The Tektronix 7B90P is a digitally programmable 400 MHz time-base plug-in for the digitizing mainframes of the 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.
