DS2000A Upgrade Utility
Willi100:
Hello,
I did the full upgrade and it worked fine. (Software before: 00.02.00 - after: 00.02.01)
But I lost the accurate voltage measurement.
Before upgrade I checked the RMS voltage precision at different frequencies.
Example:
Test Signal: 1 MHz Sinus with 0dBm = 224mV RMS
Measured with: Boonton RF- Millivoltmeter 92E = 224mV RMS
Measured with: DS2072A before upgrade = 224mV RMS (@500ns)
Measured with: DS2072A after upgrade = 227mV RMS (@500ns)
Than I let run a Self Calibration. After that I measured : 233mV RMS
The calibration did not help. The calibration makes it worse. :(
Test gear:
Signal Generator IFR2023B
TRUE RMS RF Level Meter RACAL DANA 9303
BOONTON RF Millivoltmeter 92E

Hello,
here the Frequency Response: DS2072A (Hardware version:2.0) 70MHz and upgrade to 300 MHz.
(Measured with 50 Ohm termination)
I measured RMS level at 18 frequency points with my True RMS Level Meter and with the Oscilloscope by hand.
For calculation and graphic I used Excel.

To answer your questions:
Yes there are trials enabled - I will take a shot and send it if you need that. Just let me know.
1. Yes I have done that. Only the "single" light is lit.
2. Just like adi101 said, as soon as you insert a USB (containing only the DS2000Update.GEL) the CH1 lights for just a moment (not what I'd call flashing) and then ALL of the other lights are lit solid.
3. I have tried re-inserting the USB stick and I have tried numerous different keys. No change in the symptoms. I have also left the key inserted for a "long time" (5-10mins). Again no change. I have retried the sequence 10+ times. No change.
I have tried 7 different keys now from really old 1GB devices, several 4GB and a couple modern 8GB devices. I have tested all of these USB keys using the file browser in the "storage" menu with the scope booted normally and all of the USB's seem to work fine, but I have not been able to install the older firmware's from any of them using the "help" bootloader technique.
I am keen to try out anything that you might need to get to the bottom of this.
Thanks.

Sorry if this has been answered, but I too am having the exact same issue with all the lights lighting up and no reaction afterwards when I plug in the USB stick. I am using 00.03.00.SP1 (factory installed). Is there any solution to this problem yet?
airs:
Just tried this utility and it worked perfectly the first time. One thing to note is you need to be patient when CH1 is flashing - the FW update took quite a while for me (5 minutes?)
Btw, my unit came with Software: 00.03.00.SP1 and Hardware: 2.0
I used a 8GB USB 2.0 Kingston Data Traveler stick, formatted as FAT32 with Default Allocation Size. It had nothing on it other than the .GEL file.
Thank you so much for this!!
Gandalf_Sr:
I need the I2C/SPI protocol analysis function. I was considering buying a DS2072A and doing this upgrade but I can see a lot of hits on the Internet saying there are decode bugs with SPI/I2C/UART on Rigol scopes.
Can anyone confirm or deny the existence of this problem or point me to more info?
