Method of testing with computers
First Claim
1. A method of testing a unit with a test instrument and with the aid of a master, an intermediate and a slave computer, the latter being connected to said test instrument for sensing its measurements, comprising the steps of:
- dispatching one of a plurality of instruction signals to said intermediate computer from said master computer;
issuing to said slave computer, when it is not halted, a signal to halt from said intermediate computer after receipt by the latter of one of said instruction signals, said signal to halt being provided in response to one of said instruction signals;
transmitting from said intermediate to said slave computer, after the latter has halted, that one of a plurality of command signals corresponding to the currently received one of said instruction signals;
altering the state of said slave computer in response to that one of said command signals transmitted from said intermediate computer, the altering of the state of said slave computer being directed by said master computer without any change in direction originating from said intermediate computer;
forwarding a go signal to said intermediate computer from said master computer;
issuing to said slave computer from said intermediate computer a run signal signifying a request to run and sense measurements from said test instrument; and
performing successive measurements with said slave computer without successive authorization through said intermediate computer.

Abstract
In this method, a unit (24) is tested by a test instrument (22) with the aid of a master (MC), an intermediate (30) and a slave (SL) computer. The latter connects to the test instrument (22) for sensing its measurements. The method includes the step of dispatching one of a plurality of instruction signals to the intermediate computer (30) from the master computer (MC). Another step is issuing to the slave computer (SL), when it is not halted, a signal to halt from the intermediate computer (30) after receipt by the intermediate computer (30) of one of the instruction signals. Another step is transmitting from the intermediate (30) to the slave (SL) computer, after the latter has halted, that one of a plurality of command signals corresponding to the currently dispatched one of the instruction signals. The method also includes the step of forwarding a go signal to the intermediate computer (30) from the master computer (MC) and issuing to the slave computer (SL) from the intermediate computer (30) a run signal signifying a request to run and sense measurements from the test instrument (22).

9. A method of testing a unit with a test instrument and with the aid of a master, an intermediate and a slave computer, the latter being connected to said test instrument for sensing its measurements, comprising the steps of:
-
dispatching an instruction signal to said intermediate computer from said master computer; sensing whether said slave computer is halted and providing information to said intermediate computer indicating whether said slave has halted; halting said slave computer through a halt command transmitted by said intermediate computer; and decoding said instruction signal with said intermediate computer to direct it into one of a plurality of routines, one of said routines causing the intermediate computer to direct the slave computer to run its current program for operating said instrument, another one of said routines causing the intermediate computer to relay data from said slave to said master computer.
-
- 10. A method according to claim 10, wherein said another one of said routines causes transmission to said intermediate computer from said slave computer part of its memory data.
-
12. A method of testing a unit with a test instrument and with the aid of an intermediate and a slave computer, the latter being connected to said test instrument for sensing its measurements, comprising the steps of:
-
dispatching one of a plurality of instruction signals to said intermediate computer, said dispatching occurring in response to manual intervention by an operator; and transmitting from said intermediate to said slave computer that one of a plurality of command signals corresponding to the currently received one of said instruction signals, said command signals including singular requests for said slave computer to;
a. operate said test instrument, b. stop after executing one programming instruction and c. return a signal corresponding to the data stored at a selected memory location in said slave computer.
