PE60
Spectrometer Electronics
The PE60 electronics is a versatile powerful 32 bit RISC processor board based
operation electronics for spectrometers. It is especially suited for process control
applications.
It can control most of the popular spectroscopy image sensors with JETI‘s wide range of
available signal conditioning boards.
PE60 is stackable with additional boards to provide additional communication interfaces
like Ethernet & RS485 and encoders or TEC control electronics for precise temperature
regulation of image sensors equipped with peltier element.
The PE60 spectrometer electronics has the following advanced features:
6 80 MHz MIPS 4K core based RISC CPU
with 512 kB Flash Program Memory and
128 kB RAM
6 In field programmable by integrated
bootloader
6 Firmware can be utilizes for
general or user specific OEM
applications in spectroscopy
6 SCPI compliant control
syntax for setting operation
parameters, configuration,
measurement, data format,
endianes, etc.
6 Standardized JETI- Port allows to control
the JETI signal conditioning units for
CMOS, NMOS, CCD, BTCCD and
InGaAs image sensors
6 Communication interface TTL Level UART
6 16 bit 5 MS/s 2 channels ADC with
programmable offset correction and gain, 6 Communication interface SPI Master or
Slave with up to 20 Mbit/s
capable for sample/ hold and correlated
6 3 analog inputs for additional sensors
double sampling
6 DC/DC converter on board to generate
(e.g. spectrometer or ambient
temperature)
additional voltages for image specific
sensor needs from supply voltage
6 Communication interface USB High speed
up to 40 MB/s, optional USB Full speed
with up to 3 Mbit/s
