2) The way the scope handles intensity grading at time bases <= 50ns/div when two channels are enabled with Normal Sweep is not the same as all other modes - it feels incongruous and incorrect.
[FW v.01.01.00.02 / FW v.02.01.00.03 /
FW v.03.00.01.03]
14) When the RS-232 baud rate is set to AUTO 57600, it is incorrect. When set to USER 57600, it operates correctly.[FW v.01.01.00.02]
15) Bus decoding does not decode the full ASCII set. Missing characters:[ . , : ; - _ ! $ % & / ( ) = ? ] - everything between square brackets (except spaces). [FW v.01.01.00.02]
16) ANTI-ALIASING does not prevent waveform aliasing to any degree, although it can remove some
image aliasing (e.g. moire patterns) under certain conditions.
[FW v.01.01.00.02 / FW v.02.01.00.03 /
FW v.03.00.01.03]
17) There is a visible offset from center position when using AC-coupled Triggers (including filtered LF and HF) at lower time bases (<= 2us/div), as well as serious jitter with certain settings.
[FW v.01.01.00.02 / FW v.02.01.00.03 /
FW v.03.00.01.03]
18) There is a bug when using DOTS mode with AUTO/14M/56M memory depths @ >= 5us/div. It affects the waveform update rate (much reduced) - and can also affect the visible display of the waveform.
[FW v.01.01.00.02 / FW v.02.01.00.03 /
FW v.03.00.01.03]
19) When in HighRes mode and reading display memory from the DSO with SCPI, if the time base is <= 20us, the DSO returns 1398 bytes instead of 1400.
[FW v.01.01.00.02 / FW v.02.01.00.03 /
FW v.03.00.01.03]
20) When reading display memory with SCPI while the DSO is STOPped and zooming out, the DSO returns (correctly) a decreasing number of display memory bytes until < 6, and then it incorrectly starts sending 1400 bytes every time (a nonsense waveform) instead of 2 (a single line).
[FW v.02.01.00.03 /
FW v.03.00.01.03]
21) Log() function in MATH -> Advanced -> Expression doesn't work.[FW v.02.01.00.03]
22) All SCPI commands related to CAN triggering appear to be missing in the latest FW.
[FW v.02.01.00.03 /

=====================================
To get the full firmware version info from the DSO, follow these instructions:Go to the Trigger menu and set Edge trigger.
While keeping the Trigger menu open, you are going to use the 6th and 7th right-side menu buttons as follows:
Press the [Menu7][Menu6][Menu7][Utility] buttons one after another
quickly.
Then check additional info under System -> System Info.
You should see something like:
Software version: 00.01.01.00.02
Hardware version: 1.0.1.0
FPGA version:
SPU 03.01.02
WPU 00.06.00
CCU 12.29.00
MCU 00.05
If you DON'T see this detailed info = start again, and press those 4 buttons
faster.
To escape from this mode, press again [Menu7][Menu6][Menu7][Utility] while inside Trigger menu
- or reboot the scope.

For those planning to upgrade/downgrade firmware:Do the upgrade ONLY during bootup - not from the GUI/Menus/OS asking for file/etc. or you might lock up the scope - losing any trial options you have remaining - and requiring you to do the upgrade again anyway using the method listed below:
You do this by using two hands when booting up - one thumb on the 'Power On' switch - one thumb on the 'Help' button. When you
press 'Power On', all of the scope
LEDs will light for ONE SECOND - during that brief period, you must
PRESS AND LET GO of the 'Help' button. It can be a little tricky, but if it works, bootup will stop before the Rigol logo with the 'SINGLE' button lit (if it doesn't, turn off power and try again until you get it). Then insert the USB stick with the file on it. The CH1 LED will flash as the DSO loads the file.
Once updating is finished, several of the LEDs will light up - and all flashing, etc. will stop. That means it's finished, so you can remove the USB stick and reboot - but please take notice of the following:
Note: Rigol has changed the the structure of unit settings stored in FRAM, so if you have upgraded/downgraded between the major versions of v.01 & v.02 (i.e. v.01.XX.XX.XX to v.02.XX.XX.XX - or vice-versa), it's a good idea to hold in the left-menu F6 button (sixth gray button down on left side of LCD) during the first reboot after loading (to clear FRAM) - otherwise the DSO can hang when switching between various menu items.Finally, check your firmware version using the method listed above.
