As power meters, the 5347A and 5348A offer excellent dynamic range, linearity and accuracy.They use the same proven power sensors used with Hewlett-Packards standalone power meters. Power sensors and accurate, wide-range measurements go hand in hand. Power measurements can be made from -70 dBm to +20 dBm over a 10MHz to 26.5 GHz frequency range, depending on the sensors used. Exceptional power-meter linearity and low sensor SWR combine to give you outstanding measurement accuracy. The instrumentation accuracy is +/-0.5% in linear mode or +/-0.02 dB in logarithmic mode, making power meter uncertainty a negligible part of your total measurement error.
The frequency counter performance rivals that of HPs highest performance standalone CW microwave counters. The HP 5347A measures frequency from 10Hz to 20 GHz; the HP 5348A from 10Hz to 26.5 GHz. You can select either 1 Hz or 10kHz resolution while measuring signals down to -35 dBm.
