The Type 650-P1 is an accessory oscillator and amplifier for the Type [[650-A]] Impedance Bridge. Its designed to fit into the empty battery compartment of the bridge. It provides a DC potential and 1 kHz generator for bridge measurements. A built-in amplifier is available for AC detector use. Amplifier gain is variable and a choice of tuned 1 kHz or flat frequency response. The 1 kHz generator output has a variable control. | |||
* '''Caution:''' The DC output terminals have at least 185 V available and are uninsulated! | |||
