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:
| # | Device name | Tab in testsite configuration window | note |
|---|---|---|---|
| Signal Generator | Devices 1 | The signal generator to use | |
| Amplifier | Devices 1 | The amplifier to use | |
| Field Sensor 1 | Field probes | The field sensor to use |
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.
