Signal Generator E

The first of the "E" series low-cost, small sized signal generators widely used in service departments as it covered all radio and television bands.
Range is 0.1 to 60 MHz on fundamentals with a 1% accuracy and constant 75 ohm source impedance.

A: 30 ... 60 MHz
B: 10 ... 30 MHz
C: 3 ... 10 MHz
D: 1 ... 3 MHz
E: 300 ... 1000 KHz
F: 100 ... 300 KHz

The Band A (30 MHz ... 60 MHz) used also for 60 MHz to 120 MHz (harmonic).

Later renamed "Model 1", it used wartime type tubes and is otherwise identical. The Model 2 uses contemporary tubes and increased frequency range.
