MAT FULL RACK/ 022300

3. To enable the output, the Host Computer sends:

CLS :CH9(cr)(lf)

4. To verify the previous command was implemented the Host Computer sends:

STA(cr)(lf)

The Power Module Controller sends back (if no errors occur):

(sp)(cr)(lf)

5. To measure the current at the output the Host Computer sends:

FNC DCS CURR :CH9(cr)(lf)

The MAT at address 9 is now set to take a reading

6. To take a reading the Host Computer sends

INX CURR(cr)(lf)

The MAT previously set up now starts to measure and sends the proper time delay
needed for the measurement (See Par. 3.4).

The Power Module Controller will send the time delay back to the Host Computer when
it has been Talk Addressed (see specific IEEE 488 interface requirements):

00(cr)(lf)

7. The Host Computer then sends

FTH CURR(cr)(lf)

The MAT then sends the measured (in the example it is 3.9998 volts) current in scien-
tific notation to the Power Module Controller

The Power Module Controller in turn sends:

3.9998E0(cr)(lf)

8. To measure the voltage at the output, the Host Computer sends:

FNC DCS VOLT :CH9(cr)(lf)

The MAT at address 9 is now set to take a reading
