I presume they are software bandwidth upgradable? |
| simone.pignatti:
Yes they are: Bandwidth Upgrade Option Bandwidth upgrades from 100 MHz to 200 MHz Bandwidth upgrades from 100 MHz to 350 MHz Bandwidth upgrades from 100 MHz to 500 MHz Bandwidth upgrades from 200 MHz to 350 MHz Bandwidth upgrades from 200 MHz to 500 MHz Bandwidth upgrades from 350 MHz to 500 MHz |

Interesting about the overload recovery time. Do they really mean 0.5 PERCENT the recovery time of other scopes? |

If Rigol wants to have any chance to make a name for themselves and compete then the firmware has to work 100% from day one. I just did a price comparison and the pricing on the DS7000 series is pretty much on par with similar instruments from A brands. There is very little room for justifying a make-do scope with partly working firmware in a professional environment where time equals money. I'm sure people will say I'm too negative but let's be real: Rigol doesn't have a very good track record and fixing firmware on their higher end models has taken long in the past. I'm looking forward to some in-depth tests which go deeper than twiddling some knobs to see what is what. --- End quote --- This. Some years ago, we bought Rigol's flagship: the DS6104, including most options (uart, spi, i2c decoding etc.). When we started to use the remote LAN connection, we hit the following three bugs: bug no. 1: (reported at, and confirmed by, Rigol in October 2015) When I run this software: https://www.teuniz.net/DSRemote/ and select LAN connection, I get randomly the response: "command error". This blocks the connection for 5 seconds and a timeout occurs. This happens randomly, and when it happens, it does after sending different commands. So, it's not related to one and the same command. Sometimes the program runs fine for minutes. bug no. 2: (reported at, and confirmed by, Rigol in Januari 2017) Apply a squarewave of 1KHz to channel 1. Set triggering to normal, rising edge. Set the memory depth to 1.4Mpts. Acquire the signal, then set the scope to STOP mode. Download the waveform in RAW mode, format BYTE. When you observe the downloaded waveform, the triggerpoint is shifted about 460 nanoSec. bug no. 3: (reported at, and confirmed by, Rigol in December 2016) When setting the treshold for the UART serial decoding, it seems to work fine. But when asking for the threshold setting, the value is always 10% of the actual value. This bug happens when the probe attenuation is set to 10:1. These bugs are still unresolved and make it impossible for us to use the remote connection. We have learned our lesson and we will never buy Rigol stuff anymore for our business. |

I think there are quite a few things interresting about this scope. It finally has some functions now performed in hardware instead of in software unlike all the other scopes from Rigol. Decoding beeing probably the most useful out of them. The decode function in all rigol oscilloscopes at least up to the 4000 (i am not sure about ds6000) series is in my opinion barely usable. It just slows down too much and has a lot of actual glitches in the data because the software has problems to correctly decode the on screen waveform data. Hopefully the implementation in hardware is executed good enought, under this circumstance this would be a pretty big selling point for most people i think. Also if i understood their marketing correctly math functions are also now completly in hardware. This would negate the huge loss of responsiveness from the ui while using math. Beeing able to display 4 fuctions at the same time is also nice to have. But there is one big downside to this: I could not find anything related to custom math functions in the datasheet nore could i see it in their marketing videos showing off the math functions. So I assume it is not implemented in this model or it is missing in the documentation and i overlooked something in the video. Would be something interesting to look up if anyone here gets their hands on this. This function was quite useful from time to time, so it would be a bit dissapointing if it really was missing. Also a quote from the store of one of Rigols distributors Batronix for the memory upgrade for the DS7000 series: "[...] Simple activation via software code (memory is already build-in). Please specify the serial number of your oscilloscope, [...]." So its safe to assume that all options are again activated with codes generated from the serial number if the description on the distributors store is correct. If this scope is both option and bandwidth hackable then 2200€ without tax is really a unbeatable price for a 4 channel 500mhz scope with such high amount of sample memory and really high update rate + hardware decode. But I wonder how responsive the touchscreen and the overall UI will be. |
