HP 83712B Synthesized CW Generator, 10 MHz to 20 GHz

The HP 83712B synthesized CW generator sets a new standard for performance at a price that is surprisingly affordable. No longer will you have to give up frequency coverage, modulation or reliability to meet your budget. This signal source will perform beyond your expectations at a price within your reach. Fundamental oscillators and switched low-pass filters deliver <-55 dBc harmonics, eliminate subharmonics and suppress spurious to <-60 dBc. This signal source provides 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).

[ Features ]

High stability time base for frequency accuracy
Low SSB phase noise for out-of-channel tests
High power output for driving the LO port of mixers
Low output power with option 1E1 for receiver sensitivity and SINAD measurements
