This modification reference correction to (v); (vi); (xii) under the description. (v) Contract Line Item Number (CLIN) 1, is an NMR Spectrometer, 1 each. (vi) The NMR Spectrometer console shall be compatible with a Spectrospin 89mm vertical bore 7.05 Tesla superconducting magnet and with existing Bruker probes. The spectrometer shall be capable of performing high resolution CPMAS experiments on solid samples, high resolution, multidimensional experiments in solution, and magnetic resonance imaging on samples up to 25mm in diameter. Two frequency channels are required, with the capability of the addition of more channels. Each channel shall be capable of operating both asynchronously and synchronously, with digital generation of offset frequencies and phases. Each channel shall be capable of providing shaped pulses via modulation and attenuation of the frequency synthesizer output. The proton transmitter shall operate at 300 MHz and shall be capable of simultaneously performing excitation and decoupling applications requiring multiple power levels. The proton transmitter shall provide up to 100 W in pulsed operation with an attenuation range of 110 dB. Capability for utilization of an existing Bruker MSL 1kW high power amplifier shall also be provided. The X frequency transmitter(s) shall be capable of providing up to 300 W output power in pulsed operation with an attenuation range of 110 dB. Capability for utilization of an existing Bruker MSL 1 kW high power amplifier shall also be provided. The receiver system shall be capable of digital oversampling and digital signal filtering. An X,Y,Z gradient control system including pre-emphasis and gradient current amplifiers or capability of utilizing an existing Bruker MSL gradient control system shall be provided for micro-imaging applications. Communication between the data acquisition processor and the NMR workstation shall be through a dedicated Ethernet/NFS link. The data acquisition processor shall be capable ofcommunication with an existing 64 bit UNIX base operating system on a Silicon Graphics Indigo 2 platform. (xii)FAR 52.212-5, Contract Terms and Conditions Required to Implement Statutes or Executive Orders -- Commercial Items, applies to this acquisition. The following FAR clauses cited in 52.212-5 are applicable to this acquisition: 52.203-6; 52.203-10; 52.219-8; 52.222-26; 52.222-35; 52.222-36; 52.222-37; 52.225-3; 52.225-9. (0239)
