The Tektronix SG505 is a ultra-low distortion oscillator plug-in for the TM500 system.
Option 01 adds an intermodulation test signal function.
Option 02 adds a fully balanced output to +28 dBm and selectable source impedance with corresponding changes to the front panel connections. It also includes Option 01.
