The '''Tektronix 7912HB''' is a scan converter based digitizer in the [[7912|7912 series]], [[introduced in 1988]].
It is an improved version of the previous [[7912AD]], increasing bandwidth to 750 MHz (using a [[7A29P]] amplifier).
 
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).

===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|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.
