UNITYINOVA Microimaging Module Installing the Preamplifier Attenuator This procedure describes how to install the preamplifier attenuator, which attenuates the output of the observe preamplifier before the signal reaches the single mixer. 1. Position the preamplifier attenuator (00-969935-00) on the floor near the magnet leg. 2. Disconnect cable 00-958298-08 from the observe preamplifier output J5312 and connect it to the preamplifier attenuator output. 3. Use cable 00-958298-03 to attach the preamplifier attenuator input to the observe preamplifier output J5312. Installing Gradient Coils and the Microimaging Probe Refer to the NMR Probes Installation Manual for the following procedures: • Installing gradient coils • Inserting a sample into the microimaging probe • Installing and connecting the microimaging probe Configuring VNMR for Microimaging The microimaging software option can be installed at any time from the VNMR CD-ROM. Refer to the VNMR and Solaris Software Installation Manual for more information. Run config to add gradients, using Table 3 as a guide. (WFG+SDAC refers to the waveform generator and the Smart DAC board.) Table 3.
