The light weight, compact size and low cost DSA800 family of spectrum analyzers from Rigol Technologies feature digital IF technology to provide the reliability and performance necessary for RF applications. The spectrum analyzers have a frequency range of 9 kHz to 1.5 GHz with a typical displayed average noise level (DANL) of ‑135 dBm. SSB offset phase noise is typically -80 dBc/Hz at 10 kHz, and the resolution bandwidth is adjustable from 100 Hz to 1 MHz. A preamplifier and AM/FM demodulation are standard with this instrument.

Hacking the Rigol DS1052E Oscilloscope with Linux, hardwarehank writes – [via]
I was in the market for an oscilloscope, but I didn’t want to spend much. I found out about Rigol and their line of $300-400 scopes, and was getting ready to buy one. Then I found a post on how to make your DS1052E, which costs about $400 into a DS1102E, which costs about $700 with a simple firmware modification! I bought the scope right after, and I received it in the mail today. It’s pretty nice by default, but doubling the bandwidth is always a plus.
The DS1052E has a 50Mhz maximum frequency, but it has exactly the same hardware (as far as the reverse-engineering folks can tell) as the DS1102E, which has a 100Mhz maximum. This guide will show you how to make the switch very easily using Linux. You can do it in Windows too, but it’s a bit more involved, and Linux makes it really really easy.
