|
When Denable and Dwrite is high , the voltage of PLLOUT is 0 V. And the Dtap is turn high with no delay when the Denable turns high.
After power up and configuration(the WSR,WCR,CR are all set to 11111111), the readout data is no change whenever the input analog signal and rofs,bias,oofs
changes. I have test useing the DAC to supply the Dspeed voltage, and change a new DRS4 chip, but all is the same. The readout data is strange : the first |

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. |

Hi,
I am trying to understand some details about the timing calibration.
We wrote our own code but we more or less use the ideas of the Oscilloscope class. |

The evaluation board normally has 1024 bins per channel. We offer an option with 2048 bins using channel cascading, to capture longer waveform windows.
The binary data format is however defined as having 1024 bins. Therefore, for the 2048 bin boards, the software averages over two adjacent cells and saves
effectively 1024 bins. The noise of each bin improves this way by sqrt(2). The time however is not very well defined, since you average the voltage of |

There is software for DRS4 board and positron lifetime measurement availiable. Still in beta but works. Its usable for measuring time between
pulses in two or three channels and histogramming that time. (May be time of flight measurement should be tested too) Project code is here: http://sourceforge.net/projects/qtpals/.
More about it is here http://iopscience.iop.org/1742-6596/505/1/012044/. |

Dear DRS4 Users,
I would like to share my expireinces with using of DRS4 Evaluation Board software (oscilloscope) after upgrade of Windows 10.
I had Windows 10 (Enterprise) in version from ~2016. It was working fine with DRS4 Scope software. Due to the company policy, Windows was upgraded |

You are the first one describing this problem (out of ~200 people), so I guess the problem must be on your side. Have you made sure to start the DRS oscilloscope
and the Command Line Interface not at the same time? Only one program can access the board at a given time. Have you tried disconnecting and re-connecting |

No, I absolutely have no idea. Both DRSOsc and drscl use exaclty the same code to access USB.

Hello,
I need to write a script in C++ to take data using the DRS4 evaluation board v4. For that, I used the drs_exam.cpp example as a reference. This
is my code (see attachement 2), which is very similar to the provided example, however the difference is that I need to trigger on CH1 OR CH2. In the next |

Hello, some updates:
4. I was able to capture correct waveforms using c++ code. I needed to use the function SetTriggerDelayNs() to properly capture
my waveforms. |

1. Transparent mode is not needed for the hardware trigger, no idea why the code is there. You can probably remove it.
2. EnableTCal is only for the sake of having some waveforms at the input. Indeed you have to disable it to sample real signals.
3. EnableTrigger() is there to enable the hardware trigger. The flag2 is ther for historical reasons (used in older versions of the board). |

I have saved some waveforms using the oscilloscope application in both binary and xml. I can see that the xml file gives me proper data values
but when I try to read the binary file using IDL, it does not seem correct. This is a screen shot of the pulse I saved: |
