Multiparameter Multichannel Analyzers / Questions and Answers
- What are the typical measurements or applications that MPA4 or MPA4T can do? I tried to understand MPA4 on FAST ComTec's website but the information there is not very accessible to non-experts like me. We are thinking about buying a MCS6 or MPA4T.
- I have a customer trialling the MCA4-1 and he has asked if we can do repeat counts that store the result after each count.
- I have a question about the RTC timestamps on the MPA-3. I understand that the RTC units are 50 ns, but in our list data we only see RTC values that end in even numbers printed, indicating that our actual time resolution is 100 ns. Is this normal?
- Is the MCA4 or the MCA4-2 an alternative to the functionality of the MPA-3/2P 2 parameter MPA-3 system? This is for acquisition and display of analog (0-5V) X and Y position data from a position-sensitive detector.
- In the MCA4 it is included a dual fast MCS option. Only two channels? Is it possible to add one more option for the other two channels? Do I need to purchase one TAG bit option for each channel? Is the Replay Software included also in the MCA4-MP2 System?
- What is the MCA4-MPASW2 / 4 software? If it is the multi parameter software for the MCA4-MP2 / 4, it should be supplied with them. Instead, I see the standard MPANT in the description. The configuration of those new systems are not completely clear to me
- Please advise for following MPA-NT/MPA-3 software question. What are the relation between dead time, live time, true time, real time, Run time under the MPA-NT software?
- I would like to use the dig4 channel to control the MCS6A. I'm trying to understand if and how it is possible to select this option directly from the DLL functions and not using the MPANT software.
- What about Windows 8?
- What advantages would the MPA4 provide, relative to the MPA-3?
- Is it possible with the MPA-3 to get time spectra individually say for ADC1 (T1) and ADC2 (T2) ? Is it possible to get a time spectra for the difference (TI - T2)? Is there any common reference of time for all ADC inputs?
- It doesn't work with Combined conditions on 2 different ADC (ROI1 of ADC1A "OR" ROI1 of ADC2A), Why ?
- I would like to use the MPA-3 for building a spectra containing the sum of the counts from several smaller detectors to get a "superdetector". Is that possible?
- She is not getting time spectra using RTC option. The AUX input was not used. Is it not possible to get time spectra with RTC option without using AUX input? She opted for software start but no spectra came.
- It's possible to control the MPA server by sending commands over a TCP/IP net ? - what are the messages to send : can we do all the functions available in the DLL?
- Is it possible to inspect MPA-3 datafiles under Linux (offline, without connected hardware) (MPANT seems not to run under wine)?
- When using the logsums command we noticed that the logfile does not update until we exit out of the program or the logfile name is changed. Is there any way to get the sums to automatically be saved into a .txt file after we have replayed the data?
- Is it possible to read "on line" all the events with an external application written in VB.NET or Labview or C++ ... ?
- Is it possible to do time-of-flight measurements using MPA-3 with RTC by acquiring an ADC spectra for a time window and starting the time by a chopper signal?
- I use fast position-dependent detectors with delay-line read out. The maximum count rate that I can reach using two 7072T TDC's in coincidence and MPA-3 is only about 350 kHz per input. Is there a solution that can handle a higher count rate?
- On what conditions in the ADC/ MPA-3 can result in counts (especially large numbers of counts) appearing in MPA-3 channel 0. The customer is experiencing this. How can he eliminate it?
- About the 4K and 16K FIFO: Can you give me some firm ideas on how to recommend to customers which they need?
