Krytar has developed an accurate RF and Microwave Power Meter specifically for budget minded engineers who have the need to accurately measure CW or swept RF and microwave power. Auto-ranging linearity is ± 0.05 dB. Accurate CW power measurement range is -30 to +20 dBm (useable to -39 dBm). Unit provides a DC output voltage of -3.9 to +2.0 volts which is equivalent to power input of -39 to +20 dBm (allows low cost swept scalar measurements). An optional RS232 serial port or IEEE-488 interface bus is available. The device is completely portable and operates on internal rechargeable batteries that offer greater than 12 hours of operation and include an internal fast battery charger.
