SPECIFICATIONS

Choose the sensing orientation first, then compare frequency coverage and spatial resolution. HH probes use a horizontal magnetic coil. HV probes use a vertical magnetic coil. E150 uses a horizontal electrode for electric-field scans. The ICR 03 kit lets you select three ICR probes for a shared setup.

Horizontal-coil magnetic microprobes (HH)

Model/ Set	Frequency range	Field/ Orientation	Coil ID or electrode size	Spatial resolution	Use
ICR HH100-27 set	1.5 MHz to 6 GHz	H-field / horizontal coil	100 um	70 um	Measure the magnetic component normal to the board with the coil parallel to the surface. Langer lists higher gain at the lower end of the frequency range for this variant.
ICR HH100-6 set	2.5 MHz to 6 GHz	H-field / horizontal coil	100 um	70 um	Measure the magnetic component normal to the board with the coil parallel to the surface.
ICR HH150-27 set	1.5 MHz to 6 GHz	H-field / horizontal coil	150 um	100 um	Measure the magnetic component normal to the board with the coil parallel to the surface. Langer lists higher gain at the lower end of the frequency range for this variant.
ICR HH150-6 set	2.5 MHz to 6 GHz	H-field / horizontal coil	150 um	100 um	Measure the magnetic component normal to the board with the coil parallel to the surface.
ICR HH250-6 set	2.5 MHz to 6 GHz	H-field / horizontal coil	250 um	150 um	Measure the magnetic component normal to the board with the coil parallel to the surface.
ICR HH250-75 set	500 kHz to 2 GHz	H-field / horizontal coil	250 um	150 um	Measure the magnetic component normal to the board with the coil parallel to the surface. Langer lists higher gain at the lower end of the frequency range for this variant.
ICR HH500-6 set	2 MHz to 6 GHz	H-field / horizontal coil	500 um	300 um	Measure the magnetic component normal to the board with the coil parallel to the surface.
ICR HH500-75 set	200 kHz to 1 GHz	H-field / horizontal coil	500 um	300 um	Measure the magnetic component normal to the board with the coil parallel to the surface. Langer lists higher gain at the lower end of the frequency range for this variant.

Vertical-coil magnetic microprobes (HV)

ICR HV500-75 set	200 kHz to 1 GHz	H-field / vertical coil	500 um	300 um	Measure a magnetic component parallel to the board. Rotate about the scan axis to compare directions. Langer lists higher gain at the lower end of the frequency range for this variant.

Electric-field probe and configurable kit

Kit photo	Model/ Set	Frequency range	Field/ Orientation	Coil ID or electrode size	Spatial resolution	Use
	ICR 03 set	Depends on the three selected probes	Choose H-field or E-field	Depends on probe choice	Depends on probe choice	Select three ICR probes with a shared bias tee and cable.
	ICR E150 set	7 MHz to 3 GHz	E-field / horizontal electrode	(150 x 35) um	65 um	Map electric near fields on IC packages and pins.

Measurement setup

Use a compatible positioning system and receiver or spectrum analyzer. The BT 706 bias tee powers the integrated preamplifier. Use the correction data supplied with the probe, and keep scan height and orientation consistent when comparing designs.
