[vslist] Persistency in CRTs, oscilloscopes

[Per Magne Knutsen]

We require a display with fast refresh rates and very short persistency. From the literature, many opted 
for oscilloscopes such as the Tektronix 608 that uses the fast-fading P15 phosphor. From our vendor, 
however, we are told this model is based on analog technology "dead for 10 years".

Can anyone advice on what displays are nowadays used when fast refresh and short persistency is 
required? What is, for instance, the persistency of a flashed image on a "regular" PC monitor?

Also, I find no CRT monitors with vertical refresh rates in excess of >160 Hz. Do faster monitors exist? 
Again, for how long does the image leave a trace behind when flashed on these monitors?

For newer, digital, oscilloscopes, the persistency is tunable, but apparently only down to 50 msec. Are 
there better performers than this? Manufacturers? Models?
