SDRplay RSP1B 1 kHz – 2 GHz
14-bit SDR receiver from 1 kHz to 2 GHz, 10 MHz visible bandwidth, steel case, bias-T
The SDRplay RSP1B is the improved version of the popular RSP1A: a wideband SDR with a 14-bit ADC that seamlessly covers the spectrum from 1 kHz to 2 GHz and lets you monitor and record up to 10 MHz at a time.
Product description
It is housed in a sturdy black-painted steel case and offers better noise performance below 1 MHz and in the 3.5–5.5 MHz, 50–60 MHz and 250–320 MHz ranges, as well as better signal handling on HF.
More preselection filters reduce spurious signals, and the AM/FM and DAB broadcast band notch filters, switchable from software, limit intermodulation caused by strong signals. The 4.7 V bias-T, software-selectable, powers a remote antenna preamplifier.
All you need is a computer and an antenna. It can be used free of charge with SDRuno for Windows and SDRconnect for Windows, macOS and Linux; drivers and documented APIs also support Android and Raspberry Pi 4/5 and many third-party digital decoders. It is powered from the USB cable with a Type-B socket.
The SDRuno software offers multiple virtual receivers to demodulate different signals in the same band simultaneously, selectivity filters with over 140 dB rejection, adjustable dual-stage AGC, notch filters down to 1 Hz with Notch Lock, synchronous AM with selectable sideband, noise reduction, FM AFC, calibrated S-meter, RDS with DX mode and CAT and Omnirig control.
