The Agilent/Keysight Technologies 83572A 26.5 to 40 GHz, Sweeper Plug-in, Refurbished extends the frequency coverage from 26.5 GHz to 40.0 GHz with 100 MHz frequency accuracy. The plug-in offer minimum unleveled output power of 3 dBm. The output power has a calibrated range of 7 dB. The power level may be manually set to a 0.1 dB resolution, or the power level may be remotely HP-IB programmed to a 0.01 dB resolution. In addition to a single output power, these plug-ins also have a power sweep function. This function sweeps the power from one level to another over an 7 dB for 83572A. Another important feature that these plug-ins offer is slope compensation. This compensates for high frequency power losses in external tests by attenuating the power at lower frequencies.
