P-9802 Optometer
P-9802Z01 Amplifier Module

The P-9802 is designed as a 2 to 36 channel optometer for use under remote control operation. Typical applications are burn-in and life time measurements but also light distribution measurement applications. Its metal housing offers excellent shielding even in strong EMV ambient conditions. Its electronics design is based on a master board with an external RS232 interface and an internal I2C bus. Up to 18 amplifier modules can be controlled by this internal bus through the master board. The number of modules is order specific allowing the meter to be configured to individual needs. The basic version of the P-9802 has one amplifier module with two signal inputs. Additional amplifier modules allow the optometer to be expanded up to a maximum of 18 amplifier modules, i.e. 36 signal inputs. Each module implements a signal amplifier with two switchable signal inputs. A microprocessor controls the operating modes, the input channel switching and the calibration data. The calibration data of each module is stored in eeprom. The detector heads are connected via BNC sockets located on the front and back panels of the instrument. The P-9802 offers a highly linear 12 bit ADC input with 7 manually or automatically selected gain ranges. The max. error within this wide dynamic range is 0.2 %. The flexibility to combine the P-9802 with most Gigahertz-Optik detector heads enables it’s use in a wide application range of radiometric and photometric measurements. The instrument is DC voltage operated with external AC power supply.
