The ANT Group is offering the ANT147, a precision, battery-operated RF probe with datalogger.
Similar to the ANT131, it is a stand-alone or rack-mount probe, powered by 9V battery or DC, that can handle analog as well as digitally modulated signals. Dynamic range is more than 50 dB with precision is ±0.5 dB.
Using the fixed pads (3 dB or 20 dB), dynamic range can be shifted, so that high power or low power can be detected. There are two frequency range versions available: 10 MHz – 1GHz or 900 MHz – 2.5 GHz. Dynamic range can be compressed in order to have a better reading from the built-in 0-5V output. It has the features of the ANT131 but includes a datalogger capable of 91 days of logging (1 second samples). Data can be downloaded to the company’s software or Windows Excel or other application that accepts comma-separated data.
