The General Radio 1330-A Bridge Oscillator was introduced in Catalog M (1951) and remained available through Catalog 1973.
The Type 1330-A is a wide range Oscillator designed as a generator in bridge service. It can supply 2 fixed frequencies for audio frequency bridges and variable frequency from 5 kHz to 50 MHz for RF bridge measurements. The 1330-A offers amplitude modulation of the variable RF oscillator by the two fixed audio oscillator frequencies. With its totally shielded aluminum case and carrying handles its portable and less expensive than a standard signal generator. The RF compartment is similar in design to the 1001-A with its double shielded removable housing. The panel of the 1330-A can also be rack mounted.
