If you choose the SCPI 2400 command set, you will not have access to some of the extended
ranges and other features that are now available using the SCPI command set. In addition, some
Series 2400 code will work differently in the Model 2450 than it did in the earlier instrument. In the
Model 2450 Reference Manual
, see "Model 2450 in a Model 2400 application" for information about
the differences.
To set the command set from the front panel:
1. Press the
MENU
key.

Why am I getting a 5074 event code?
The instrument provides an interlock circuit on the rear panel. You must enable this circuit in order for
the instrument to set source voltages greater than ±42 V DC. If you try to assign a high-voltage output
and turn the source on when the interlock is not asserted, you see event code 5074, "Output voltage
limited by interlock."
The Model 2450 is provided with an interlock circuit that must be positively activated in
order for the high voltage output to be enabled. The interlock helps facilitate safe operation
of the equipment in a test system. Bypassing the interlock could expose the operator to
hazardous voltages that could result in personal injury or death.
