A device for simultaneously displaying unrelated signals processes the signals separately prior to inputting them to a multiplexer. Under control of a microprocessor the multiplexer. Under control of a microprocessor the multiplexer switches between the processed signals to alternately pass the signals to the deflection circuits of an X-X display device at a rate which does not interfere with other frequencies used in the environment where the device is used.

Simultaneous display of two unrelated signals

A remote master-slave control method uses a single command line from a master instrument to a slave instrument. Commands executed at the master instrument are transmitted to the slave instrument via the single command line, and are in turn executed by the slave instrument only if an operator controlled input is 'on' at the time of receipt of the command. For instrument setups a recall command from the master instrument will be executed by the slave instrument if the operator controlled input was 'on' at the time the instrument setup was stored.
