Data Length Considerations
When one of the following commands is sent from a controller to the HP
4155A/4156A in the HP 4145 syntax command mode , the HP 4155A/4156A
outputs data to the controller.
DO Data output request in the system mode
TI Current measurement trigger and data output request in the user
mode
TV Voltage measurement trigger and data output request in the user mode
ID Identication output
Dierent Data Length in System Mode.
The following program is equivalent to sample program 1 listed in Section
3 of HP 4145B manual. This program is an example of data output in the
system mode. This program controls instrument to measure the IC-VC
characteristics of a bipolar transistor, then returns IC data to the controller.
10 ASSIGN @Hp415x TO 717
20 DIM A$[1100]
30 OUTPUT @Hp415x;"IT1 CA1 DR0 BC"
40 OUTPUT @Hp415x;"DE CH1, 'VE', 'IE', 3, 3; CH2, 'VB', 'IB', 2, 2; CH3, 'VC', 'IC', 1, 1; CH4"
50 OUTPUT @Hp415x;"VS1; VS2;VM1; VM2"
60 OUTPUT @Hp415x;"SS VR1, 0, 1, .05, 50E-3; IP 10E-6, 10E-6, 4, 3"
70 OUTPUT @Hp415x;"SM DM1; XN 'VC', 1, 0, 1; YA 'IC', 1, 0, 10E-3"
80 OUTPUT @Hp415x;"MD ME1"
90 A=SPOLL(@Hp415x)
100 IF BIT(A,0)=0 THEN 90
110 OUTPUT @Hp415x;"DO 'IC'"
120 ENTER @Hp415x;A$
130 PRINT A$
140 END
You must execute this program in the HP 4145 syntax command mode of
the HP 4155A/4156A. The following will be displayed on the controller's
screen. (Or you can display on HP 4155A/4156A's screen by changing the
select code/HP-IB address assigned in line 10 to 800 , which will execute the
program using built-in IBASIC of the HP 4155A/4156A.) As you can see
, the
length of data string A$ is to short, so not all the data is displayed.
