The 305PA3001 Phasemeter Autoranging Plug-In is designed for use with the 305 Phasemeter Mainframe and features high accuracy over a broad range of input levels and frequencies. Auto-ranging of gain in each channel assures high accuracy (0.05? guaranteed) over a dynamic range of 60dB (50mV to 50Vrms) for independent levels of inputs, with a useful range of 90dB (10mV to 300Vrms). This plug-in covers the range from 2Hz to 700kHz, with its highest accuracy in the 50Hz to 50kHz range. The unit also features compatibility with Textronix probes and includes front panel lamps to indicate when either input signal is below 50mV or above 50 V rms.
