kTB Manual Noise Generators

Manual Amplitude Adjustable Noise generators covering frequencies from 1MHz to 26.5GHz

The kM3000 Series noise generators offer a convenient, economical, and rugged solution for a wide range of noise testing applications. Designed for both benchtop use and rack-mounted test stations, these instruments are ideal for any setup requiring reliable noise generation across a frequency range of 1 MHz to 26.5GHz.

Featuring manual control via a front-panel rotary attenuator, the kM3000 Series is simple to operate and helps reduce test setup time. Each unit includes a precision noise source that delivers repeatable, symmetrical white Gaussian noise, integrated with an amplifier, attenuator, and power supply.

Typical applications include:

BER Testing (Eb/No, C/N, SNR), Jamming, Jitter Tolerance Testing, GPS Receiver Testing, EMI Testing, and System & Component Validation amongst others.
Custom configurations are available to meet specific customer requirements.
Please contact the factory for pricing and availability.
