Explorer vs. TTI Spectrum Analyzers
« on: November 17, 2015, 09:06:29 am »

Thought I'd experiment with Explorer.  First impressions vs. TTI.

1. Explorer takes about a minute to do 4 averaged scans of a 60 MHz segment.  TTI takes a few seconds.
2. Explorer needs to be connected to a computer to do scans and TTI stands alone but also can connect to computer.
3. Explorer exports CSV compatible with both WB and IAS.  TTI exports work in IAS but need to have headers edited out for WB.
4. Explorer, connected to computer, saves CSV there while TTI needs to have Sneaker net to move files.
5. Explorer costs $415 for 6G version with software.  TTI PSA1302 Costs $1395.00.
6. Explorer uses laborious keystrokes to enter frequencies and TTI has keypad on touch screen
7. Explorer has very low rez B&W screen compared to TTI Color screen
8. Explorer has no on screen graticule. TTI has Frequency and level with labels,

Examples of scans in same location below

Pete, when you say "explorer" , are you referring to the product "RF Explorer" ?

If so, which model?

Thanks

Just curious.  What's up in 4850-6100?  anything we as production professionals would ever need know about?

The fact that 5G WiFi didn't occur to me is probably why i'm not an RF tech.  :)

Thanks.

Hi Pete,

Super novice RF guy here that just ordered an RF Explorer WSUB1G 240 - 960 MHz model, so this comparison is interesting. There seems be areas of the two scans with pretty big differences in RF, is that correct? If so, is that due to the time differences in between taking the scans?

Also, would you recommend conducting scans with whatever paddle or whip antenna is used on the wireless system to be utilized, or are the antenna's supplied with these scanners fine for general use?

Thanks for sharing so much RF knowledge with the community.

These scans were taken about the same time the difference is in how the receiver works.  Explorer is not as fine an average as the TTI  Because iof the time of the scan- over  minute- the dynamic range seems to be larger in the Explorer.  A scan is not a quantitative measurement - just a way to see what TV stations and other interference there is so the normal whip antenna is fine.  Sometimes you might connect your SA to the actual antenna system you are using to see what effect it might have but not for the scan which really wants more of an omni antenna.

Pete,

I've been hoping for a post like this.

I am considering buying an RF explorer for basic wireless microphone coordination simply because I cannot afford anything more expensive right now; would you consider the RF Explorer a viable starter unit - so long as one recognizes its shortcomings/peculiarities? Are there any other units you'd consider usable for someone starting out in RF coordination? Handheld, computer-based, etc.

YES, I think it is very usable.  There are some cheeper ways to do it but not with the RF coordination features of RF Explorer.

Thea's good to hear, especially from you.

I tend to use Wireless Workbench since most of the devices we bring in are Shure brand, so the ability to import [current] scan data with little/no tweaking is a plus for me.

IAS and a quality RF analyzer may be in store some day, but I can at least keep learning/experimenting until then.

I have the Kaltman Win radio scanner I bought a few years back and have compared it to the RF Explorer and if I were to do it over again, would just buy the Explorer.
It really is good value for basic RF scanning and is much better than using just the scanners in the RF receivers.

Given the price difference between the basic WSUB1G model (which covers standard UHF TV frequencies) and something like the 6G Combo, is the ability to scan VFH and Wi-Fi frequencies generally worth it?

Thanks!

More equipment will be moving to VHF like the RAD UV-1G comm system.  Wifi you can scan better with your laptop.

I just got an RF Explorer, the WSUB1G+ model.  It's pretty cool, and even way out here in the suburbs I'm able to see some TV stations - very sensitive, more than I've been getting from our TTi's.  Agreed that the user experience is a little clunky compared to the TTi, but still very usable.

For the price, and the size, definitely cool to have. I've been wanting one that'll be able to ride with my regular tools.

Hi Scott, long time RF Explorer user here. Yes, It's sensitive... but pay attention to desense in presence of strong signal (also out of your scan range). If you want to verify, just open communication with a walkyes 50mW at 1 meter from half dipole antenna connected to RF Explorer and you'll see what happen. (so... stay away from IEM transmitting antenna also...)
