John Fluke, Model 410B-AT, Power Supply (fig. 1-19) is capable of providing an output of 0 to 10,000 V dc at 0 to 10
milliamperes. The output voltage is selected by four decade switches and a vernier potentiometer. The instrument may be
operated with either positive or negative output terminal grounded, as selected by a front-panel switch. Over-current
protection is provided to return the supply to standby operation in the event of excessive load current.
Figure 1-20. Hewlett-Packard, Model 652A, Audio-Radio Frequency Oscillator. Hewlett-Packard, Model 652A, Audio-
Radio Frequency Oscillator (fig. 1-20) is a stable, capacitance-tuned oscillator that has a frequency range of 10 Hz to 10
MHz. The oscillator has a sine-wave output that is adjustable from 10 microvolts to 3.16 volts into 50 or 600 ohms.
