Source of Signals
CRS+ - Laplace Instruments Ltd.
The CRS+ is a stable and calibrated source of signals which cover the 9KHz - 30MHz frequency range. The fundamental signal is a 15KHz comb and each harmonic is output as a narrowband peak of known amplitude. This signal is output on either the L and N lines, referenced to ground. A switch provides on/off and line selection.
