The Telequipment D755 opt 66 is a 50 MHz scope. It is a government version of the Telequipment D75 with the addition of an XY-mode.
The D755 takes two plug-ins that are also compatible with D83, D75, D63 and DM63. Vertical plugins include the V4 dual trace amplifiers, the V3 single channel differential amplifier, the V1 single channel amplifier, and the V5 single channel amplifier with delay line. Timebase plugins include the S1 single timebase and S2C dual timebase. The preinstalled plugins in the D755 are the V4 dual trace amplifiers and the S2C dual timebase. Calibration fixtures include the 067-0672-00 plug-in for the vertical slot and the 067-0673-00 plug-in for the horizontal slot.
