This is because the length of data output from the HP 4155A/4156A and HP
4145B is dierent as follows:
HP 4145B data output format in system mode:
X+NN.NNNE+NN,X+NN.NNNE+NN, ... X+NN.NNNE+NN[cr][lf]
Each data consists of 13 characters (including a comma) except for the last
data, which consists of 12 characters.
HP 4155A/4156A data output format in system mode of 4145 syntax
command mode:
X+N.NNNNNNE+NNN,X+N.NNNNNNE+NNN,X+N.NNNNNNE+NNN, ... X+N.NNNNNNE+NNN
Each data consists of 16 characters (including a comma), except for the last
data, which consists of 15 characters.
X Data status
+ +or 0
N Numeric character
In this example, number of data points is 21 2 4=84 (21 Var1 steps and 4 Var2
steps). So, length of data string A$ should be at least 1343 (16 char 2 84
points - 1). Please modify line 20 as follows:
20 DIM A$[1343] ! <<< Modified 16 x 84 - 1 = 1343
The result display is as follows (all data is displayed):
