Range Error Checking
The instrument uses the following method to check for range errors.
1.
Active settings are limited by MINimum and MAXimum values. The active settings considered are only
those relevant to the output coupling. In AC+DC coupling, both DC and AC voltage settings are act-
ive, so range checking is applied to the peak absolute value of the combined waveforms.
2.
In addition to the immediate DC and AC voltage, in Step mode the triggered voltage setting
(VOLT:OFFS:TRIG or VOLT:TRIG, depending on the output coupling) is also checked to ensure that an
accepted trigger does not cause an invalid state.
3.
Frequency settings are independent of range, output on/off status, and output coupling.
4.
Output coupling and output range may only be changed when the output is off. Therefore, the instru-
ment always checks for inconsistent settings when you try to change the output coupling or range
before turning the output on.
5.
If output coupling settings are changed, the Range Error Checking and Soft Limits Checking are both
made for any parameter that becomes active as a result of the output coupling change.
6.
Settings that are valid on the low output range are always valid on the high output range, but the
Range Error Checking and Soft Limits Checking are both performed whenever the instrument is asked
to change ranges in either direction.
Soft Limits Checking
1.
The soft limits are checked only if soft limits are enabled at the time the soft limits are set or at the time
when the soft limits are enabled.
2.
Soft limits can be configured for DC voltage, AC voltage, and Frequency. The soft limit check is inde-
pendently performed for the AC and DC components in AC+DC coupling.
3.
Soft limits also apply to the corresponding trigger values of DC voltage, AC voltage, and Frequency
but only in Step mode.
Settings Error Checking
These settings verify that the voltage setting is correct.
In AC and DC output modes, the setting must be between the range's MIN and MAX values.
In AC+DC mode, an additional check verifies that the peak voltage does not exceed 194.5 V (low
range) or 389 V (high range).
If soft limits are enabled, the instrument checks that the setting is within the low and high soft limits.
Settings errors are checked when the user changes the mode setting to Step mode.
