SuperSpec is an on-chip filter-bank spectrometer designed for wideband
moderate-resolution spectroscopy at millimeter wavelengths, employing TiN
kinetic inductance detectors. SuperSpec technology will enable large-format
spectroscopic integral field units suitable for high-redshift line intensity
mapping and multi-object spectrographs. In previous results we have
demonstrated noise performance in individual detectors suitable for photon
noise limited ground-based observations at excellent mm-wave sites. In these
proceedings we present the noise performance of a full $Rsim 275$ spectrometer
measured using deployment-ready RF hardware and software. We report typical
noise equivalent powers through the full device of $sim 3 times 10^{-16}
mathrm{W}/sqrt{mathrm{Hz}}$ at expected sky loadings, which are photon noise
dominated. Based on these results, we plan to deploy a six-spectrometer
demonstration instrument to the Large Millimeter Telescope in early 2020.
