The 1211-C is an updated version of 1211 unit oscillator series. Along with updated form factor for rack installations its distortion figure has improved. It features both variable capacitance and inductance for frequency control in two bands. The Type 1211-C like most "Unit" instruments requires an external power supply. | The 1211-C is an updated version of 1211 unit oscillator series.
