E-band Spectrum Compact is an ultra-light and easy to use measurement solution for the 70 - 87 GHz microwave frequency band. This battery powered device does not require external down-converters, and is a must-have tool for any field engineer performing E-band equipment installation, link troubleshooting, site planning and maintenance. The instrument utilizes a resistive touch screen for ease of use in the field, allowing the engineer to wear gloves when using the device. Furthermore, its high sensitivity and low noise floor make it possible to detect even exceptionally weak signals. The Spectrum Compact can also be used for high precision detection of existing interference on installed paths or available radio channels.
