Programming Manual
Lx \ Ls Series II

The following are two formal documents concerning the IEEE-488 interface:
ANSI/IEEE Std. 488.1-1987 IEEE Standard Digital Interface for Programmable
Instrumentation. Defines the technical details of the IEEE-488 interface. While much of the
information is beyond the need of most programmers, it can serve to clarify terms used in this
manual and in related documents.
ANSI/IEEE Std. 488.2-1987 IEEE Standard Codes, Formats, Protocols, and Common
Commands. Recommended as a reference only if you intend to do fairly sophisticated
programming. Helpful for finding precise definitions of certain types of SCPI message
formats, data types, or common commands.
The above two documents are available from the IEEE (Institute of Electrical and Electronics
Engineers), 345 East 47th Street, New York, NY 10017, USA or via the web at

Lx Series and Ls Series Differences
The Lx Series and Ls Series of AC power sources are both based on the same AC power source
hardware platform and share many common components. The differences are primarily in
configuration and options. This manual covers both model series. Some commands listed may
not apply to Ls Series AC sources without the
–ADV option and / or –MODE option.
1.2.1 Firmware differences
The Lx Series is fully featured and supports all commands listed in the programming manual.
The Ls Series provides most basic functions in its standard configurations. More advanced
features can be added by specifying the
–ADV (advanced) option. If the –ADV option is installed,
all commands listed in this programming manual are supported. If not, commands related to
arbitrary waveforms and harmonic analysis measurements are not supported and will generate a
“-113 Syntax Error” message.
1.2.2 Hardware differences
In addition to the firmware differences described, the following hardware differences exist
between the standard Lx Ac source and the Ls AC source.
Lx has a 150V / 300 V rms output range pair. Optional ranges of 135/270 (-HV option)
and 200/400 (-EHV option) are available at time of order.
Ls has a 135 V / 270 V rms output range pair. Optional ranges of 156/312 (-HV option)
and 200/400 (-EHV option) are available at time of order.
The Lx rear panel connector labeling is compliant with the California Instruments iL Series
which it replaces and the HP/Agilent model 6834B.
The Ls rear panel connector labeling is compliant with the California Instruments L Series.
The Lx Series II comes standard with both GPIB, USB and RS232C interfaces. An
optional Ethernet interface (-LAN option) is available.
The Ls Series II comes standard with USB and RS232C only. An optional GPIB interface
(-GPIB option) and Ethernet interface (-LAN option) is available.
Note:
Both interfaces use the SCPI command syntax as described in the programming manual.
The Lx Series provides both three phase and single phase output modes which can be
selected from the front panel or over the bus.
