either direction under manual control. Voltage
at motor shall have a step waveform with rise
time less than 100 microseconds).
DC power supply (regulated, variable voltage,
15 to 42 volts, O to 10 amperes (minimum).
The effective source impedance shall not exceed
0.02 ohm).
Vacuum tube voltmeter (de), O to 1.0 vdc;
Input resistance: greater than 50 megohms;
Accuracy:
