COUNTING BOARD
M8784
OVER VIEW
The M8784 counting board is a PCI bus add-in board type coun-
ter. The M8784 functions as a photon counter when combined
with a photon counting head, etc.
The counter of the M8784 includes two counting circuits (double
counter method) capable of counting input signals with no dead
time. The internal memory allows pulse counting over extended
periods with a high time resolution (10
µs).
A maximum of two M8784 boards can be simultaneously control-
led from a PC, making it possible to perform simultaneous dual-
channel measurements.
Initial setting for the M8784 is simple and easy due to PnP (plug
and play). You can start measurement on the day you receive the
M8784.
The M8784 is designed to install into a PCI bus slot of desktop computers and cannot be used with notebook-sized computers. When
using a notebook computer, use the C8855 counting unit also available from Hamamatsu.
· Ideal for long-term data collection such as in biological clock monitoring *
)
This feature is feasible if the memory recording time is longer than the time needed to transfer the count data to a PC and write it
into the storage medium. This allows time-resolved measurement (minimum resolution: 10
µs) over a long period of time.
Memory recording time is calculated from "counter gate time
× memory data width".
(Example: minimum resolution 10
µs × maximum memory data width 256 000 = 2.56 s)
*
)
Standard sample software may not work at some conditions depending on the combination of measuring time and time resolution.
Please consult with our sales office in advance with information of your condition.
· Time-resolved measurement of chemiluminescence (minimum resolution 10
µs)
· Supports different kinds of measurements
The M8784 is fully controlled by DLL (dynamic link library) functions that supplied with the M8784.
User can create own software program, which is adequate for various type of user measurement, based on the DLL functions.
