1.2 Compact i and iX Series Differences
The compact i and iX 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 i Series AC sources. Where relevant, the “iX only” comment is used to indicate that
specific commands apply only to iX models.
1.2.1 Phase Selection
Single phase models 751 and 1501 do not support any of the phase selection commands listed in
this programming manual. These models only have a Phase A output and no phase selection is
possible. Phase selection commands are INST:NSEL and INST:COUP. These commands apply
only to the 2253i and 2253iX three phase models. SCPI Commands that can be used to operate
on a specific phase are indicated with the “Phase Selectable” phrase below the command syntax.
This means that on a 2253i/iX, using the INST:NSEL and INST:COUP will determine if a specific
phase or all phases will be affected when the command is executed. Other commands such as
measurement queries only apply to one phase at a time regardless of the INST:COUP setting.
For these commands, INST:NSEL is required to change between phases.
1.2.2 Firmware differences
The iX Series is fully featured and supports all commands listed in the programming manual.
The i Series provides most basic functions in its standard configurations. On i series models,
commands related to arbitrary waveforms and harmonic analysis measurements are not
supported and will generate a “-113 Syntax Error” message.
1.2.3 Hardware differences
In addition to the firmware differences described, the following hardware differences exist
between the standard iX Series AC source and the i Series AC source.
• The iX Series comes standard with both GPIB and USB interfaces. An optional Ethernet
interface (-LAN option) is available.
• The i Series comes standard with USB only. An optional GPIB interface (-GPIB option) is
available.
• The 2253i and 2253iX are equipped with an RS234 interface in addition to USB.
However, only one interface can be used at a time and connecting the USB interface to a
PC will disable the RS232 port (and LAN option if installed on 2253iX).
Note: All interfaces use the SCPI command syntax as described in this programming manual.
1.3 Manual organization and format
All user documentation for California Instruments power sources is provided on CDROM in
electronic format. (Adobe Portable Document Format) The required Adobe PDF viewer is
supplied on the same CDROM. This manual may be printed for personal use if a hardcopy is
desired. To request a hardcopy from AMETEK Programmable Power Division, contact customer
. There will be an additional charge for printed manuals.
