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).
Key Specifications
Sweep | 200 ns/Div to 5 s/Div, 1—2—5 |
---|---|
Triggering | > 0.4 Div or 50 mV to 1 MHz, > 0.6 Div or 200 mV to 20 MHz |
X-Y mode | 50 mV/Div, 180 ns rise time, 2 MHz bandwidth, 1 MΩ // 24 pF input |
