The EM-4310 Spike Generator is a transient event generator designed to create high amplitude, narrow width pulses which are coupled onto AC or DC power lines as specified by Method CS06 and RS02 of MIL-STD-461 and MIL-STD-462.

A typical electrical transient rises quickly to a peak value and then decays exponentially to zero. After the spike voltage decays to zero, the waveforms exhibit a ringing characteristic that depends on the load connected to the spike generator.

The amplitude of the output spike is variable from 0 to 600 V peak. Three different pulse widths are available: 10.0µs, 5.0µs, and 0.15µs. Pulse width is defined as the time required for the output pulse (spike) to rise to a peak value and decay to zero.

The EM-4310 can inject spikes onto AC or DC power lines in variety of modes: asynchronous, synchronized, or single pulse.



Output: Amplitude Adjustable 0-600 V peak minimum into 5-ohm non-inductive load at rates of 10 PPS or less.
NOTE: Maximum output voltage will decrease at rates greater than 10 PPS.
Output Pulse Widths: 10.0 µs, 5.0 µs, 0.15 µs ±20% into 5-ohm non-inductive load.
NOTE: The polarity of the 0.15 µs pulse is REVERSED with respect to the 10.0 µs and 5.0 µs pulses.
Amplitude Display: LED Display, accuracy ±5%. Indicates peak amplitude of output spike as measured into a 5-ohm noninductive load.
Pulse Repetition Rate:
SYNC Mode:
Internal/External: 1-10 PPS
Free Run Mode:
Internal: 0.5-50 PPS
External: >0-50 PPS
Single Pulse Mode: Manually generated, pushbutton.
Pulse Positioning: Positioning range of 1 to 10 PPS pulse is adjustable over 360° range of power frequencies from 50 to 800 Hz when in SYNC mode.
