8.2 APE Command Language (Abbreviated Plain English)
The APE (Abbreviated Plain English) command language syntax is available as an option on the
Ls Series only. This option is not offered on Lx Series models. The APE language provides
backward compatibility with California Instruments‟ L Series legacy products.
This option is bundled with the GPIB interface option on the Ls Series. If present, Ls Series units
of similar power and voltage rating can be used to replace L Series in test systems running
programs written using the APE syntax. The presence of this option can be determined by using
the *OPT? or SYST:CONF? command queries. Note that the Ls can always be operated in SCPI
mode as needed. If the
–APE option is installed, it can be switched to APE mode. In APE mode,
the IEEE488.2 common commands such as *IDN? are still available but not SCPI commands.
This section of the manual covers the APE syntax. Note that the SCPI command language is still
available as well. The Ls can be configured to power up in either mode of operation. The
procedure is as follows:
From the front panel, select the CONFIGURATION screen using the MENU key. In the
CONFIGURATION screen, select the LANG field. This field can be toggled between SPCI
or APE using the shuttle knob.
From the bus, send the following commands depending on the present mode of
operation.
Present Mode To change to other language mode, send:
APE mode SCPI
SCPI mode SYST:LANG APEN

8.2.1 Introduction
Remote programming through the IEEE-488 Interface (GPIB) consists of sending the unit address
and the proper ASCII alphanumeric characters to identify the parameter and the numerical value
or other argument. The description of the abbreviations for GPIB messages used in this section
is listed in Table 3-10. These abbreviations must not be confused with the device dependent
abbreviations used to describe the AC Power System operating parameters (ex. FRQ=Frequency,
etc.).
