GeneralTechnical Specifications

The Driver/Preamplifier electronics DZA-S3901-4
serves as an adaptation subassembly matching theHamamatsu MOS Linear Image Sensors series S3901- S3904 to the frontend electronics unit of a tec5 operating electronics.

Diode arrays:

In most applications, the photodiode array is plugged
into the DIL-22 socket mounted to the soldering side of
the printed circuit board.
The interface for the Frontend electronics complies totec5 specification ‚Sensor-1A‘ (MICS-10 connector andan SMB flange socket with pin contact, video signal‚single ended‘) and is therefore compatible to the interface of MMS Spectral Sensors defined by Carl Zeiss.

DZA-S3901-4 forCarl Zeiss MCS Spectral Sensors
For use with MCS spectral sensors from Carl Zeiss,the electronics can be plugged directly onto the photodiode array integrated in the spectrometer and is fastened to the spectrometer housing by means ofscrews. Based on the MMS compatible sensor interface, the Driver / Preamplifier electronics allows to run
MCS modules with all operating electronics units which
are compatible to the MMS Series.

Features
The electronics module converts the video current
pulses originating from the diode array to voltage
pulses. As input signal source, the 'active video' or the'active minus dummy video' may be selected via solder
gap BR2. The 'active minus dummy video' signal is thedefault factory setting.
The digital clock signals for controlling the array areconverted from TTL or CMOS (HC) level to the levels
required by the photodiode array.The module is factory
preset for a diode array type S3904. For different typesof arrays, components R4, R12, C7 and C13 have tobe replaced (see below)!

Digital control inputs:
START:
Initiates a read-out cycle at HIGH
level of the signal START, triggeredby a falling edge of the signal 'PHI2'
PHI2:

Array master clock. If a read-outcycle has been initiated, one diode isread out at each rising edge of PHI2
until the end of the array is reached.

Digital control output:/EOS:
EndOfScan, the signal /EOS is HIGH
during the read-out cycle. After reading out the last photodiode /EOS is
LOW for one HIGH period of the signal PHI2 to indicate the end of thearray.
