Choose the HP 83711A, 1 to 20 GHz, or the HP 83712A, 10 MHz to 20 GHz, for your applications that demand wide output dynamic range and stringent spectral purity. Fundamental oscillators and switched low-pass filters deliver < - 55 dBc harmonics, eliminate subharmonics, and suppress spurious to < - 60 dBc. The HP 83711/12A provide plenty of output power (typically > + 14 dBm), while spectral purity is maintained even at high power levels (typical output power at frequencies below 1 GHz is + 20 dBm). The HP 83711/12A deliver > 100 dB dynamic range. 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.
The HP 83711/12A are the recommended local oscillators for the 8970B noise figure meter. Low broadband noise minimizes errors in measurements of low gain devices. Use the HP 83711/12A with the HP 83550 Series millimeter wave modules to generate signals to 110 GHz.
All front panel functions are completely HP-IB programmable and SCPI compatible.
The HP 83711 /12A are designed to remain within factory specifications for the entire life of the instrument. The recommended two-year performance verification cycle minimizes downtime and cost of ownership. If a unit ever drifts, automated adjustment routines can be run to return the unit to factory performance in < six hours. Extensive use of surface mount technology and a minimum number of adjustments combine to deliver an estimated MTBF of > 20,000 hours. Built-in functional verification routines speed servicing.
