For those cases we then recommend the use of USB2.0. The use of USB2.0 is always possible, but there might be limitations in the Note maximum count rates for certain detector types and/or detector operation modes.

The maximum frequency of the start pulse must not exceed 7MHz. Do not forget to save the ini file after any changes you make and restart the software. For further information check the software manual. Note SC-TDC-1000 S Series Manual | Surface Concept GmbH... -
Page 14: Tdc Start Output (Sub-R 85 And E8 Only)
The TDC holds an internal electronics, which provide the TDC start signal for further extended measurement use. The “START OUT” (BNC socket) provides either the external start if applied or the internal start, generated by the FPGA. SC-TDC-1000 S Series Manual | Surface Concept GmbH... -

Page 18: Tag Signal Input (Sub-R E8 Only)
The number of bits which are available for each detector event (x, y, t) is defined by an additional parameter called “nBytes” in the tdc_gpx3.ini file. The corresponding entry in the tdc_gpx3.ini file is: nBytes = X The default setting is X is an integer value of either 4 or 8. SC-TDC-1000 S Series Manual | Surface Concept GmbH... -

;must be set for using the state/sign input. Hereby the state/sign input functions in combination with the tag signal functioning as a timer, counting the internal 80MHz clock signal of the FPGA. A signal on “TAG IN“ resets the timer to 0. SC-TDC-1000 S Series Manual | Surface Concept GmbH... -
Page 20: Adc Input (Sub-R E8 Only)
In this case one has to use the positive input (“ADC IN +“) of the ADC, while terminating the negative input (“ADC IN -“) to ground. Please be aware that this way of operating is working, but it is more prone to noise. SC-TDC-1000 S Series Manual | Surface Concept GmbH... -
