908-R96
The General Radio 908-R96 Synchronous Dial Drive was introduced in Catalog O (1956) and remained available through Catalog S (1965).
The Type 908-R96 is a synchronous dial drive with a pinion speed of 4 rpm. Its function is to sweep the dial of the attached instrument at a rate synchronous with a graphic recorder. For X-Y recorder operation an internal 50 kΩ potentiometer (simultaneously sweep) is used for synchronization. The 908-R96 is self reversing when it encounters a mechanical stop. Functions include plotting frequency versus amplitude. Because of the slow 4 rpm pinion speed the Type 908-R96 is not recommended for oscilloscope presentation and not compatible with 907 dials.
Compatible oscillators are 1208-C, 1209-C, 1209-CL, 1211-C, 1215-C, 1304-B, 1305-A, and 1330-A.
