Frequently Asked Questions
Have a Question?
-
What power supply requirements does the 150A have?
The 150A requires +9VDC at 150 mA via a 2mm centre-positive DC jack. A universal AC power supply (100-240 VAC, 50/60 Hz) is included with the amplifier. The unit also features ESD and DC power protection on RF inputs and outputs.
-
Can I use individual probes without the amplifier?
Yes, probes can be connected directly to spectrum analysers or oscilloscopes, though signal levels will be lower. The 150A amplifier is recommended for optimal sensitivity, especially when measuring weak emissions or using wide resolution bandwidths for faster measurements.
-
What makes Beehive probes better than DIY alternatives?
Beehive probes feature integrated electrostatic shielding, calibrated sensitivity specifications, professional construction quality, and proven repeatability. Unlike homebrew solutions, they provide quantitative measurements with known accuracy and long-term reliability essential for professional EMC work.
-
Are the probe sensitivity values calibrated and traceable?
Yes, each probe type has specified sensitivity calibration factors enabling quantitative field strength calculations. The sensitivity equations are provided in the technical documentation, allowing you to convert measured power to actual field values in Tesla or V/m.
-
How do I choose the right probe size for my measurement?
Start with larger loops (100C) for general area scanning and sensitivity. Use medium loops (100A) for balanced sensitivity and resolution. Small loops (100B) provide highest spatial resolution for pinpointing specific components. The 100D stub offers pin-level precision for electric field measurements.
-
What frequency range can I measure with this bundle?
The complete system covers 100 kHz to 6+ GHz. Individual probes are optimised for different ranges: 100C for DC-500 MHz, 100A for DC-2.6 GHz, 100B for DC-6+ GHz, and 100D for DC-3+ GHz, providing comprehensive frequency coverage.
-
Can these probes be used with oscilloscopes instead of spectrum analysers?
Yes, the probes work with oscilloscopes using FFT mode, though spectrum analysers provide better dynamic range and frequency resolution. The 150A amplifier's low noise performance makes it suitable for both oscilloscope and spectrum analyser applications.
-
What's the difference between H-field and E-field probes?
H-field probes (100A, 100B, 100C) detect magnetic fields and are most sensitive to current flow in traces and components. E-field probes (100D) detect electric fields and respond to voltage changes. Both types are essential for comprehensive EMC analysis.
-
How does the 150A amplifier improve EMC measurements?
The 150A provides 20-30 dB sensitivity improvement depending on your spectrum analyser model. This enhanced sensitivity allows you to widen the resolution bandwidth, resulting in faster sweep times and more efficient EMC debugging whilst maintaining excellent measurement accuracy.
-
What's included in the Beehive EMC Probe/Amplifier Bundle?
The bundle includes the 150A EMC probe amplifier, four EMC probes (100A medium loop, 100B small loop, 100C large loop, 100D electric field stub), user manuals, and a one-year warranty. The 150A provides 32 dB gain from 100 kHz to 6 GHz with low noise performance.
