Bulk Current Injection Probes
Fischer Custom Communications, Inc. develops and manufactures Bulk Current Injection Probes to meet specific customer requirements and to perform compliance testing in accordance with Mil-Std-461/462, RTCA/DO-160 Section 20 and 22, Bellcore TR-NWT001 089, SAE Jl5447, EN 55101-4 and CSEFA-2 EuroFighter and other susceptibility specifications.
Bulk Current Injection Probe Fixtures
Calibration Fixtures are integral to Bulk Current Injection Test Procedures. Fixtures allow the user to quickly and easily calibrate a Bulk Current Injection Probe prior to performing compliance testing.
Current Monitor Probes
Current Monitor Probes are RF transformers that are used to measure RF current. Current measurements are made by placing a current carrying conductor(s) within the sensing aperture of the probe and measuring the probe s output voltage with an RF detector. Calibration data of the probe is the transfer function of the voltages measured to current.

CISPR 22/32 ISN
CISPR 22/32 defines ISN s as specialized coupling decoupling devices used to measure the conducted asymmetric common mode radio interference voltages of an ITE. Our ISN s meet the requirements of CISPR 22/32 and we offer models for measuring conducted emissions on single, two and four balanced pair telecom ITE s. All meet the requirements for Longitudinal...
Coupling Decoupling Networks (CDN)
Common mode current can be delivered to the EUT using a variety of Coupling Networks to inject the signal onto the unscreened cables, shielded cables, balanced cables, coaxial cables and power mains. Decoupling Networks are used to insure that the disturbance signal does not influence the auxiliary equipment and are placed between the EUT and the auxiliary equipment.
50-150 OHM Adapters
Fischer Custom Communications, Inc. develops and manufactures Bulk Current Injection Probes to meet specific customer requirements and to perform compliance testing in accordance with Mil-Std-461/462, RTCA/DO-160 Section 20 and 22, Bellcore TR-NWT- 001 089, SAE Jl5447, EN 55101-4 and CSEFA-2 Euro- Fighter and other susceptibility specifications.
Capacitive Voltage Probe
Non-contact Capacitive Voltage Probe (F-CVP-1) is used to measure the common mode voltage between a multi-pair balanced cable bundle and the local ground reference for the cable bundle in accordance with CISPR 22/32.
EM Injection Clamps and Fixtures
Electromagnetic (EM) Clamp is a high efficiency broadband clamp-on injection device developed to test the immunity of electronic equipment when the standard IEC 1000-4-6 CDN using the direct capacitive coupling technique is not possible nor appropriate.
DCN
Fischer Custom Communications, Inc. develops and manufactures Bulk Current Injection Probes to meet specific customer requirements and to perform compliance testing in accordance with Mil-Std-461/462, RTCA/DO-160 Section 20 and 22, Bellcore TR-NWT- 001 089, SAE Jl5447, EN 55101-4 and CSEFA-2 Euro- Fighter and other susceptibility specifications.
LISN
A line impedance stabilization network (LISN) is a device used in conducted and radiated radio-frequency emission and susceptibility tests.
Pulsers
Current Monitor Probes are RF transformers that are used to measure RF current. Current measurements are made by placing a current carrying conductor(s) within the sensing aperture of the probe and measuring the probe s output voltage with an RF detector. Calibration data of the probe is the transfer function of the voltages measured to current.
Surface Monitor Probes
Surface Monitor Probe is a half clamp-on probe with a dielectric cover on the sensing window. Surface Probe measures currents on metallic conductors with flat regions such as ground planes, striplines, printed wiring boards, bundles of wire and architectural structures.
Telecom Surge CDN
Surge Coupling-Decoupling Networks (SCDN) are used to couple the surge specified in IEC 61000-4-5 onto active telecom lines to determine if the telecom equipment sustains functional upset or damage due to the surge. The Surge CDN maintains all of its Technical Specifications while delivering the full range of open circuit voltage to short circuit current demanded by the EUT load.
TEM Cell | Stripline
Fischer Custom Communications, Inc. offers a family of Transverse Electromagnetic (TEM) cells that can be used for both emissions and immunity testing.
