Hi.
I asked about using multi boards some days ago, and I got answer to use external trigger. (Thanks Stefan!)
And here is another question. I made two external triggers and try to acquire coincidence data using two boards. but DRS Oscilloscope program can connect only one board and don`t acquire both of them simultaneously.
So I tried to use two computer for each board separately, but, well, you already know, I failed to acquire because two computers don`t promise to synchronize the two boards acquisition.
Is there any method to solve this problem?
1. I want to acquire coincidence data from the two DRS 4 Evaluation board V4 simultaneosly.
2. I have external trigger to provide the two boards at the same time.
3. How can I get data from the two boards?
Best regards.

You have to write your own program. DRS Oscilloscope does not (yet) support this. Take drs_exam.cpp as a starting point and try to extend it to two boards. One tricky point is that the external trigger may only fire AFTER the two boards have been read out. So you need some means of re-enabling the external trigger after you read out both boards.

That`s very bad news for me. I don`t have much time to study & write C programming...
Anyway, Thank you very much Stefan.
Best regards.

Stefan Ritt | DRS Oscilloscope for Raspberry Pi and Mac OSX 10.8 | I made a pre-compiled package for Mac OSX 10.8 (Mountain Lion), so one should be able to install the DRS Oscilloscope software with one mouse click on a recent Mac.
The Makefile in the tar ball now also supports OSX 10.8, so one could even compile it from the sources on a Mac, after libusb-1.0 and wxWidgets have been installed. That might then also work on older versions of OSX.
In addition, the software has been adaptes so that it compiles nicely on a Raspberry Pi (http://www.raspberrypi.org), a screenshot has been attached. Together with a Raspberry Pi and an old screen, the evaluation board is one of the cheapest available oscilloscopes.

Hi.
I have 2 DRS4 evaluation V4 boards, and I want to use these 2 board to multi board DAQ system for 4 ch vs 4 ch DAQ.
But there is no option for multi board use. I just only find the multi board trigger mode check button on DRS4 Oscilloscope program, but I couldn`t check.
Is there any method to use multi board?
Best regards.
Gyuhee.

This mode is not yet implemented in firmware. Maybe I find some time towards the end of this year to add this. At the moment, you have to build and external trigger to synchronize the two boards. There are also 16-channel boards on the market where you would not need a multi-board mode. Just Google for "DT5742".

Thanks Stefan.
I will build external trigger system. |

I have some question according to GetWave function. In drs_exam.cpp simple GetWave(0,0,wave_array[]) etc...is used. Is there primary (cell) calibration, secondary calibration (Readout) and remove Spikes used, as in DRS Oscilloscope application?

Yes, yes, no. To get spike removals, you need the function RemoveSpikes from Osci.cpp in the DRSOsc project. |

The "and" in the trigger section means now "coincidence". So the V4 board can trigger on a coincidence between two or more channels. If there is no pulse at the same time on the coincidence channels, the board will of course not trigger. The according firmware was introduced in V4, so please look at drs4_eval4_app.vhd (not eval3).
I just realized that the V4 firmware might be missing in the distribution, so I have attached it here. Look for drs_ctl_trigger_config.
Best regards,
Stefan

Ah, great, that helps, Thank you!

Hi,
Our group had previously heard that a "DRS-5.0" might be on the horizon and that it may have ethernet capabilities as well as 16-input channels (we heard this when ordering the DRS-4). Is this still in the works and accurate information? If so, is there a rough estimate to the "release date?"
Thanks for your time,
Zach Miller

You mix up two things: The DRS5 chip is a new device with improved samling speed (10 GSPS) and lower dead time. This chip might come in 2-3 years. The 16-input board you mentioned is a DAQ board based on the DRS4 chip. This board well be operational beginning of 2013 as a prototype. It is not clear however at this point in which way this board will be made available for public. Maybe we will license this to industry. The design is however pretty much defined: 16 channels with gain 0.1-100, 1 GHz Bandwidth, Gigabit Ethernet output, and multi-board capabilities. Trigger on each channel with logical combinations. 80 MSPS continuous sampling (in addition to the DRS4 sampling). Each channel can be biased 0-210 V for SiPMT or APD power. A 19" 3 HE crate will host 16 boards with 256 channels.
