Positive and negative inputs of the differential amplifier are used to reduce On circuit layout and source or cable characteristics connected to the input. Selected to match the impedance of the input cable. The RTF module (see section 4.1), prior to digitization. Range of the digitizers will be matched by applying an offset to the signal on Zeroing eases the detector tuning procedure by eliminating the need toĬonstantly compensate for an adjustment of the SQUID offset by manually

However, there is an auto zeroing circuit on the ZIP module, The digitizers in the data acquisition system have a range This expected range is a result of two things. The purpose of this circuit is to eliminate voltage differencesīetween input signal grounds and output signal grounds, as well as provide aĪccommodate the expected input from the ZIP. Receive the input signal from the ZIP module Signals from the backplane, via the 25 pin connector, and converts them to a single ended signals referenced to analog Module, by an INA103K instrumentation amplifier. Each of these signals is receivedĭifferentially, via a 25 pin "D" connector located at the rear of the ZIP module four phonon signals and two charge signals. The RTF module's multifunctionality is reflected in its name. Phonon) module and the DAQ (Data AcQuisition) system. Module provides an interface between the ZIP (Z-sensitive Ionization and
