* 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. | |||

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