Beehive 110A – Probe Cable

• An integrated electrostatic shield in the loop probes eliminates common-mode pickup
• Probe dimensions optimized for access to tight spaces
• Calibrated sensitivity up to 3 GHz, depending on model. Usable to beyond 6 GHz
• Can be driven by a signal source to generate fields for electromagnetic susceptibility testing

The 110A probe cable is designed to connect the 100 series probes to the 150A amplifier or other instruments. This double-shielded cable has good RF performance from DC to 6 GHz.

Its narrow diameter gives the 110A cable high flexibility, making it convenient and kink-free when using the probes manually.

One end of the cable has a female SMB connector to connect to the probes, and the other end is a male SMA. This allows it to connect directly to the 150A amplifier with no adapters.

The 100 series EMC probes are designed for identifying and fixing EMC problems. The 100A, 100B, and 100C are loop probes and are sensitive to magnetic fields. The 100D is a stub probe and is sensitive to electric fields.

The loop probes have integrated electrostatic shields, providing isolation from common-mode signals. As a result, these probes deliver excellent repeatability. The different loop sizes allow the user to select the optimum probe for a given frequency, providing the optimum sensitivity and spatial resolution.

The 100D stub probe, with its narrow tip, offers the highest spatial resolution. It is ideally suited to tasks such as tracking EMC sources down to the individual pins of an IC.

Because of the planar construction of the probes, even the large loops are only 0.11” thick, allowing the probe to be inserted into narrow seams and gaps.

• Finding sources of EMC emissions problems
• Injecting fields into circuits to identify those which are EMC-susceptible
• Noninvasive probing of RF circuits
• The probes can be used to measure the signals present on an operational PC board. For example, using a preamplifier, the probes can measure the characteristics of an oscillator, such as frequency, sidebands, and phase noise
