menu) sends the HP-GL command string to the analyzer’s HP-GL address. The address of the
analyzer’s HP-GL graphics interface is always offset from the instrument’s HP-IB address by 1:
n
If the current instrument address is an even number:
HP-GL address = instrument a 1.
n
If the current instrument address is an odd number:
HP-GL address = instrument address 1.
Special
Two HP-GL commands require special consideration when used in local operation or in
sequencing. These are explained below:
Plot absolute (HP-GL PA)
The syntax for this command is where x and y are screen location coordinates
separated by a comma.
(HP-GL d: LB)
The syntax for this command is LB[text][etx]. The label command will print ASCII characters
until the etx command is seen. The etx is the ASCII 3 (not the ASCII character 3).
The title function does not have the ASCII value 3. so the instrument allows the LB
Entering Sequences Using HP-IB
You can create a sequence in a computer controller using codes and enter it into the
analyzer over HP-IB. This method replaces the keystrokes with HP-IB co The following
is a procedure for entering a sequence over HP-IB:
1. Send the HP-IB command where x is a number from 1 to 6.
2. Send the HP-IB commands for the measurement.
3. Terminate with the HP-IB command DONM (done modify).
Sequences HP-IB
An external controller can read the commands in any sequence (in HP-IB command format).
Send the following command to the analyzer:
where x is a number from 1 to 6.
Allocate an adequate amount of string variable space in the external controller and execute an
ENTER statement.
