RF Power Probe

The new probe RF-SNMP is the evolution of the ANT 131 Precision RF Power Probe. In addition to the precision that has always distinguished the ANT131 probe, RF-SNMP is easy and very quick to install.

It does not require any power input connection, in fact the new RF-SNMP is powered through the LAN cable via POE (Power over Ethernet) and all adjustments are performed via SNMP or web page.

Very high measurement precision and very wide dynamic range make this probe the best choice for transmission systems measurements both at the transmission and at the reception end. RF-SNMP is designed for precision measurement of analog as well as digitally modulated signals. The dynamic range is more than 50dB and its bandwidth is extremely high.
