High Performance RF Signal Generators

Giga-tronics Incorporatednd 6082A synthesized RF signal generators provide good spectral purity. Phase noise at 1 GHz is -131 dBc/Hz at 20 kHz offset. Non-harmonic spurious performance is -100 dBc at 1 GHz. Residual FM is a low 1.5 Hz, which is suited for both high performance receiver test and LO substitution. The output level of +19 dBm (+20 dBm with overranging) provides the power you needed for receiver overload tests, LO substitution, and for driving high level mixers. At -140 dBm (-147 dBm with underranging), generators are suited for receiver sensitivity or noise figure measurements. Low RF IMD makes both instruments suited for receiver selectivity or SSB two-tone testing.

AM, FM, phase and pulse modulation are all available, and can be combined for complex signal simulation. FM deviation to 8 MHz, plus rates from dc to 100 kHz, provide the versatility needed to test mobile, cellular and military communications, as well as pagers and surveillance receivers. Pulse rise time is <15 ns (<7.5 ns typical). While the on/off ratio of the 6082A is 80 dB, making it suitable for a host of radar component testing applications. The internal modulation oscillator makes it possible to produce pulse waveforms phase-locked with the RF carrier.
