Address your toughest signal requirements with the metrology-grade analog PSG
Test high-power devices and overcome test system losses with options capable of generating more than 1 W (+30 dBm) of output power
Meet test system needs across a wide range—available in 20, 31.8, 40, 50, and 67 GHz models with frequency extender modules to cover up to 1.1 THz
Address the demanding needs of Doppler radar, ADC, and receiver-blocking tests with textremely low phase noise: -91 dBc/Hz at 100 Hz offset and -126 dBc/Hz at 10 kHz offset (10 GHz)
Thoroughly characterize devices and circuits by adding AM, FM, M, and pulse modulation to your test signal
Customize the PSG to meet your needs
Generate continuous wave (CW) signals for LO substitution or swept stimulus response analysis. Optionally add AM, FM, M and/or pulse modulation to accurately characterize RF and microwave components and devices. Many performance enhancement options are also available to configure the signal generator to meet your specific test requirements. Tailor the PSG for today’s RF and microwave test applications and easily upgrade in the future as your needs change.
