Dranetz 305PA3005

The 305PA3005 High Frequency Plug-In is designed for high accuracy to 11MHz. Using a self-tracking oscillator, the input signals are converted to 40kHz for precision measurement by the mainframe. Input attenuators (50-ohms) are provided with 10 dB steps, to cover a range of 1 mV to 3 V rms in either channel. Front panel lamps indicate when input levels are out of range or when level controls are improperly set. The self-tracking oscillator can be controlled by channel A signal, or by a third (independent) signal.
