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.
Electrostatic Discharge Sensitive
Electrostatic discharges may result in damage to the SIB164B-1018. For this reason, the SIB164B-1018 board is
intended to be operated in a user’s conductive instrument enclosure.
Do Not Operate in Wet or Damp Conditions
To avoid electric shock or damage to the product, do not operate in wet or damp conditions.
Do Not Operate in Explosive Atmosphere
To avoid injury or fire hazard, do not operate in an explosive atmosphere.

Product Overview
The SIB164B-1018 multianode photomultiplier tube interface board provides the mechanical and electrical connectivity
between the Hamamatsu H7546B / H12428 64 anode PMT and external signal processing electronics such as Vertilon’s
PhotoniQ multichannel data acquisition systems. The MAPMT is mounted to the bottom side of the SIB164B-1018
through 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. These
outputs connect using four coaxial cables to Vertilon’s PhotoniQ IQSP418 or IQSP518 multichannel data acquisition
system where the charge from each is separately integrated, digitized, and sent to a PC for display or further signal
processing. For applications utilizing the last dynode output of the PMT, the SIB164B-1018 includes a two stage high
speed preamplifier whose output is available on an SMB connector. One of two on-board discriminators can be used with
the last dynode signal to generate a trigger to the data acquisition system or other external electronics. The outputs from
a leading edge and zero slope discriminator — which respectively generate trigger signals based on threshold and pulse
peak — are available on SMB connectors. Several user adjustments are included for optimizing system gain and trigger
thresholds for the discriminators.
The various functions on the SIB164B-1018 are described in greater detail on the following pages. When necessary, refer
to the functional block diagram shown in Figure 1 below.
