Find Your Exact-Fit RF Recorder

Choosing an RF recorder can be complicated, but it doesn't have to be. We offer many configurations and customizations. We're happy to advise you on which is best for your needs.

Model 3863

Record and play two synchronized RF channels

Model 3863 allows you to capture and reproduce two RF channels anywhere in the spectrum between 30MHz and 26.5GHz. You can configure the two channels to be time aligned, phase coherent, or fully phase aligned. This instrument is perfect for analyzing interactions between signals in different parts of the spectrum or stimulus-response applications.

30MHz to 26.5GHz tuning range

1GHz/channel continuous IQ streaming

2GHz/channel short duration IQ capture

Signal Trove™ storage options to support minutes, hours, or days of signal record & playback

Model 3823

Record one wideband RF channel in a congested spectral environment

Model 3823 allows you to record a wide block of RF spectrum using a single RF channel. The super-het RF downconverter architecture and built-in LNA is optimized to retain signal quality in the most difficult and congested spectral environments. Additional RF pre-selector options allow you to knock down large out-of-band interferers and really dial in your recordings for maximal fidelity.

20Hz to 26.5GHz tuning range

320MHz record bandwidth

Super-het architecture with LNA

Signal Trove™ storage options to support minutes, hours, or days of signal record & playback

Model 3865

Generate eight phase-coherent arbitrary waveforms at RF frequencies

Model 3865 is unlike any other RF signal generator you’ve ever used. This instrument can simultaneously stream eight different arbitrary waveforms to eight independent RF output channels. Each arbitrary waveform can be minutes or hours in duration. Choose the phase-aligned option to create tightly aligned beams across wide bandwidths.
