Figure 5. The Logging menu

Troublshooting when the legacy

command is not supported or

has syntactic errors

Rather than hiding the unsupported

legacy commands, the X-Series RLC

application allows you to display the

CMD ERR error messages, which

will appear in the Message bar as

an advisory message. It shows the

error format as: CMD ERR, <string>.

This will occur upon receipt of a

recognized legacy command that is

not supported by the RLC application,

or if either the command syntax or

any of its parameters are incorrectly

formed.

By toggling the CMD Error soft key,

you can enable or disable the display

of the error message.

Furthermore, the Logging menu

allows the user to scroll the log

window (Previous Page/Next

Page), to refresh and clear the RLC

command error log (Refresh/Clear

Log)—see Figure 5. The logging menu

is only accessible from the FPUI.

Figure 6. Setting preferences for the emulation behavior via the Preferences menu

Selecting preferences

for your emulation

Preferences allow the user to change

the emulation behavior to gain

usability, speed, or measurement

accuracy. However, the default value

for each parameter in the Preference

menu is the closest emulation of

legacy behavior.

In RLC mode, each preference is a

configurable feature. They can be

selected either via the FPUI or RUI.

Preference settings are persistent.

If they are changed by the user, they

are unaffected by mode switching,

language switching, mode preset,

or even power on. They are only

preset to their default state using

the Restore Mode Defaults key in

the Mode Setup menu via FPUI, or

using the commands, INST:DEF or

SYST:PRES:PERS.
