Notes:
· Some of these features require latest firmware upgrade, please upgrade your unit from www.rf-explorer.com/download page.
· Models with two connected modules includes two RF SMA connectors. In such case, some differences may apply when comparing left or right SMA connector. This table above include clear details on which is applicable to each connector.
· (*) This feature or range extension is available with an Expansion Module installed, such as RFEMWSUBxG or RFEM2.4G
· (**) Note some frequency ranges may have a more limited, lower measurable range. Please contact us for more details on a particular frequency range if you need to measure input power close to -10dBm. In all cases, using a 20 or 30dB attenuator is suggested in order to lower the input power to a -30 or -40dBm range, as it will exhibit better behavior by limiting spurious and signal overload. If you use an attenuator, you also improve the VSWR of the measurement and can be adjusted in OffsetDB parameter of RF Explorer ATTENUATOR MENU in order to read the exact value on screen, saving you from doing any math.
· (i) The Expansion Module is already installed in this module and therefore there is no room for additional expansion.
In addition to that, RF Explorer can fit an optional Expansion Module for further band coverage and enhanced capabilities. You can combine any RF Explorer model with any Expansion Module you wish. The firmware will correctly recognize your configuration and will work in all cases.
Assembling an Expansion Module to your RF Explorer is very easy, check this article for more details and contact us if you need additional information.

Note: All 2.4GHz models support now an extended frequency band from 2350 to 2550Mhz by a simple firmware upgrade to v1.08 or newer.
Note: WSUB1G and WSUB3G models can work with frequency span higher than 100MHz (up to 600MHz) by a simple firmware upgrade to v1.11 or newer.
Compliance
All RF Explorer models are complaint with FCC as well as CE regulations.
All RF Explorer Wideband models have been certified under EN/IEC61236 and EN/IEC61000.
All RF Explorer models are RoHS compliant

Comments
We do not know yet, we are trying an approach that should make it compatible, but it is still too early to tell.
However, the 433M, 868M or 915M models includes a narrow band filter and therefore only the specific frequency band goes to the unit - the device is better isolated from out-of-band signals than the WSUB1G is.
Besides that, the 868M and 915M include antenna that is specific for the band and shows a bit higher sensitivity in that band than the telescopic Nagoya NA773 included in the WSUB1G. For the 433M band, the Nagoya is better than the small whip of the 433M unit.
And last but not least, the 433M, 868M or 915M include signal generator for that band, whereas the WSUB1G does not.
You can get the best of both worlds by ordering a 868M and expand it with a RFEMWSUB1G.
On the other hand, the WSUB1G has a single double balanced mixer, whereas the WSUB3G has two. The added loss of the second mixer is the cause of WSUB3G showing a DANL of -105dBm when compared to WSUB1G of -115dBm. So in the specific frequency range covered by WSUB1G (240-960MHz), the WSUB1G module outperforms the WSUB3G sensitivity by about 10dB. As we understand that frequency range is of particular interest to many Audio and Mobile RF professionals, the 3G Combo unit includes both the WSUB1G and WSUB3G so you get the best of both worlds.
1. how many bars on battery indication should show ater 10 hour charge? Not all bars showing.
2. Would be useful to be able to adjust RBW.
thanks
