Avance II is series of Bruker BioSpin Group produced Avance NMR spectrometers (consoles) with up to 8 (?) RF (Radio Frequency) channels, plus lock channel. This console has a improved version Avance II+ also. It is/was produced for NMR spectrometers from 200 to 900 (950) MHz. Around 2008 it is replaced with Avance III series of consoles. The main difference of Avance II from earlier Avance series of spectrometer consoles is introduction of the DRU (Digital Receiving Unit) in it and the larger integration of different spectrometer functions into a one physical block (device). It uses oversampling for the signal analog-digital conversion, and digital lock system. For the console operation Bruker TopSpin software is needed. Frequency generation with error <0.005 Hz for frequency and <0.01 deg for phase. Timing resolution (for operations) 12.5 ns
Avance II console can be implemented in three different chassies: MicroBay (only 200-400 MHz and up to 3-channel configuration), OneBay (up to 600 MHz?) and TwoBay (Up to 900 MHz and for MAS). The main parts of the Avance II console are AQS (AQuisition System) or AQS/2 and BSMS/2 (Bruker Smart Magnet System). In TwoBay configuration two AQS-s modules can be installed simultaneously.
In AQS/2 are located the (main) devices (blocks): ACB (Aquisition Control Board), DRU, RXAD (receiver with integrated analog to digital converter), REF or REF/2 (REference Unit), SGU (Signal Generation Unit), FCU4 (Frequency Control Unit), TCU3 (Timing Control Unit), GCU (Gradient Control Unit), CCU (Communication Control Unit), PSM1 or 2 (Power Supply Module). AQS/2 can also contain internal amplifiers (BLA2BB, BLAX300), preamplifiers (PREAMP XBB and PREAMP 1H2H), and Router(s). AQS/2 can contain more then one of each of those units.
BSMS/2 contains: ELCB (Extended Lock Control Board) or CPU/3 (Central Processing Unit) plus LCB (Lock Control Board), SLCB (Sample Level Control Board), GAB (Gradient Amplifier Board), PSB (Power Supply Board), SCB13 or SCB20 (Shim Control Board), BVT, L-TX (Lock Transmitter), L-RX (Lock Receiver), 2H-TX (Lockswitch), PNK (pneumatics).
Additionally, depending on configuration, Avance II console chassis can be equipped with various power amplifiers, VTU (Variable Temberature Unit), MAS devices, etc.
To the console external devices, like HPPR or HPPR/2, KBC (keyboard), PC (computer) and others, are connected
