  • Page 2 1. The FCA3000/FCA3100 Measuring and Output Data Transfer Modes Let’s begin with a summary of the different measurement and output data transfer modes in the FCA3000 and FCA3100 series products. The FCA3000 and FCA3100 Series products can operate in several different measuring and data transfer modes: ...
  • Page 3 The dead-time between measurements in this “real-time” transfer mode is <250 microseconds. To reach this throughput rate, the communication process is simplified:  Controller talker /FCA3000 listener: “go to Talker only mode and start measurement”  FCA3000 talker/ Controller listener: “sending result data”  FCA3000 talker/ Controller listener: “sending result data”  Etc… www.tektronix.com/frequencycounter...
  • Page 4 In the FCA3000, true zero-dead-time measurements can only be made up to 750K Samples (internal memory limit), after that there must be a gap in the data. Zero Dead-time Data Measure Gap in the data Gap in the data Process Transfer www.tektronix.com/frequencycounter...
  • Page 5 Tp1(i) is the timestamp of the first positive trigger event Tp2(i) is the timestamp of the second positive trigger event Tn1(i) is the timestamp of the first negative trigger event Tn2(i) is the timestamp of the second negative trigger event www.tektronix.com/frequencycounter...
  • Page 6 (segments where data is being fetched from and segments where new data is written to). The roles of the segments can be switched around as needed. www.tektronix.com/frequencycounter...
  • Page 7 Error -224,"Illegal parameter value" error is generated if you try to fetch a larger number of samples than remains to fetch in the buffer. This includes also the case of using the "MAX" parameter when already at the end of the buffer, and you have already fetched all samples. www.tektronix.com/frequencycounter...

  • Page 8: Format:smax

    To switch off Talker Only mode, you use the ESC key (C) on the front panel alternatively send an Interface Clear (IFC) over GPIB. Further settings to implement for successful high-speed talker only transfer are: DISPlay:ENABle OFF. FORMat REAL or FORMat PACKed. ARM:COUNt 1 TRIGger:COUNt 1 INIT:CONT ON. www.tektronix.com/frequencycounter...
  • Page 9 Frequency (smart calculation) Time Interval (smart calculation) Time-stamping Voltage Totalize This means that Frequency BtB and Period BtB is OK, but not “smart” frequency where a regression line fitting between several time-stamped data is used to improve the basic resolution. www.tektronix.com/frequencycounter...
