HackRF这个碉堡了
Posted | archive
以前感谢一位名叫lol的网友得到了两个RTL2832U dongle开始玩rtlsdr
这玩意的参数是:
- 64MHz - 1700 MHz (50 - 2200 MHz also possible)
- Sample rate: 3.2 MS/s
- Resolution: 8 bits/sample
- receive only
关键是很便宜,大概$10左右。
今天无意中又翻到另外一个HackRF更加碉堡了。大概是$300左右价位,DARPA资助,具体参数为:
- transmit and receive
- operating frequency: 100 MHz to 6 GHz
- maximum sample rate: 20 Msps
- resolution: 8 bits
- interface: High Speed USB
- power supply: USB bus power
- open source hardware and software
更喜欢HackRF的原因是其带宽。DMB-TH的带宽是4.813 Mbit/s - 32.486 Mbit/s,所以rtlsdr没法搞这个。
HackRF在github搞软件开源,同时也有硬件开源,很有意思。
