The '''Tektronix 5B25N''' is a "digitizer time base" for the [[5223]] scope, i.e. a time base that also contains a sample clock generator. | |||
It will also operate in 5400-series mainframes as a generic time base. | |||
The 5B25N/5223 system uses real-time sampling at sweep rates of 0.1 ms/div or slower. | |||
At sweep rates of 50 us/div or faster, equivalent-time sampling is used. | |||
The 5B25N uses the [[155-0109-01]] trigger chip (U95). | |||
