Electronics; Pre-Amplifiers; Analog-To-Digital Converters - BIO RAD ZE5 User Manual

Changing the voltage delivered to a PMT changes the PMT's signal amplification. Therefore, assays
requiring a wide range of sensitivity can be carried out on the same instrument. The PMT voltages
optimized for a specific application are stored in the software within the experiment's run list for use
when an assay is repeated. For more information, see

The ZE5 electronics process the PMT signals to deliver data to Everest Software for analysis.
WARNING! Shock hazard! Due to potential shock hazard, only qualified, trained
technicians should carry out service work on electronic components.

Pre-Amplifiers

Pre-amplifiers boost the signals coming from the PMTs.

Analog-to-Digital Converters

Analog-to-digital converters (ADCs) convert the electrical signal coming from the pre-amplifier into a
digital signal and transfer that signal to the software for data visualization. The ZE5 Cell Analyzer is a
fully digital instrument, transforming signals with 24-bit resolution for signal area and height as well as
17-bit resolution (using linear interpolation at half height) for signal width.
