Description
This product is available to buy direct through our secure online shop.
Although optimised for lower frequencies, these probes can be used for higher frequency measurements (particularly of very weak signals). In such situations the inherent directivity and spatial averaging characteristics of a 2mm aperture means that care should be taken in interpreting data.
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.
