Description of Operation
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 the
default factory setting.
The digital clock signals for controlling the array are
converted 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.

Preamplifier electronics for
Hamamatsu N-MOS Linear Image Sensors
types S3901 to S3904
Sensor chip socket for direct insertion on PCB
Device input: sensor chip
Device output:
tec5 15 bit Front End Electronics (FEE-HS) or
tec5 Electronic Sensor Multiplexer (MUX-4P /
MUX-8A) with sensor interface ‚Sensor_1A’
PCB dimensions 74 mm x 40 mm

General
The preamplifier electronics DZA-S3901-4 serves as an
interfacing component between the Hamamatsu NMOS Linear Image Sensors of series S3901 to S3904
and the Front End Electronics board of a tec5 operating
electronics. In most applications, the photodiode array
is plugged directly into the DIL-22 socket mounted to
the soldering side of the PCB.
The interface for the Front End Electronics complies to
tec5 specification ‚Sensor_1A‘ (MICS-10 connector and
a 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 for
Carl 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 of screws. Based
on the MMS compatible sensor interface, the preamplifier electronics allows to run MCS modules with all operating electronics units which are compatible to the
MMS series.

For different types of arrays, components R4, R12, C7
and C13 have to be replaced (see below)!

Digital control inputs (TTL/HC level):
START:
Initiates a read-out cycle at HIGH level
of the signal START, triggered by a falling edge of the signal 'PHI2'.
PHI2:

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

Digital control output (TTL/HC level):
/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 the array.
