The Solar Model 7399-3 Spike Generator is a transient immunity generator capable of providing high energy spikes with amplitudes adjustable up to 2500 V peak into low impedance loads, as required by MIL-STD-1399, Section 300B. The shape of the spike the Solar Model 7399-3 generates approximates Figure 6 of MIL-STD-1399-300B. Solar Model 7399-3 is specified in MIL-STD-1399-300B. A SYNC TEST function is provided for adjusting the trigger circuit of the associated oscilloscope for response to a single pulse. After this adjustment of the scope, it is ready for viewing the spike. When the READY lamp indicates the storage circuit has been charged to the selected peak voltage, the pushbutton is depressed which triggers the sync circuit of the oscilloscope.
Solar Model 7399-3 Modes of Operation:
- Repetitive spikes up to 2500 V peak at two pulses per minute
- Single non-synchronous spike actuated by a pushbutton on the panel
- Sync functions provide for placing the spike on the power frequency waveform of 50, 60 or 400 Hz power lines; the spike can be moved to any point on the sine wave from 0 to 360°
