5B42
The Tektronix 5B42 is a 60 MHz dual timebase plug-in for 5400-series scopes.
Key Specifications
| Main Sweep | 100 ns/Div to 5 s/Div, 1−2−5; ×10 magnifier (i.e. down to 10 ns/Div), variable ×2.5 (i.e. up to 12.5 s/Div) |
|---|---|
| Delayed Sweep | 100 ns/Div to 0.1 s/Div, 1−2−5 |
| Delay Time | 0.2 to 10 times the TIME/DIV setting |
| Trigger | DC or 50 Hz (AC) or 7.5 kHz (LF REJ) to 10 MHz at 0.4 Div or 100 mV; 10−60 MHz at 1 Div or 400 mV |
| Ext Trig In | 1 MΩ // 20 pF, max. 350 V DC + peak AC or 350 Vp-p AC |
| X input | 50 mV/Div, DC or 50 Hz to 2 MHz |
Internals
The 5B42 uses several Tek-made ICs − two 155-0109-01 trigger circuits, a 155-0049-xx sweep control, and two 155-0042-03 or 155-0028-00 Miller integrators.
