How to perform a MIL-STD-461 RS103, radiated susceptibility, electric field[edit]
This application note explains how the MIL-STD-461 RS103, radiated susceptibility, electric field test can be performed with RadiMation®
The exact requirements and test methods for the RS103 are specified in the MIL-STD-461.
Necessary equipment[edit]
The following devices are necessary to perform the CS109 test:
- Signal generator
- Amplifier
- Antenna
- Field probe
Define the test level[edit]
Create a correction file for the test level[edit]
-
File
- New
- Correction
First create a correction file in RadiMation® and specify the test level (See 'Table XI RS103 limits.').
- File
- Save correction
Store the test level as correction file on disk.
This correction file with the test level will be used during EUT testing.
EUT Testing[edit]
EUT Testing equipment[edit]
The configuration of the eut test site should contain the following devices:

Configure the EUT test[edit]
To perform the test on the EUT, create a radiated immunity multiband test.
Create a test setup configuration file for the following frequency ranges:
| Frequency range |
Frequency step |
Polarization
|
| 2 MHz to 30 MHz |
1% |
Vertical
|
| 30 MHz - 18 GHz |
0.5% |
Both (Horizontal and vertical)
|
| 18 GHz - 40 GHz |
0.25% |
Both (Horizontal and vertical)
|
The radiated immunity multiband test, can be configured by selecting from the menu:
- Tests
- Radiated Immunity
- Multiband
 Start
|
The start frequency of the test. For example 2 MHz.
|
| End
|
The stop frequency of the test. For example 30 MHz.
|
| Frequency Step
|
The frequency step, see Table III.
|
| Dwell Time
|
The dwell time.
|
| Frequency Change Mode
|
Constant.
|
| Modulation
|
The modulation to use see below.
|
| Test equipment
|
The equipment needed for the radiated susceptibility test.
|
| Location Type
|
Antenna height, distance, polarization and angle.
|
| Test Level
|
Specify the Electrical field closed loop method test level. Also configured a "Variable field"
|
| Inputs
|
No inputs are needed.
|
At TestLevel click Add to add a new Test level and select TestLevel - Electrical field closed loop method
| Description
|
The description of the test level.
|
| Test level
|
Variable field, and specify the correction file for the applicable test level. When the level is one value this value can be specified with Constant field
|
| Tolerance
|
Specify the tolerance to use.
|
| Probes
|
Check Probe 1 to measure with the first probe.
|
To configure the pulse modulation settings click Config next to the modulation settings, click the PM tab, and enter the pulse modulation settings as defined in 5.21.3.4.c.1.a
| Activate modulation
|
Check this checkbox to enable the pulse modulation.
|
| Frequency
|
The PM frequency 1 kHz.
|
| Duty Cycle
|
A duty cycle of 50%.
|
| Also apply modulation out of the dwell-time period
|
Check this checkbox to enable modulation outside the dwell-time.
|
When all settings are configured press Start Test to run the test.
