New Rigol DC Load DL3000 Series

[ornea]

The solution turns out to be :MEAS:DISCT if any one else is having issues with :MEASure:DISChargingTime?

Now if I could just get *RST to work.

Thing also locks up regularly.  Not the most stable piece of test equipment.

[bitseeker]

With SCPI commands, the capitalized letters in a command keyword indicate the abbreviated form of the command (i.e., by omitting the lowercase ones). Hence, MEASure:DISChargingTime is the same as  MEAS:DISCT. The capitalization is only for documentation purposes. Sending MEAS:DISCT is the same as Meas:discT or meas:disct (if it's implemented correctly, of course).

Having a required (capitalized) letter in the middle of a command keyword is rather odd and I would consider it very poor form (if not down right incorrect). It's not surprising that it causes confusion. It's as if someone at Rigol got a bit confused between the SCPI naming convention for command keywords and that of variables in a programming language such as C++, Java, etcetera, when coming up with their command set.

Does the new firmware v00.01.04.00.05 fix the problems described above at least partially? Has anyone tested?

Where can this new version be found? I haven't been able to locate it anywhere.

Does anyone know about the existence of "software" for hack options in Dummy Load DLxxxx?

[maukka]

The hack for the DP series PSUs should work for the loads as well.

Rigol DL3021 fully unlocked to DL3021A with color screen
Also DP832 fully hacked to DP832A with color screen



format usb drive to FAT
extract the keyfile.zip to usb drive and run SCPI command

Interesting,
I tried this on my DL3021 and it worked as aspected. Thanks to all of u that made this possible.

But is there anyone how knows how to calibrate the DL3000. I fond the calibration procedure for the DP832 her on EEVblog so I'm hoping that someone has the information for the DL3000.

[Svuppe]

I also tried this on my DL3021, and I failed over and over again.
After much swearing, I tried to reformat my flashdrive with a sector size of 64KB (default was 16KB). And then it worked.

[BLF Lexel]

I also used another program to do the hack
I have not tested it but with proper USB drivers you can do it without LAN

I used the Rigol Bildschirmkopie Tool to do so, but CMD works as well with telnet
http://peter.dreisiebner.at/rigol-bildschirmkopie/index.htm

I tried Bildschirmkopie only via Network, maybe someone makes it work with USB, but this needs correct IVI drivers to send commands

Step 1
Activate Telnet in your windows features and restart PC


Step 2
connect the function generator to the network
check if connection is good with ping
also a firewall may cause problems even with ping working, the DG1022Z I could only get sent SCPI commands on a very old standalone PC in my basement shop


step 3
get a FAT formatted USB stick and write the keyfile.bin in the main directory
https://www.eevblog.com/forum/testgear/need-help-hacking-dp832-for-multicolour-option/?action=dlattach;attach=696567

Step 4 with Bildschirmkopie

- start it
- ctrl+E to do a search on the network and connect the Rigol device

- search for devices and choose the one you want to unlock

- open SCPI commands

- check device signature

- send SCPI command with new Model name

- reboot device and check again device signature

Can hack the DC Load DL3021 to DL3031A?  Like the DG811 to DG992?

Does anyone know if Rigol added the possibility of pulling energy from the battery app other than in CC mode for the DL3031A?

[MrFox]

They didn't in the latest firmware.

I wouldn't expect it. They do solve the bugs over time, but rarely add features.

[MrFox]

Is there a way to do a manual calibration like the DP800 ?
I haven't found anything in the menu or the manual.

[maxspb69]

Use info from this file:
https://www.eevblog.com/forum/testgear/lists-of-rigol-scpi-commands/?action=dlattach;attach=754317
Try calibrate it by SCPI commands.

Just for the record:

Rigol DL3000 option licenses are different from all previous Rigol equipments. They don't use ECC and use only a cascade of CRC-16s.

When you change the models to the "-A" versions, all the 7 options get officially activated and no license is needed.

Will release new firmware and two new license "DL3-RIPPLE" and "DL3-REST" ?

[tv84]

Will release new firmware and two new license "DL3-RIPPLE" and "DL3-REST" ?

The current FW already contains these Options:

DL3-LAN             LAN Interface
DL3-DIGITAL-IO      Digital I/O Interface
DL3-HIRES           High Readback Resolution
DL3-RIPPLE          Ripple
DL3-REST            Transient Recovery Time
DL3-SlewRate        High Slew Rate
DL3-Freq            High Frequency

Definitions visible inside the FW:
Ripple: This function is an option. It is measured over a specified bandwidth, with all influence and control quantities maintained constant.
Transient Recovery Time: This function is an option. It refers to the time required for the output voltage of a power supply to return to within a level approximating the normal dc output following a sudden change in load current.

Has anyone flashed the new firmware (1.04 / 1.05) and then tried the battery discharge app? The new firmware broke that feature for me, load wont go above 0.1A regardless of settings. I found 1.02 firmware hosted online and rolled it back, and suddenly it works fine again.

Curious to see if anyone can replicate that or if it's just mine.

Issue of load current in battery app mode exists, see rigol-dl3021a-current-failing-to-load-consistently-in-battery-mode Temporary solution is to press ON/OFF few times (as the bug is random) or adjust set current afterwards slightly.

[electr_peter]

Other bugs & UI annoyances with Rigol DL3000:

• bug - pressing "SHORT" button while load is ON seems to momentarily produce lower (!!!) load current. Load current should only increase if "SHORT" is pressed
• UI bug - pressing almost any button on front panel turns a load off for no reason. It should not be so. Just a few examples:
• press CC button in CC mode, load turns off. Should not do that, illogical
• press any other mode button in CC mode, load turns off. Illogical behavior. It should work like this: press different mode button once - create a prompt "Do you want to exit current CC mode?", press different mode button second time - turn off load & go to different mode
• graph mode - many UI quirks which makes it annoying to use and severely limits functionality. Mainly because graph resets (becomes empty) during any change and doesn't remember any setting or data. This can be improved without changing core functions.

Is there Rigol support on EEVblog forum? Where to report such issues to Rigol?

Hello,

I have a question regarding the reverse protection. If on the sense lead occurs a polarity error, the load shows an error. I I don't use the sense leads, and connect a laboratory power supply with wrong polarity to the load inputs, there is a high current flowing. Is this a correct or what should be happen in that case?

Manual:

Reverse Voltage Protection (LRV/RRV)
When the polarity of input terminals (except the Sense terminals) and that of the output terminals of the DUT are in wrong connection, the load's input will be automatically turned off and the load will stop sinking the current. At this time, the beeper sounds, and a prompt message is displayed, "Reverse connection!" You can press OK to exit the prompt message. Note: If the reverse current exceeds the rated current,

Sorry for nagging again. What do you need electronic loads for? I never understood that. If I'm a power supply manufacturer, okay.
