MIL-STD-461 CS115 Rentals - Impulse Excitation Equipment

General Testing Information

MIL-STD-461 CS115 applies to all aircraft, space, and ground system interconnecting cables, including power cables. This section of MIL-STD-461 can be applied as well to surface ship and submarine subsystems and equipment. The purpose is to test an electronic or electrical system to withstand signals coupled onto EUT associated cabling. The EUT will be subjected to rise and fall times, pulse width, and amplitude as specified on Figure 1 at a 30 Hz rate for one minute. The needed equipment for testing to this standard includes a pulse generator, current injection probe, drive cable, current probe, calibration fixture, oscilloscope, attenuators, coaxial loads, and LISNs. The CS 115 standard defines the result of testing by "The EUT shall not exhibit any malfunction, degradation of performance, or deviation from specified indications, beyond the tolerances indicated in the individual equipment or subsystems specification..".

1. Pulse Generator, 50 Ohm, Charged Line
2. Current injection probe
3. Drive cable, 50Ohm 2 meters .5dB or less loss
4. Current Probe
5. Calibration Fixture
6. Oscilloscope 50 Ohm Input impedance
7. Attenuator 50 Ohm
8. Coaxial Loads 50 Ohm
9. LISNs

Test Setup

Test Solutions

MIL-STD-461 CS115 test equipment is broken down by the pulse generator and test setup. The generators that we carry for compliant solutions include the EMC Partner MIG 2000-6 and Solar Electronics 9355. Both of these systems provide the required waveforms and offer full test accessories setup. With the large amount of overlap between 115 and CS116, the test setups can be used interchangeably for either. The pulse generators and associated test accessories can be either rented individually for this standard or for multiple standards allowing for a more cost efficient test solution.
