Hi all,
RF coordination is becoming "real job" in Italy. So, after MANY years of RF Explorer use I'm searching a new, fast, precise analyser system. Kaltman RF Vue, that I used many times, is too slow and "problematic". I really need something fast to measure not just DVB-T but also intermittent signal (Walkyes, Led ecc.). And yes, money is a great concern (RF coordination is BECOMING etc.)
Extensive search on the web point me to Signal Hound SA44B.
Any comment will be appreciate, TIA 
I have been having a lot of success with my Siglent SSA 3021X. It goes down to 1 kHz RBW. I like to go through my frequency list during shows looking at a 1 Meg window. With a 10kHz RBW my sweep time is 15 milliseconds. It also had 750 horizontal pixels vs the TTI's 250. I paid $1400 US.
It comes with an included tracking generator. The interface is great. There are jump arrows and a knob for tuning and moving a marker.
It is only ten pounds so it is portable, but there is no battery so it is not a handheld unit.
I have imported scans into the demo of IAS (I work events as an RF guy where I am already provided coordination). I have not tried it in WWB.
Perhaps it would work well for you in combination with an RF Explorer for tracking down rogue users.
