The General Radio 1219-A Unit Pulse Amplifier was introduced in Catalog O (1956) and remained available through Catalog Q (1961).
A companion device for use with Types 1217-A and 1391-B pulse generators, Type 1219-A is designed to increase the power level but preserve pulse characteristics.
A front-panel switch matches the output of the amplifier to the load, with several common transmission line impedances being available. This switch is pulse polarity sensitive.
Although a unit instrument, the 1219-A it contains its own power supply.
Specifications
- Output Pulse Voltage: varies between 10 and 250 V
- Output Impedance Positive Pulse: 50, 75, 100, 150 Ω, all ±10%
- Output Impedance Negative Pulse:50, 75, 100, 150, 200, 250, 300 Ω, all ±10%; 570 Ω ±20%
- Output Current: depends upon the position of the duty-ratio selector switch and the duty ratio
- Input Impedance: Approximalely 50 kΩ shunted by 30 pF
