Non-S2000 Spectrometer Strobe Rate Adjustments
The table below shows the Continuous Strobe frequency (multiple strobe operation) for each type of
OOI spectrometer.
Spectrometer Strobe Rate Adjustment
USB2000 Fixed at 122Hz 1
All other OOI Spectrometers Software-controlled 220Hz-1Hz 2
1 Fixed frequency when the USB2000 is programmed with the PX2 firmware
2 The maximum frequency of the PX2; the spectrometer can actually run faster
Single Mode
In Single mode, a single lamp flash occurs during each integration period. You can modify the flash
rate by changing the integration period. Since the PX-2 has a maximum repetition rate of 220 Hz, the
minimum integration time allowed in Single mode is 5 milliseconds.
