The result is returned in scientific notation, in ohms. As an example, assume that the 4300C is in the 2V
and .1mA ranges and the front panel display indicates "10567" which is 10,567Ω. The program above is
executed.
The 4300C responds with the following number (contained in A$):
+1.0567E+4
This is the measurement in scientific notation, in ohms. The "E" signifies a power of 10 4 , or 10000. This
means that the significant digits of the response should be multiplied by 10000.
In another example, assume that the 4300C is in the 20mV and 10A ranges, and the front panel display
indicates "1.9095" which is equal to 1.9095mΩ. The program is executed.
The 4300C responds with the following number (contained in A$):
+1.9095E-3
This is the measurement in scientific notation, in ohms. The "E" signifies a power of 10 -3 , or 0.001. This
means that the significant digits of the response should be multiplied by 0.001.
An over-range condition is indicated by:
+2.0000E±?
Each response is terminated with an "output data terminator" which is used to signal the end of the
transmission to the controller.
The default terminator is a
C
R
L
F
(carriage-return and line-feed). The terminator may be changed using the
"D" command. Refer to Output Data Terminator section..
4300C Command Set for GPIB
This section contains a description of all commands that are recognized by the 4300C using its IEEE-488
interface (Option TL-488). As noted earlier, the 4300C does not need to be queried to retrieve the
measured resistance data. The commands listed in this section are used to set ranges, turn the test current
on and off, and to setup internal communication protocol.
A condensed listing of the 4300C command set is given in Table 9.
When sending commands to the 4300C, an "input data terminator" must be used to signal the end of the
command line. The 4300C recognizes a _ (carriage-return) or EOI asserted with the last character as valid
input terminators.
Commands must be sent using upper case characters. Multiple commands may be sent on the same line
if they are separated by a comma (,).
