Broadband Ridged Probes

NSI offers broadband ridged probe (RGP) antennas for use as spherical near-field (SNF) measurement probes and far-field (FF) range illuminators.

The wide bandwidth of these probes allow replacement of several standard Open Ended Waveguide (OEWG) Probes with a single dual ridge horn when crossing waveguide bands thereby eliminating the need to change probes. At low frequencies, these probes are typically smaller than equivalent OEWG probes making testing easier and more convenient.

 

 

Features:

Frequency coverage from 0.2 to 50 GHz
Includes NSI mounting hardware & absorber collar

Includes SNF pattern files (typical) to allow for NSI2000 SNF probe correction
Typical cross polarization < -25 dB
Coaxial connector (f) – connector type depending upon frequency

Note:
• Wider frequency range available when used as a far-field range illuminator.
• Narrower frequency range applies when used as a probe for spherical near-field testing.
• Not recommended for use with planar or cylindrical near-field systems.
• Not recommended for use as a gain standard.
• Only typical probe patterns are provided with probe.
• Probe pattern calibration available as an additional option. Please contact NSI sales for details.
• Due to the mass of some of the lower frequency probes, the probe polarization and/or translation stage on an antenna test system may need to be upgraded or removed. Please contact NSI sales for details.
