Model 2854-2 Spike Generator

for MIL-STD-461F CS106 conducted transient susceptibility test

Type 7334-1 Loop Sensor
  DESCRIPTION top of page button

Effective April 2017, we are assigning a new part number to our Solar Model 2854 spike generator and will no longer be manufacturing the Solar Model 2854-1.

We are now offering the Solar Model 2854-2 Spike Generator to continue assisting your testing to MIL-STD-461F CS106.

In short, the specifications, functionality and performance of this updated generator are exactly the same.

Why the change? Solar Electronics Company designed and has been manufacturing our Model 2854-1 since 2008.

Over the years, parts have become harder to find or even obsolete. To continue to provide this quality EMC generator, we redesigned the internal circuitry and updated components. This redesign prompted the part number change and will result in improved reliability, ease of service and better availability of parts.

What hasn’t changed: There will be no discernible difference to you, the end user. This generator meets the same specification with the same performance you have trusted for so many years.


The Solar Model 2854-2 Spike Generator is designed for screen room use in making conducted transient susceptibility tests as specified in MIL-STD-461F, Test Method CS106.

The Model 2854-2 provides 5 μS ±22% pulse with a 1.5 μS ± 0.5 μS rise time across a 5.0 Ω non-inductive resistor. Voltage is adjustable to greater than 400 V. The undershoot is limited to less than 120 V peak (maximum) and less than 20 μS. The repetition rate is variable and can be adjusted from 0.8 pulse per second to 10 pulse per second. Single transients can be applied with the pushbutton on the front panel.

Two sets of output terminals allow either parallel or series injection into the power line. The series injection may be used on DC and AC lines. Parallel injection should be used on DC lines only. The output winding used for series injection can carry 25 A of power current. The output terminals are isolated from the chassis and the power cord.

Provides output levels from 10 V to more than 400 V into 5 Ω
Adjustable pulse position on AC lines relates the transient susceptibility to real
  time aspects of digital systems
Single pulse feature for controlled isolation of transient effects
Output terminals for series and parallel injection
Standard rack panel construction: 19" wide x 7" high x 12.75" deep (48.26 cm x 17.78 cm x 32.38 cm)
