SDR
This is an RTL SDR blog software defined radio receiver with RTL2832U ADC chip, R820T2 tuner, 1PPM TCXO, SMA F connector and aluminium case with passive cooling. Tunes from 500 kHz to 1.7 GHz with up to 3.2 MHz (2.4 MHz stable) of ( HF works in direct sampling mode).
Perfect for use as a computer based radio scanner with free software like SDR#, HDSDR, SDR-Radio, GQRX or SDR Touch on Android. Works on Windows, OSX, Linux, Android and Computers like The Raspberry Pi.
Great for many applications including general radio scanning, air traffic control, public safety, ADS-B aircraft radar, marine AIS, ACARS, trunked radio, P25/MotoTRBO digital voice, POCSAG, weather balloons, APRS, NOAA APT/ Meteor M2 weather satellites, radio astronomy, DAB, or as a low cost panadapter with a ham radio.
This RTLSDR model has several improvements over other brands. It uses the improved R820T2 tuner, a 1PPM TCXO, better components, a redesigned lower noise PCB, cooling improvements, extra ESD protection and an SMA F connector. It also has a software activatable bias- Tee for powering LNA's and active antennas. .
NOTE: New units ship with the the new R860 tuner. However, please note that the R860 is exactly identical to the R820T2, the chip factory just changed the name.
HF/VHF/UHF antenna standing wave analyzer. (2022 upgrade of NanoVNA-F)With the following improvements:
1. The user buttons are changed to a rotary encoder, which makes the control more convenient and smooth.
2. New added RTC circuit, with real-time clock and perpetual calendar functions.
3. Optimize the S21 insertion loss/filter measurement performance, with a larger dynamic range.
Running firmware version: 1.0.4, new features:
1. Add RTC real-time clock, perpetual calendar function
2. The measurement data file name is in the form of YYMMDD_HHMMSS.
3. The frequency setting can choose the start and end or the center span mode.
4. The boot sound can be turned on or off.
This is a vector network analyzer, which can measure the S-parameters of the circuit, transmission test, reflection test, insertion loss, return loss, fault location (TDR function), antenna standing wave, impedance, filter response and so on.
Nominal Frequency: 10k - 1.5GHz
Scan Points: Up to 301 points
Battery capacity: 5000mAh/3.7V
Memory capacity size: 16MBUp to about 1000 sets of snp file data can be saved.
Special reminder: The working principle of the resistive touch screen is mainly to realize the operation and control of the screen content through the principle of pressure sensing. Installing a screen protector may have some impact on the operation of the touch screen, we recommend that you do not install a screen protector unless it is necessary.
