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 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 two fixed frequencies for audio-frequency bridges, or a 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, it is portable and less expensive than a standard signal generator. The RF compartment is similar in design to the 1001-A Standard Signal Generator with its double-shielded, removable housing. The panel of the 1330-A can also be rack mounted.

Specifications

  • Frequency Range: 400 Hz, 1000 Hz fixed frequencies; 5 kHz to 50 MHz in 8 ranges
  • Frequency Accuracy: ±5% for the fixed frequencies; ±2% for frequencies above 150 kHz
  • Envelope Distortion: Between 1% and 6% at the 60% modulation level
  • Output Voltage: fixed 12 V at the audio output; RF output is adjustable up to 10 V into 50 Ω
