The Tektronix 7912AD is a scan converter based digitizer in the 7912 series that succeeded the earlier R7912 in 1978.

It has 500 MHz bandwidth, introduced a standard GPIB interface into the 7912 series, and could drive X-Y monitors directly. In contrast to the earlier R7912, the readout characters in video mode were created digitally and directly injected into the video signal.

For the 7912AD and 7912HB, special GPIB-controllable plug-in modules with a 'P' (Programmable) suffix were available, e.g. 7A16P, 7A29P and 7B90P.

The 7912AD was succeeded by the 750 MHz 7912HB in 1987 (using a 7A29P amplifier).

Key Specifications

  • please add

Options

  • Option 4: Change to fast digitize mode. This option trades off scan time with resolution by compressing the scan. The target is written on and read from a 256 x 256 point matrix with a maximum of 14 points stored per vertical scan. This option is achieved by setting the correct jumpers on the A16, A20, A22, A26, A46 boards.
  • Option 13: Changes the video output to 625 lines/frame with a 50 Hz field rate (PAL). This option is achieved by setting the correct jumpers on the A20 and A28 boards.

Internals

Three output methods are provided: Video (NTSC or PAL), X-Y-Z low-speed analog, and a GPIB interface. For video-out, Tektronix recommended the 634 monitor or a monitor from the 650- and 670-series and a 75 Ω termination. For X-Y-Z analog, Tek recommended a 600-series monitor and no specific termination requirement.

With aftermarket modifications to the electronics, 7912AD bandwidths have been extended up to 3 GHz in special cases.
