Near Field Probes

100 kHz to 50 MHz | 4 shielded passive H-field probes | SMB output

Find magnetic emissions from switching power stages, cables and individual IC connections. Start with the LF-R 400 to survey the assembly, then move to the smaller heads to isolate the source.

30 MHz to 3 GHz | 6 passive E-field and H-field probes | SMB output

Survey electric and magnetic emissions with larger heads, then use the fine tips to trace the source to a conductor, component or pin. The RF-E 02 covers 30 MHz to 1.5 GHz.

30 MHz to 3 GHz | 3 passive H-field probes and 1 passive E-field probe | SMB output

Compare electric and magnetic coupling close to IC pins, traces and connectors. The RF-K 7-4 covers 30 MHz to 1 GHz.

30 MHz to 3 GHz | 4 passive H-field probes | SMB output

Start with the RF-R 400-1 or RF-R 50-1 to survey a board or cable. Switch to the angled RF-B 3-2 or U-shaped RF-U 5-2 to trace magnetic coupling near components and conductors.

30 MHz to 3 GHz | 2 passive miniature H-field probes | SMB output

Resolve magnetic-field hot spots with manufacturer-stated spatial resolution under 1 mm. The miniature heads suit dense layouts and detailed measurements near components. Langer recommends an external 20 dB or 30 dB preamplifier for weak signals.

30 MHz to 3 GHz | 2 passive E-field probes | SMB output

Compare electric-field distributions near buses, switching nodes and signal lines. Use the RF-E 02 for a wider survey and the RF-E 05 to narrow down the source.

30 MHz to 6 GHz | 4 passive H-field probes and 1 passive E-field probe | SMA output

Survey emissions through 6 GHz and narrow down coupling paths with dedicated probe shapes. The XF probes include internal termination and impedance matching. Langer reports lower sensitivity at the low end than its RF-series probes.

1 GHz to 10 GHz | 2 passive H-field probes and 1 passive E-field probe | SMA female output

Trace high-frequency emissions and clock harmonics near IC packages, connectors and high-speed interconnects. Compare E-field and H-field responses at the same location to investigate coupling.

1 GHz to 20 GHz | 1 passive H-field probe | SMA female output

Investigate magnetic-field emissions near microwave circuits, conductors and IC pins. The approximately 6 x 6 mm head provides access for close measurements on assembled boards.

Up to 40 GHz | 1 B-field probe and 1 E-field probe | 2.92 mm (K) female output

Compare electric and magnetic near fields on microwave and millimeter-wave assemblies. The kit includes a 40 GHz microwave cable and probe characterization files for use with the supplied ChipScan-ESA Viewer.

Up to 40 GHz | Single electric-field probe for measurements up to 40 GHz (0.2 mm)

Use this passive probe to localize electric fields near microwave circuits and transmission lines. The kit includes probe characterization data and ChipScan-ESA Viewer. Select a 40 GHz-rated cable and measurement instrument for the intended band.

Up to 40 GHz | Single magnetic-field probe for measurements up to 40 GHz

Use this passive probe to localize magnetic fields near microwave circuits and transmission lines. The kit includes probe characterization data and ChipScan-ESA Viewer. Select a 40 GHz-rated cable and measurement instrument for the intended band.
