HP 1.0mm Interchangeable Probe - Order Code HPM1/1
All dimensions are in mm. All probes are hand made and as such there is always some variation between individual devices. Please contact us if the actual dimensions are critical to your work.
Description
This probe has outstanding sensitivity and is ideally suited to the measurement of lower frequency fields. However these probes can be used for higher frequency measurements (particularly of very weak signals) but in such situations the inherent directivity and spatial averaging characteristics of a 1mm aperture means that care should be taken in interpreting data.
Specification
| Output Impedance: | 27pF+/- 4pF |
| Typical Probe Sensitivity: | 850nV/Pa (equivalent to -241.4dB re 1V/uPa) at 3MHz when measured at the output of a correctly terminated HP1 Submersible Preamplifier |
| Sensitivity Tolerance: | Sensitivity variation between individual probes is approx. +/-3dB |
| Typical Frequency Response: (as defined by IEC 60866) | Class A (+/-2dB): 3 to 12MHz Class B (+/-4dB): 200kHz to 15MHz |
| Sensor Material: | 28 micron thick gold electroded Polyvinylidene fluoride (PVdF) film |
| Sensor Dimension: | 1.0mm diameter disc |
