello

     I recently purchased an Hantek 6074BC and I am facing the same problem. I have noticed that my scope's FPGA is version F004.
     Unfortunately, the link for the file above with the new version has expired
     Is it possible to send me a new link wit some instructions on how to update the FPGA?

         Thanks a lot,

                       Marcelo
