Lx \ Ls Series II

165

Configuration Issues:

The following configuration related issues are unique to the Ls Series when operated in APE
mode and did not apply to the L Series:

1. The Square wave command (WVF SQW) is accepted only if the advance feature option

is installed. (Option

–ADV)

2. The System configuration language bit must be set to enable the APE option. See *OPT?

Command in SCPI syntax section of this manual.

3. SYSTem:LANGuage APENglish will change the language to APE when in SCPI mode.

4. SCPI will change the language to SCPI when in APE mode.

5.

Power source configuration queries should be done in SCPI mode. However the “TLK
CFGA” APE command will respond with a configuration byte similar to that of the L series
for backward compatibility.

6. The CFGA command will be accepted but changes to the GPIB listen address will not

take effect until input power on the Ls unit is cycled.

Power-on Initialization:

If the Ls Series AC power source is powered up in APE mode, the normal recall power up setting
from a user-assigned setup register will NOT take place. Instead a power on initialization similar to
that of the L Series is used as shown below.

The factory default values for APE power on settings are:

ALMA 0

FLMA 60 Hz

INIA 0

V

INIC n

A where n is the maximum current limit of the system at a given range.

APE Mode

SCPI Mode

ALMA 0 or 8

PONSetup:VRANge

FLMA

PONSetup:FREQuency

INIA

PONSetup:VOLTage

INIC

PONSetup:CURRent

Note: When upgrading the firmware on an Ls Series unit that has a firmware revision of 0.90 or

less, the above parameters must be reset in APE mode.
