The '''Tektronix 7B90P''' is a digitally programmable 400 MHz time-base plug-in for the digitizing mainframes of the [[7000-series scopes|7000 series]].
The '''Tektronix 7B90P''' is a digitally programmable 400 MHz time-base plug-in for the digitizing mainframes of the [[7000-series scopes|7000 series]].
All controls are programmable except for the sweep calibration screwdriver adjustment and the external trigger input terminator switch.
The local/remote state of the 7B90P is slaved to the local/remote state of the mainframe.
