HP / Keysight / Agilent 83731A Overview
You can count on the 83731A for excellent spectral purity. Fundamental oscillators and switched Iow pass filters deliver < - 55 dBc harmonics, eliminate subharmonics, and supress spurious to < -60 dBc. Not only does the HP 83731A provide plenty of output power (typically > +14 dBm), but spectral purity is maintained even at these high power levels. Typical output power at frequencies below 1 GHz is + 20 dBm. Level resolution is 0.01 dB with typical accuracy of -+ 1.0 dB at any frequency or power level. User Level Correction simplifies generating accurate, leveled power at distant test ports.
