Page 6: General Safety Precautions
General Safety Precautions Use Proper Power Source The SIB164B-1018 is powered with a +5V power source directly from Vertilon’s PhotoniQ multi-channel data acquisition systems. Use with any other power source may result in damage to the product. Operate Inputs within Specified Range To avoid electric shock, fire hazard, or damage to the product, do not apply a voltage to any input outside of its specified range. -
Page 7: Product Overview
66 socket pins that connect the PMT’s 64 anode signals, last dynode output, and high voltage input to the board. The high voltage bias to the PMT is supplied through the SIB164B-1018 on a specialized cable from the PhotoniQ. The anode signals are routed to an on-board resistive anger logic circuit that generates four anger signal outputs. -

Page 11: Typical Setup
SIB164B-1018 and PhotoniQ provide a discriminator threshold adjustment signal to the SIB164B-1018 and a trigger to the PhotoniQ from one of the SIB164B-1018’s two discriminators. A high voltage bias of up to negative 1000 volts is sent through the SIB164B-1018 to the PMT from an SHV connector located on the rear of the PhotoniQ. Note that the rear panel high voltage output is an optional configuration on the IQSP418 and IQSP518. -
Page 12: Photomultiplier Tube Anode Circuit
Photomultiplier Tube Anode Circuit The 64 anode signals (P1 – P64) from the H7546B / H12428 MAPMT are routed directly on the SIB164B-1018 to the resistive anger logic circuit shown in the figure below. The four outputs labeled V1 to V4 are available on SMB connectors on the edge of the printed circuit board. -
Page 13: Last Dynode Output Preamplifier
Referring to Figure 5, negative going pulses from the preamplifier are compared to a threshold that is adjusted using either the trimmer pot on the SIB164B-1018 or an external DC voltage source. The adjustment method is selected with jumper JP4. When the trimmer pot is selected, the leading edge discriminator threshold is determined by the on-board potentiometer VR1 (LEAD). -
Page 14: Zero Slope Discriminator
SIB164B-1018 Sensor Interface Board for Hamamatsu H7546B / H12428 MAPMT Zero Slope Discriminator The zero slope discriminator (ZSD) works by generating a trigger signal at the inflection point of the input pulse. It is at this point where the pulse is at its peak and its slope transitions from positive to negative. Since AMP4 effectively operates on the derivative of the input pulse, its output crosses zero where the slope of the pulse is zero. -
