5.1 Overview
Figure5.1: HPPR/2 Standard Configuration
The High Performance Preamplifier version 2 (hereafter referred as HPPR/2) consists, in the
basic configuration, of a 1H module, a XBB module, a 2H module, a cover module (hereafter
referred as Cover2) and a baseplate (HPPR/2 BASEPLATE AV4 4CH or 8CH). The basic
configuration may be updated later to a maximum of nine modules (including cover).
The preamplifier modules contain a Transmitter/Receiver switch including necessary high
performance filters in the transmitter and probe paths, a RF preamplifier and an interface
logic including a power supply and BIS (Bruker Information System). All preamplifier modules
are ‘Fourier capable’.
The LCD-display indicates the operation status and configuration of the HPPR/2, e.g. what
kind of modules are connected, what are their operating modes (observe, lock, wobble,
decouple) and other information.
