I don't know if they are still selling them in the states or not, but I 
bought a hitachi 100mhz dual tracer about 18 years back and its beat 
the socks off a tek anytime I've fired it up. 

Try this with your tek, look at the output of a sampler test point on 
the antenna feedline of a channel 8 tv transmitter in an emergency when 
you don't have a good diode or demodulator to watch/monitor it with.  
Thats about 181 mhz.  The hitachi V-1065 I have reproduces it quite 
faithfully at up to about 5 major screen divisions high and saturates 
very cleanly if pushed farther.  The teks amplifier saturation cutoff 
will stop it at about 1 division high, slightly informative maybe, but 
not good enough to measure modulation depth.  And it sold for about a 
thousand $ under the tek 2235 at the time.  Much better (better focus 
and brighter) crt too in the Hitachi, mine is as clear and well focused 
now as the day it was new & the stations 2235 is sickly on its 2nd crt 
now.  It has some computer measuring stuff builtin that the 2235 didn't 
have any of too.

The V-1085, even fawncier will do this too, but its triggering falls 
over on video waveforms making it essentially worthless for tv 
applications of any kind that involves the varying apl of live video.

Theres a V-1585 on ebay ATM that might bear checking out.  Effectively 
new, I've no idea what his min bid is.
