Length, excluding connector: 6.35" (161 mm)Tip thickness: 0.11" (2.8 mm)Tip diameter: See next to photos. The following curves show the measured output power into 50 ohms for a 1 uT rms field. It can also be computed from the equations below the figures. 
Loop Probes (EMC-100A/B/C): This equation is plotted above and is accurate ± 3 dB from DC to the 3 dB frequency listed in the table below. The probes are usable to higher frequencies but the sensitivity is uncalibrated above the 3-dB frequency. The first notch in the frequency response of the probes occurs at the first resonance listed in the table. Output Power = [X + 20*log10(B) + 20*log10(F)] dBm Where B is the rms magnetic flux density in Tesla, F is the frequency of the received signal in Megahertz X is a scale factor from the following table: Loop SizeX3-dB Frequency First ResonanceLarge 85.1 50 MHz 500 MHzMedium 67.1 1000 MHz 2600 MHzSmall 44.4 3100 MHz>6000 MHzElectric Field Probe (EMC-100D): Stub probes tend to be less repeatable than shielded loop probes, due to the presence of common-mode currents flowing on the outer surface of the probe or attached cable. As signals are measured, it is common to see a few dB of variation in output power as the user changes their grip on the probe or the attached cable. Because of this, the sensitivity of the 100D is not guaranteed. Typical sensitivity of the Electric Field Probe is given by the following equation, and shown in the 100D figure above.Output Power = [-113.2 + 20*log10(E) + 20*log10(F)] dBmWhere E is the rms electric field strength, in Volts/meterF is the frequency of the received signal in Megahertz Integrated electrostatic shield in the loop probes eliminates common-mode pickup. Multiple loop sizes offer optimum sensitivity and spatial resolution at different frequencies.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.
