First time poster. Read through the entire thread tonight, verified both issues (5us jitter, ac trigger coupling). Testing new firmware. Verified it fixed these issues.
Test setup:
Scope: DS1054Z (unlocked all options)
Probe: As delivered Rigol probe, 1X configuration, compensated via test signal square wave
Reference Clock for Test: 20MHz can oscillator on breadboard. Driven at 3.3V.
Original configuration, DC coupled input, DC coupled trigger, no trigger offset:
Original configuration, DC coupled input, DC coupled trigger, 5us trigger offset:
Original configuration, DC coupled input,AC coupled trigger (0V), 0us trigger offset:
** AFTER BETA FIRMWARE UPDATE **S/W 00.04.02.SP3, DC coupled input, DC coupled trigger, no trigger offset:
S/W 00.04.02.SP3, DC coupled input, DC coupled trigger, 5us trigger offset:
S/W 00.04.02.SP3, DC coupled input,AC coupled trigger (0V), 0us trigger offset:
Sorry the V/div and us/div are not consistent. I was excited to see everything working and didn't keep notes between screen grabs!
After the firmware update, all of my options remain unlocked, for those who suffered through entering all of those keys!
**UPDATE THIS AM**
None of the buttons work if I power up the oscilloscope without the USB stick used to flash the scope installed. If I power cycle with the USB stick in, I hear a "beep" on power up (normally quiet as I have sound disabled). Then the message box appears to update firmware with the same version on the USB stick. I select cancel, and everything works fine after that. Very odd. I can also confirm that the software version shown in the System panel is not updating after the flash.
