The U800 is made byTektronix 155-0241-02, was replaced & properly heat sinked, bottom & top The LV power supply filters (Capacitors) replaced with units with better specifications The A5 control Board SMD capacitors were replaced & potted P> Calibration provides both accuracy tweaks & tests the system limits. The system will not Calibrate if a faults exists. I calibrate repeatedly during trouble shooting and re-calibrate before shipping.
$5 BIN gets you the Tek IC 165-2393-00 which is very similar to 155-0237-00 U600 vertical out IC used in 24__ scopes. These are used, but still good. Roughly speaking, 165-2393-00 will limit a 400MHz scope's bandwidth to about 360MHz, whereas a 155-0237-00 will let it work to around 450MHz.
The rear frame is updated to 2465B type with a new Fan The U800 is made byTektronix 155-0241-02, was properly heat sinked. The LV power supply filters (Capacitors) replaced with units with better specifications Calibration provides both accuracy tweaks & tests the system limits. The system will not Calibrate if a faults exists.
I am offering you a tested good triggering A1U500 IC for any of the 2400series analog scopes like 2465, 2465A,... Tek would have charged at least $250 for one of these until the late 1990s, when they quit supplying them. Also, from 1995 on, those Tek supplied labeled "Maxtek" instead of "Tek" proved to be less reliable.
I am offering you a tested good Channel Selecting U400 IC for any of the 2400series analog scopes. Tek would have charged at least $250 for one of these until the late 1990s, when they quit supplying them. Also, from 1995 on, those Tek supplied labeled "Maxtek" instead of "Tek" proved to be less reliable.
