If you get the "Sorry, the file cannot be displayed. There seems to be a technical issue ..." error when trying to view an image, a workaround is to click on the cog icon in the upper right side of the media viewer, and then select "Disable Media Viewer". We are aware of the problem and are looking for a solution.
The Tektronix 834 is a portable "programmable data communications tester" (serial protocol analyzer) for RS-232 (V.24) circuits, introduced in 1980. The 835 and 836 are sister models with extra features, introduced in 1986.
It can be used as a serial transmission monitor, modem or terminal simulator, or as a bit and block error rate tester (BERT). It supports ASCII, EBCDIC and hexadecimal displays on its 12-character alphanumeric display, for data formats with 5 to 9 bits/ character (including parity), asynchronous or synchronous (including HDLC), from 50 to 19200 bits/s.
ROM packs were available to extend the 834's functions for specific protocols.
In simulation mode, operation is user-programmable with up to 99 program steps that can reference up to 50 "parameter buffers" (registers). Some standard tests like all-character tests or "quick brown fox" tests are predefined.
